I am looking to get a 2nd DSLR/Mirrorless camera modified for some astro work, mainly nightscapes and night time lapses.

I would have preferred full frame but I have been told a modded camera is not ideal for nightscapes. Although I really like Alex's recent Milky Way panorama with a modified Sony Nex 5.

It seems to me to boil down to just a few choices. Tge Sony Exmor 16.3mp sensor APSc sized is in quite a few cameras and whilst it varies in noise performance in different brands it is a powerful sensor. Clean, high resolution, high dynamic range.

Bodies that have that chip are Fuji XE1 and Xpro 1, Sony Nex 3N, 5N, 5R and 6 (5R and 6 have the latest version of it which has autofocus pixels on the sensor itself), Nikon D7000, Pentax K5 models.

The next choice seems to be Canon EOS and most seem to be good. I am not sure one is much more of a standout than the others or does one -- (60D??) (except perhaps the 5D2,3 or 6D full frame). 60Da may be sensible in that regard. It doesn't need to be modified nor need a special filter for day shots.
But it probably cuts IR is less flexible than another type of camera with the clear filter modification.

Anyone using one care to give their impression of this camera?

Greg.
