Chasing Comets... (Just one, really...)

TL;DR: Anam and I missed shooting the comet NEOWISE in 2020 on our first attempt (on a weekend) due to clouds and the monsoon in general. Led to a crazy roadtrip on a weekday night in the following week and finally capturing the comet - some of my self-proclaimed best astro work. See photos below.

P.S.: Just like my innovation with Pre-Scripts, TL;DR here means you are "Too Lazy; Didn't Read" :)

2020 did have a silver lining - all the time spent with loved ones was not something any one of us imagined. It was fun to work from home - with all your favorite TV shows or movies playing in the background (if you're wondering, that is my usual work-flow - I like having some familiar show/movie playing in the background - helps me keep focused, I guess - feel free to share more WFH tips and tricks in the comments :))

Like I have mentioned in my recent post, I started a photography hobby sometime in 2018 (around my birthday, when I made my parents gift me a semi-pro camera - Sony A6000). Now, photography has its ups and downs - making time for shoots amidst a busy work schedule and home life can be a challenge, but of course, the satisfaction of taking and publishing (read as posting on Instagram - @artbymunaf) the photo is a rush (the likes and comments help, obviously). This post is about one of our (my and Anam's) most tiring experiences with my laborious hobby - there are several of these stories, which I plan to share going forward.

Living in Southern Arizona has its perks for a photographer - especially the astro-inclined ones. Part of the reason I got into astrophotography was visits to this observatory - Kitts Peak and reading about the dark sky locations nearby. Having spent most of 2019 driving around Arizona, Utah, and California for some of the best dark skies and making some investment in equipment like a star tracker (allows you to take longer exposures for light objects in the night sky by compensating for the Earth's rotation - that was a mouthful!), 2020 offered very few travelling opportunities, what with travel restrictions, hectic work, and school.

July 2020 rolled around as normally as you can imagine - we had all been stuck at home for a few months already and I was itching to get out and shoot some more night skies (having already captured some Milky Way shots that I loved). That was about when the Comet NEOWISE started showing up in our night skies - seeing NEOWISE behind basically all the landmarks in the world wasn't helping with the lockdown syndrome. As luck would have it, Tucson has a monsoon season which decided to start around this time as well. In terms of things that disappoint astrophotographers the most, it goes - full moon, light pollution, cloudy skies, in no particular order. After waiting a few weeks for the skies to clear near home, I decided to take things into my own hands and drive around in search of dark and clear skies.

It all started Saturday, the 18th of July - as I was keeping an eye on RADAR weather maps for the past few weeks, I noticed that there was a chance (yes, just a 20% chance) that there would be clear skies at Picacho State Park (about a 50 minute drive from home). This was my cue to load up the car with all of my gear and some snacks to spend the night at Picacho State Park - we were all excited and reached there around 7pm (an hour and a half before sunset). Getting there was easy enough. After paying for the park entry with basically all the quarters in the car, we settled at a picnic area with some shade and a view in the direction of where NEOWISE was, it was now time to wait. The view from this spot had a few saguaro cacti and the highway (I-10) which I was already planning in terms of composing the shot with the comet (high hopes, I know). This is where we settled down and waited for darkness to arrive so I could do polar alignment (I was going all the way with my gear - NEOWISE was likely a once-in-a-lifetime thing). That is when the clouds started rolling in - it wasn't properly dark yet, so I was still cautiously optimistic. I did make use of the sunset colors and the subjects around to get some nice deserty shots like this one.. I know, the clouds here seem flimsy, but, trust me, it almost seemed like they knew where the comet was and were trying to hide it!


Anyway, after several hours of waiting there (NEOWISE would already set by 10pm or so - about an hour and a half after sunset) and not seeing event a faint glimpse of the comet (either with our eyes or the cameras'), we decided to call it quits for the night. This of course, wasn't our first rodeo - I have had several such experiences with clouds, equipment failures, and in one instance, Coyotes (this is a long story and warrants its own post). By 9:30 or 10pm, we packed up our gear and headed back home. As disappointing as it was, I was more determined to capture the comet in the next few days.

