spiral light Posted June 18, 2004 Share Posted June 18, 2004 I know this is a long shot but I thought I'd give it a try. I'm mainly interested in folks who are tri-color imaging with a CCD camera. If not then feel free to post something of strange interest in this thread. www.windhamhill.com - Shameless Advertising! Link to comment Share on other sites More sharing options...

Hound Dog Posted June 18, 2004 Share Posted June 18, 2004 Well I used to but I had to give it up. It just takes too long to process the RGB Weight Calculations to determine accurate spectral curves. Yum, Yum! Eat em up! Link to comment Share on other sites More sharing options...
Gifthorse Posted June 18, 2004 Share Posted June 18, 2004 I used to do that too until I got a personal teleporter. Now I just shift around like a changeling and get free shit. http://flagshipmile.dmusic.com/ http://www.myspace.com/gifthorse Link to comment Share on other sites More sharing options...
Adamixoye Posted June 18, 2004 Share Posted June 18, 2004 I'm actually a semi-professional astronomer (i.e. a graduate student in astronomy). I have my own telescope, but I haven't used it much in a while. I have put together tri-color images at the campus observatory though with some lab students of mine, but it was pretty simplistic stuff. What are you wanting to know? I believe that is the greatest reply I\'ve ever read! I\'m not even joking. -- justinruins Link to comment Share on other sites More sharing options...

Wouldja?OK, here goes.. Instead of taking pictures through telescopes using film, CCD (ie digital cameras) can produce more clearer images with much less exposure time. In producing these color images they are exposed through 3 color filters (Blue, Green & Red) to produce a final image (the blue & green overlap but there is a gap between the green and the red to reduce, I believe, the effects of sodium from street lamps which emit strongly in that area). Most astro-images nowadays are produced using this method. www.windhamhill.com - Shameless Advertising! Link to comment Share on other sites More sharing options...

What are you wanting to know?What determines the range of the RGB spectral bands. I know there is a gap between the G & R due to sodium emission and the overlap in the B&G has something to do with the OIII (?) line @ 500nm. Any advice would be great (you can pm me if it is overly technical). www.windhamhill.com - Shameless Advertising! Link to comment Share on other sites More sharing options...
