DSLR Question...Please help
After pondering the vaious Astro-photo options, I've decided the easiest way
to get what I'm after is buy a reasonable DSLR camera. I want good results but am not looking for Hubble Quality. In fact, I really don't even want color images---I want BW images but with some detail. I will do a lot of lunar work, some solar too. I would like to capture DSOs as they appear in the eyepiece with a decent telescope---and perhaps a better but color is not important. Oh sure, I might occasionally play with color but really color is not important. The reason for DSLR is that I do not want to drag a laptop outside and all that is attendant with that mess. I now have a GM-8---the tracking is excellent. Can you point me to website with some BW examples? So---is there a DSLR that would achieve this without costing over $1,000 and not needing to be modified? Minolta would be great as I have a TON of Minolta stuff---all film. Thanks for the help, Doink |

DSLR Question...Please help
I got some pretty good results using the Nikon D-50 Digital SLR. It offers
a 6 Megapixel CCD, automatic dark-frame subtraction to eliminate thermal noise, ISO seetings of 200, 400, 800, 1600 ISO. The camera along with 2 Nikon lenses cost less than $1000.00. If you just want the camera body (no lenses) it will run about $550.00. I got good results on some of the brighter Messier objects with about 10 minute exposures using a Celestron 11 SCT at f/10. If you are shooting from the city, be prepared to do some processing to remove skyglow (it shows up as an ugly orange/brown color, which can be removed by image processing software). If you do decide to buy this model, be sure to purchase a remote shutter release (wireless), which is needed to do bulb exposures that exceed 30 seconds. The wireless shutter release will run about $25.00 or so. Hope this helps. And good luck in finding the right camera. "Doink" wrote in message ...

It is impossible to remove any kind of noise from an image, other than by filtering operations that also remove signal. Bias, dark, and flat frames remove various sorts of fixed-pattern systematic artifacts. _________________________________________________ Chris L Peterson Cloudbait Observatory http://www.cloudbait.com |