Thankfully, from a work standpoint, I had completed a tape-out a couple of months back and was working on new projects which kept me occupied during the workday, but affording some time off in the evenings. Anam hadn't started grad school yet, so we were okay with trying something out on a weekday. The weather forecasts weren't looking promising - and NEOWISE was going away real fast! Desperate times call for desperate measures, as they say, so I expanded my weather map radius to a couple of hours away from home. I did not want to go and stay at a hotel (it was still the early-ish COVID days, so we did not want to risk it), so it had to be a there-and-back trip.

A small note about dark sky spots in general - they are usually isolated with very few people frequenting them. This makes them a bit - for want of a better word - creepy, to say the least. They are invariably away from cities and off the beaten path. Now, I have come to terms with having astrophotography for a hobby, but Anam is still getting used to the isolated nights under the dark night skies.

Back to Wednesday, July 22nd. After extensive research (read Google maps and weather searches), I had a plan in my head - to use a small rest area on I-8 (actually just a pull-out from the highway, called (aptly, I might add), Table top Roadside Tables - about 90 minutes from home to finally capture NEOWISE. Being ever the engineer, I did have a psuedo-back-up plan (which is what ended up being). We started from home about 5:30pm after work to allow for dinner and petrol breaks. Picked up dinner from our favorite Italian place and off we were! Here's a map for reference, in case you are interested:


The skies did not look promising where we were, yet. Even as we were reaching the first planned spot (the roadside tables), cloud cover was about 50% of the sky (very scientific data here, from the driver's seat) and mostly still covering N/NW (where NEOWISE should be visible). As we approached the pullout on to the "road-side" tables, the cloud cover did reduce, but N/NW was still covered. The pullout was but just a glorified parking lot - presumably for highway drivers to park and rest for a few hours if needed. There was enough room for setting up our gear, but then, clouds. There was one truck parked there, but nothing else - it was also open to the highway without any separators. I pulled out my trusty cloud cover app and noticed that there was no way the N/NW cloud cover was going away anytime soon. Time for decisions had arrived. We knew I would beat myself up if I don't get another chance in the next couple of days to capture NEOWISE. We had already spent a couple of hours into this pursuit, so we figured, what is another 4-5 hours?

This is where the back-up plan comes in - to drive all the way to Dateland, AZ - which is a total of about 2.5 hours from home (one way). Thus started our adventure - to the hospitable sounding "Sentinel Rest Area, Westbound". This one was a fully equipped rest area in its own right - with amenities like rest rooms, concrete cabanas with benches (for resting, presumably), and vending machines. There was also excellent lighting for the night - which made us feel safer. The deal with Anam and I is to always listen to our guts - if it doesn't feel right, we don't pitch our gear there. This place felt OK, there was some activity - several trucks parked and resting and several cars and drivers using the amenities. The best thing was, the cabanas faced N/NW. After appropriate amount of stretching and resting, we started to setup the gear around 9pm. Timing was really perfect - the moon was new, so the chances of NEOWISE capture looked great!

We picked the cabana farthest away from the parking area (but still in line-of-sight, to feel safe), and started setup. Facing N/NW is great for polar alignment AND capturing NEOWISE, so, the setup was up and running in a few minutes! In preparation for this night, I had watched all YouTube videos I could find on capture tips and processing ideas as well. Especially useful was this chap called Peter Zelinka (excellent channel for astro gear) and I ended up using his suggested flow. I can give a long-winded description of the photos, but a picture speaks a 1000 words, so:


And a photo of gear (I will do a post about the gear someday..):


Once I had my fill of the comet, we stayed there until about 10:40pm and started the long and arduous journey back home. Reached home around 3am and the first thing I did was to copy the photos from the SD card to my computer - I was NOT going to tempt fate and risk losing these RAW photos. Once copied, we just crashed and fell asleep.

The next morning, we were up and running by 9am, but caught up with sleep after work. The editing had to wait for next night when I followed the tutorials to the "T" and got these photos and posted them. This took a few hours, but, boy, was it worth it!

All in all - a great late night roadtrip to the best of Americana - the rest areas and highways that define this country. The infrastructure that allows people like me to go nuts and make these trips is something I am always amazed by!

We did survive this ordeal, but I told Anam that I should probably look for a less arduous hobby. Glad she was up to being a partner in crime with my nuts hobbies! :)

Do see me on my pages on Facebook and Instagram @artbymunaf (of course, I'm gonna shamelessly plug my pages - what'd you expect!? :P)

Back after almost a decade...

Hello dear reader...

