Imaging: What's the Point?

Last night at Mt Pinos was less than expected with cloudy conditions coming and going and not predicted by the clear sky clock. Nevertheless, I could see 13.4 magnitude planetaries in Draco, and some pleasing views of the usual summer time objects and a rather detailed view of the Helix nebula. All of which involve what attracted most of us into astronomy: the fascination of discovery.
Now, it was a typical summer time night on a Saturday up at Pinos and yes that means the usual suspects were up there: the lookie lu's in force in battalion strength. Additionally, a commanding presence of imagers were up on the back of the parking lot doing whatever it is they do. Generally, I've come to learn that means bitching about their equipment not working or more likely, not knowing how to use it. And when the equipment does work and they actually know how to use it, a good number of them retreat into their RVs and booze it up while leaving their equipment set on "auto". In particular, one individual couldn't figure out how to use his stuff, and turned on a pair of head-mounted LED red lights and were about as bright as the typical 4x4 driving in at mid-night. That in turn attracted the rest of the imagers, buzzing around him and offering advice on computer programs, PHd guiding, and the like. It went on for hours. I'm trying to observe DSO's and these guys are firing up their laptops and their lights with complete disregard for their fellow amateurs.
Frankly, that brings up a bigger issue: the reason behind imaging. I mean why do it in the first place? Granted, I see some very nice images posted on the AM. But you can also look at the astronomy picture of the day or view images remotely without the expense of buying your own equipment. And some amateurs do image remotely while at home. But viewing an object in real time and observing many of them instead of imaging the same object again and again--M13 and M31 were big favorites among the imagers last night--begging the question of how many times do you need to image the exact same object? It seems like imagers fixate on one object per evening, sit in front of a laptop staring at it, then bitch about it, go back in their RVs to eat and drink, come back out, if they remember to do so, and then bitch some more until they finally leave. What's the point of it?

Ah yes, one of my fond memories at Astrofest in ‘98 was the guy camped next to me loudly cursing at his laptop while his wife tried to calm him down. On the field we also had some visual snobs that screamed bloody murder when a guy dared to open his car door and the dome light came on -- never mind the fact that a bright crescent Moon was still 20 degrees above the horizon!

Lots of weird, neurotic people in this hobby, and other than public outreach events, I prefer to observe and image alone.

The point? Some people enjoy it. There are things folks pursue do that I don't understand, but that doesn't mean there is no point to their interests. And there is a lot of creativity out there - it's not all just the same-old same-old.

The issue of excess lights is simply rudeness, or lack of concern for others, which seems to infect a modest segment of any group. (It can also be ignorance.) I understand things happen, so dark skies are sometimes interrupted by brief intrusions of white light (often by today's cars), so I don't get hyper about it. I sure will go ask folks who continually use white light or overly bright red light to please knock it off. It's better than just fretting about it and getting annoyed, and I can't recall anyone giving me a hard time about a polite request.

I just came back from Black Forest Star Party. I image because my eyesight is fading. Looking at M101 in a 20 inch dob only gives me a faint hint of spiral arms. But as to spreading light onto the field from my laptop I take every precaution to prevent it. Instead of the red screen filter I used 3 layers of ND filter material equivalent to 7 f/stops. That keeps the light to a minimum. Also, after 60 seconds the screen dims significantly so there's no obtrusive light. Also, I put my laptop inside a cotton duck enclosure that's draped around stacked camping tables.
Would I do it if I didn't have eye problems? Yes. Taking images is art. It's creating pretty pictures. That's the reason we image.

Some astronomers see things as they are and say WOW!

Some astronomers see things that were never really there and say it's AVERTED VISION.

Looking at the same objects year after year, they don't change or get any brighter or easier to see. Looking at Mag 12-18 Galaxies and seeing a faint smudge that has no details. No real color all black and gray with little details except for very bright objects. All these things can be said about visual astronomy. But that does not mean there is no point to it. Yeah, after many years of looking at the same 30-50 objects can be boring, but that does not mean they should not enjoy it.

So, what is the point of imaging. Seeing details that would escape the eye with the largest of portable telescopes. Seeing colors that make plain objects beautiful. Capturing images that you can enjoy anytime rain or shine and not have to worry about the Moon or peoples lights in the parking lot. Seeing things clearly when your eyes are not as good as they were when you were 30. Having your choice of 1,000's of objects to image instead of a couple of hundred that you can actually see in a modest telescope. These are things that can be said to explain why I image.

I have much more problem with visual astronomers with their headlight, brilliant red beacons that they shine all night to find eyepieces and to look at their charts. They also tend to leave earlier and the lights from their cars make everyone left at the site upset. Most imagers that I know are very concerned with their lights. They may go into their RV's and maybe some will have a drink or a beer, but they are over 21 and that is their business. Now getting drunk and wandering around the parking lot making an ass of themselves, well that is different. But at Mt Pinos it was the visual asses running around and grabbing your scope and wanting to point it to some object was my experience. Never had a drunk imager come around.

Mt Pinos is a public place and there are no rules or regulations that prohibit lights or other things. So you just have to put up with other people, they have as much right to be there as anyone else on the parking lot. If you want to control this kind of behavior, buy a lot some where and put up a fence! 8)

I guess the same could be said of Visual only. When I go out with my imaging gear I try to set up off the side of the field away from everyone else and try to have my laptop only visible to me. I have the dimmest setting on the laptop selected and I use a plastic red filter. I put red plastic tape over power lights and so on. Another thing I do I've done my own experimenting and trying new ideas out in my own back yard. Only when I know what I'm doing then I'll try it at the dark sky site. It helps to come prepared too. Yes I like to image some of the same objects it called getting better at it. smile

This is exactly why we have wars. People just can't get along for any length of time. We get on each others nerves. It's kind of like rush hour. Your driving in the country and come to a 4 way stop with another car. The guy waves you to go first. Now drive in rush hour where everyone is on top of everyone else and people will give you the finger, not let you merge on the freeway or let you out into traffic. We don't like crowds for some reason. Just human nature.

That is why I don't go all the way up to the parking lot anymore. Too much interference from campers and their "oh I am sorry headlights" and a whole heap of curious "non hardcore I just wanna peek people" I rather find a side turnoff and observe in solitude....maybe with two or three other friends....

Hi All,
I haven't posted in a while, and the Equipment Forum started to look like the Religion Forum of a few years ago! I'll make my point on a few points then get back to equipment.

I'm a visual guy myself. I have done Astrophotography. I don't call it imaging because that term is more associated with digital equipment than film. I wonder if I can still get film. I still have my trusty little Olympus OM-1. What's the point of Imaging? Floyd and others have said it, but to add my two cents, it is a hobby and lots of people enjoy different aspects of it. I see no point in using a laptop to layer up heaps of digital images when I have a handy link to HD versions of the millions already taken. So for me it's a visual experience.

That visual experience can be profound. I find it best alone, however Jennifer has taken a keen interest. We look for some forgotten corner of Arizona. Yes there are still a few forgotten corners of Arizona without gun fire or RV's parked close by. You just have to stumble upon one and call it good enough to try. Whether I were imaging or observing visually, I doubt if Mt. Pinos would be my first choice.

My public time is typically the first weekend of the Grand Canyon Star Party which is very enjoyable. Especially the new location. The park visitors this year were just delightful. After that first weekend we found more than one spot inside and outside the fence where we spent the requisite 20 minutes to set up. Dark still sky is in itself a rare find and a joy to behold.

Getting back to equipment. I own the best visual set-up I can afford and never had a regret.
If a site isn't working for me, I move on.

There's more than a few cents worth.
Thanks,
Steve
