Some individuals have asked for an image showing the proposed location(s) of the observatory. So... Attached is a map showing one of the proposed locations...
Before I post these online I thought I would offer them to the Club Members. I have decided to get a one shot color camera for the convince. I have the ST-7...
I wouldn't call it an upgrade, more a shift to the left. Either the ST2000XCM (smaller chip, but the convince of oneshot), or perhaps one of the Starlight...
Hello All! The weather seems to be clearing just a bit (compared to recent weeks). If the trend holds, I'm going to go out to Leasburg tonight to look around...
Here's a weird one... Last night, we finally had clear skies in Southern NM, so I went out to evaluate the sky at a proposed club observatory site near Las ...
RIch, How about adjusting these so the sky background level is the same? Tony ... From: Rich Richins To: ASLC_Imagers@yahoogroups.com Sent: Sunday, August 05,...
Rich That is very interesting but I think most of us know that Upham is much better than your back yard. What I would like to see is the comparison of the...
Tony, I added sky background color to make them the same, but the polluted sample still had more trails. I'm sure that if I did curves adjustment, the dark...
I'll send that comparison. I shot three locations in the sky - just above the worst of the light dome, the Western sky, and straight up. I haven't yet...
Here's some numbers from last night's expedition. I took images using my 28-135mm lens set for 50 mm (no guiding). Three 60-second exposures were taken at...
... <snip> Yeah, that is interesting, isn't it? It also does not make much sense unless there was some sort of haze over Leasburg, or the camera somehow likes...
There was a concert, and the amphitheater was lit with theatrical lighting. I took the pics from the overflow campsite. I walked around the amphitheater site...
So here's my weird hypothesis (totally unproven)... Light from sky fog helped the sensor to see dimmer stars. Sort of like 0.5 (star) + 0.5 (skyfog) = 1 (as...
Not bad at all. Some film astrophotographers will partially expose a frame, basically bringing the background up to grey. This will cause more dim objects to...
So I wonder if a similar approach could be employed for DSLRs??? Could a properly applied, uniform, barely detectable light source improve the detector's...
I don't think that's possable Rich, 0.5 star plus 0.5 background should equal a S/N of 0....... Tony ... From: Rich Richins To: ASLC_Imagers@yahoogroups.com ...
Rich Has asked me to head up the observatory design and building subcommittee. I cannot and should not do it by myself. I need some volunteers that are willing...
I'm happy to help in any way I can. Steve Smith ... Rich Has asked me to head up the observatory design and building subcommittee. I cannot and should not do...
Thanks Steve You have some experience in this area don't you? I thought I heard a rumor that you built your own back yard observatory. Is there any truth to...
Your right Tony. Adding more light from a source other than the target adds noise not signal. The resulting S/N ratio goes down not up. If it where the other...
Maybe... You would get it out of the bias area. Seems like it would have to be separate steps, though. Simple for film, just do a double exposure. Can you do...