It has been almost a decade since I wrote something in this space. As the cliche goes, life is now different (much so) since I wrote last (Jul 3, 2011 apparently - :O)

It has been a wild ride - and I am sure we are all much better for it - if you even remember the existence of this blog. :P

The last time I wrote here... 

India had just won the ICC World Cup. 

I was still struggling through my Masters' degree (I was just in my 2nd semester at that point, so pl. bear with me). 

I was still unemployed - it is funny, now that I think about it - the coincidence of my stopping to write with my starting to be gainfully employed (either part-time or full-time). It is almost as if my job(s) replaced my writing... Geez!

America was still presided over by Mr. Obama, so, for better or for worse, it was different.

I still had a non-smart phone (a bright red flip LG at that) and used to be edgy saying "I am not a big fan of touch-screens) *facepalm* - of course this quickly changed when I was able to buy my first Android (Samsung Galaxy Nexus - untainted by Samsung's bloatware yet)...

And in the meantime, the past 10 years have brought great things into my life, and I am sure all in all of yours too...

COVID-19 has to take the cake for the most influential thing in the past decade - hopefully, the vaccines will tame this beast soon!

He-who-must-not-be-named (or more aptly, Umbridge) being the president for one full term and seeing the horrid news cycles spewing out the craziness.

A stable career and work that I enjoy doing (of course there are ups and downs, but, for the most part it is great fun)

The experiences that are unique to being a first-generation immigrant in the US - especially practically starting from the scratch in a brand new place - One thing I plan to write more about

Getting married - best thing that I chose to do

Getting into photography - just enjoying a hobby the most I can - another thing I would like to write more about

Reading (and more importantly, re-reading) a lot - this is one other thing I plan to write about - sort of book reviews, I guess, especially about things I have learned and understood better from it.

So, here's the lowdown - I just read something excellent about a gentleman's journey through his life from Hyderabad to the USA (spanning some 30 years so far) and this has sparked me to get back onto this pursuit of mine - link in comments.

Not going to make lofty promises of posts everyday, but may be once every few weeks about the things that have shaped me (esp. in the past decade) when I have been mute on this platform..

So, yeah - thanks for coming back to Musings with Munaf! Hope you read along and contribute when/where you can!

Freelosophy

DISCLAIMER: This post is a kind-of eulogy for everything in the software world that is free and open-source. And hence, I'm sure, it is understood I'm not being paid by FOSS or someone... :D


"...that we here highly resolve that these dead shall not have died in vain; that this nation, under God, shall have a new birth of freedom; and that this government of the people, by the people, for the people, shall not perish from the earth." - Lincoln's Gettysburg Address, November 19, 1863


"Given a large enough beta-tester and co-developer base, almost every problem will be characterized quickly and the fix will be obvious to someone." - Eric Raymond, 1997


"Only wimps use tape backup: real men just upload their important stuff on ftp, and let the rest of the world mirror it ;)" - Linus Torvalds, 1996






If you're wondering why I'm blabbering about all these oldies here and now (Lincoln was old, Raymond and Torvalds, on the other hand, not so much...), you must not have been in touch with me or at he very least, my FB profile and status updates. I've been in touch with one of the most important sensations I have ever been into. By the way, this is the first post I'm typing on my laptop. I always wanted to do this - be free! Free as in freedom. Freedom from finding software that can serve all my purposes and yet, be free (this time, as in cost :P). Freedom from figuratively looking over the shoulder all the time trying to see if someone knows that you are actually using pirated software. In this aspect, India is very much ahead than probably any other nation in the world. Let me put this into perspective - pick up like 20 computer users in India, 19 of them use any of the versions of Windows. And of those 19, about 10 still use Windows XP. Of those 10 people, about 8 have never spent a buck (literally) on the Windows software they use or most of the times, not even for any other compatible software that they need to use on their machines like, for instance, Photoshop, MS Office, Matlab et al. OK, what is this post about? You might've guessed it - Linux.


First things first : It costs you only the time it takes to download it. Almost every version (a Linux version is called a Distro, short for distribution.) comes free. being true Indians as we all are, we like to get things for free.On the other hand, we have a never ending paranoia. Why is he giving this thing to us for free? It is probably defective, probably sub-standard. I had the similar doubts about Linux back in December '09. Did you know that, linux is probably the most standarized of all the operating systems available? Virtually every big corporation (and I'm talking real BIG) uses one of the Linux distributions - Red Hat Enterprise Linux, Ubuntu, Mandriva et. al. (Most likely Red Hat, though.)


