Best DSLR for Astrophotography?
What do people think about which DLSR is best? I have read the Canon EOS
60Da is made for amateur astronomers and is the new equivalent Olympus OM -1 for those old enough to remember film. The H-Alpha response is the clincher here but if you want to use it for normal photography you have to tweak the images with photoshop or equivalent as I understand it. Which DSLR has the physically largest sensor / # pixels? Seems this would be the clincher for FOV. How about pixel size for Canon / Nikon top of the line DSLR's. By binning pixels can you set the size of the pixel to the scope resolution. Any winners there? Is Nikon a contender? Any one else who makes DSLR's to consider? How about weight, reliability, ease of use etc. I have not seen a comparison of DSLR's for astrophotography that take into account all of these factors. Thanks in advance for any info. |

The 60Da is intended for astrophotography, but is supposed to be OK for pictorial photography. There's been a review in S&T. Companies will modify cameras to replace the minus-red filters in stock dSLRs to increase sensitivity to 656 nm wavelength light. There are "full frame" dSLRs with 36x24mmm sensors, the same as a 35mm film frame and "cropped frame" dSLRs with sensors about 1/3 smaller in linear dimensions. The full-frame models are pricey. DSLRs don't do binning. I use a Nikon because it is what I have. I did not buy it specifically for astrophotography, but for "normal" photography. It does OK. A friend uses a Pentax. For specifications, look on the camera makers' web sites. Bud |
