I looking for a replacement for the Canon 350D that I bought used a few years ago. The 350D has several limitations compared to newer cameras. When the time comes to replace my Vista computer, I doubt there will be a driver for such an old camera. Focusing is tedious without live view. The ADC is only 12-bit. (New cameras are 14-bit.) Highest ISO is 1600. I'm not that concerned about its 8 megapixel resolution. With my 4 inch refractor, image scale is 1.7" per pixel. It would be 0.75" per pixel with an 18 megapixel camera.
Two candidates from B & H are the SL1 ($400 including 16GB memory card and 60D ($480 without card). The SL1 goes to a higher ISO (25600 vs 12800). The 60D shutter speed is faster (1/8000 vs 1/4000). The SL1 is Digic 5 while the 60D is Digic 4. Overall, I suspect the 60D is a better camera whose price has been reduced due to its age. However, that may not matter for astrophotography.
Are there any gotchas I should worry about with either camera? I should mention that I want to continue using the two Canon zoom lenses I bought 15 years ago for use with a 35 mm film SLR. One is labeled EF 28-105mm 1:3.5-4.5 and the other EF 100-300mm 1:5.6 L. I use the longer one at 300 mm for DSOs too big to fit within the frame with my refractor. The 60D works with both EF and EF-S lenses whereas the SL1 works only with EF-S. I don't know what that implies for my lenses.