Why did I venture into this? I've been asked this a lot - at least ever since I started rallying about Linux and especially Ubuntu to any living soul I know :D. OK, why? Back in December, I was planning on buying a laptop and had started researching for a good one (and so far, I have found it). What I found common with all brands was - laptops with Windows cost a considerable amount more than those without the same. It was during that period that I learnt a lot (a LOT) about things like processor architectures, OS architectures and other technical things. The irony is that - I was supposed to have known them for like 3 subjects that I took and yet, I found the fun in those subjects. Mostly because, knowing things is different from learning them (for like an exam or for an assignment). So, i thought, what other options do I have - for an Operating System. I wanted it to be cheap and or once in my life, I wanted it to be legal. On my desktop, I use a shared (between friends and all) version of Windows XP, which incidentally, cost me nothing :). I wanted my laptop to be totally free (except for the hardware, of course) and yet, legal, cutting-edge, and reasonably user-friendly. That was when I stumbled upon Linux. I pored over thousands of lines of reports, bench-mark tests, and technical details and ended up choosing Ubuntu, especially because it was just about a CD's size and of course, meant for personal users.


Now that I've answered the obvious question, another question. Linux is free, huh? What if it's all a conspiracy and all they want is your personal data and corrupt it all. (Trust me, I've been actually asked this.) Let's face it guys, you are not the center of the universe. No one is out there to get you, let alone all the silly things that make up your data. No one simply cares. And even if they do, Linux is at the very least as safe as the other options you have. Viruses, on the other hand, are a totally different issue. They are not aimed personally at anyone, no? Well, this next thing is not so much because of Linux's (come to think of it, any *NIX), omnipotence, but because of the smaller user-base of the *NIX OSes. There are practically (I can't emphasize this enough) no wild viruses for Linux - as of now, at least. That certainly is one less thing to worry about, don't you think?


True, Linux comes with a learning curve, a very long one at that. I've been using Linux for about 2+ years now, and yet, learn at least one new thing every week - try to beat that with Windows. And, I'm not even talking about any software, just the OS by itself.


Well, I'll leave you to figure out the rest of Linux. If you are at all into technology, I suggest you start using Linux - not great for games, but the thrill of learning something so pure...unbeatable!!


An excellent article I read about the differences in philosophies is here...do go through it and of course hit the Distro websites.




Ubuntu - My personal favorite
CentOS - My second favorite, just a clone of Red Hat Enterprise Linux - Stability
Fedora - Just a cutting edge version of Red Hat
Distrowatch - Reading material on all the Distributions


"...the Linux philosophy is "laugh in the face of danger". Oops. Wrong one. "Do it yourself". That's it.
- Linus Torvalds, 1996


Cheers!!

The day that was - Part II

After having finally finished finals and doing well, Alhamdulillah, I'm getting back to the blog (read as block :P). Well, the holidays here are so boring that, I have been on Facebook for pretty much all of my in-somnolent time. And of course I have started developing this very very serious LaTeX fetish and have decided to do all my Lab reports and other submissions using LaTeX. Refer to my FB status dated May the 13th for my exact views on LaTeX. (And if you really care for that, I suggest you get back to hitting the books, enough of holidays for you.)

Well, no more beating about the bush (isn't that what I'm doing now? :P). OK, we had just paid like 500 bucks to the cops and this part of the episode still has an awesome repercussion which we will get back to. Anyway, and as C was kind enough to remind me in the comments of the last post, B's bike did not have a valid Pollution check on him and thus the hefty fine. Me and C were just standing on the other side of the signal and waiting for the drama at the traffic island to be over so we could be  on our way to having some serious FUN! At this point, I have to agree that we reached Mount Opera in pretty uneventful circumstances (although, I'm a bit surprised at that now...). Well, these things happen, don't they, another group of our friends was there too (no point wondering about the odds, there are only so many days you can avail the offer... :P). Now, remember the "two large soda"s which got us the tickets? Surprise, surprise! The sodas had gotten warm-hot (not even room temperature) thanks to the raging sun and our delays at the police and stuff. And now, we were all in a fix! We had spent so much on the sodas (no, the tickets actually do not count!! You seem to be weak in Hyderabadi math!! :P) and we were not gonna just throw them there! God forbid! I was not so brave though, I had left my two sodas at home see *patting my back*. So, the other group and A and B and I think D actually drank the warm sodas and as an eye witness, I heard things like Kya pinda hai yaaron!! Phenyl ke jaisa hai! and Chee re bhai! Phek dena tha!! Ab kya kya hota ki!?!. For the first expression, I just realized, Dude!! Tu phenyl kab taste kara patthey?? and kaiku tho bi!!! Well, we were through the gates and rode on to the actual fun (or did we walk, I don't remember...). Anyway, the fun was about to begin and it was gonna be legen-wait for it-dary.

