I use a 1000D for astrophotography at the moment and I'm considering getting a 60D to do double duty as an astro camera and for normal photography (replacing a 50D)
Here are my thoughts so far... on the plus side
- High resolution.
- Good ISO performance.
- Articulated high resolution screen.
- Excellent battery life.
- Heavier than my 1000D.
- Very large image files.
What I'm not sure of is how to work with the sensor... does anyone here use the 550D or 7D for astrophotography? How high can you routinely go with ISO... 3200, 6400? Does 18Mpixels help or is it just a lot more processing for little benefit?
Are there any considerations I've missed?
Thanks in advance,