We were just walking around the place in the beginning and there were these weird Dinosaur statues all around and we finally made it to a Columbus ride (the one that looks like a ship and swings all through) and thought, what the heck! and got onto riding it. Here, the highlight was D's face. He was so contorted, we were all laughing all through the 15-20 minutes of the ride. We still lament the lack of a camera on the side facing D so we could have captured the moment and make him embarrassed for the rest of his life :P. Well, and after roaming about for another hour or so (if you are wondering what we did "roam"ing, think big park-large expanses of grass-all the weird possibilities for the curious mind. I'll leave it at that. Then came the real fun part, the water rides.

I need a bit of a preamble before I even begin these events. First of all, I cannot swim although this will not matter in the events that transpired, it seems worth a mention. Also, those were the good old days when I used to use contact lens (and due to an idiosyncratic problem, they had to be hard a.k.a. RGP lens, look it up if you care...) and I had been very confident (read cocky) that it wouldn't matter with all the water around. That's pretty much it though. Well, we took up a locker and a couple of briefs for using the water rides (they wouldn't allow us to go in our own underwear, would you believe that!! :P). Well, A and D had brought their own swim-wear which needs a mention but, I shall not go into it. Well, among all of us, we had like, let me see, 5 sets of keys, all the bikes and the locker combined. And A had a pen-drive on him too (although I don't see the point of, in retrospect). Well, first stop was the wave pool!! We left our pants on the shore (can you call it that?) of the pool and dove in. It was fun for quite sometime. And yeah, I did not mention that I had left my bike keys and the locker keys in D's swim-chaddi(?)'s pocket. As luck would have it, the fly of the pocket was broken and could not hold the keys (I don't blame the fly...). Lo and behold! We had lost my bike keys and our locker keys (just imagine going home in just our pants (literally)). The problem of the locker keys was solved easily enough. We had to pay some 300 bucks to break the lock and get our clothes back. But, my bike keys!! Just imagine having to ride 50kms back home to get the spare. Well, I'm not complaining there, either. We found this life-guard guy who we told our case to. He was kind enough to tell us that he would keep an eye open (like he could see under-water). But, somehow, he found my key and we got it back and left it in the locker this time. Then came the log-rides!!

And of course, after a plethora of photographs in swim-chaddis, which if released to the public, none of us will ever get married in the future (just kidding! :P), we headed to the log-rides and well, let's face it me and B were kind of bigger than, you know, *log*s.  One of them was open and pretty straight forward and we went on it just once - you know, they make you take stairs for like 3 floors to reach the actual place to slide from. Well, the rides were fun per se, but the landing - WOW! For one who can't swim, it can be the worst nightmare ever! I was under-water for like 20 seconds before I actually surfaced (although I think my weight was the culprit there... :P). Then there was this innocent-looking ride with just about a floor's worth of convoluted tubes (yes, closed ones) seeing which I thought, eh! I can take this any day. Well, it was when I was actually in the ride that it hit - what if I get stuck in here (like Monica in FRIENDS :P). And of course, the ride was so convoluted that, the turns actually hurt!! And after just hanging around in the pool for another hour or so, we decided to call it a day!! On the way, we might've touched on the rain-dance room about which I will tell you in the next part...

Well, enough for this part...There still is the end and the actual consequences of the trip and finally, the moral of the incident. We did indeed learn a few awesome lessons from this one...

The next post would probably come pretty soon, what with me having so much free time this time around...

I almost forgot...pics!!
Picture of a Picture taker...Just after reaching Mt. Opera

I have absolutely no idea what I am trying to do...
