[OzEclipse (Joe Cali)]

Alex,

Pentax K1 mentioned by Greg has an articulated screen, seems to have reasonable Ha pickup without modding has other built in features that assist with astrophotography.

Modded Canons seem to have very nice colour rendition (see Josh Bunn's wide fieldimages) but they are definitely a bit backward in terms of noise & performance compared to the three cameras with the new Sony 36MPx sensor - Nikon D810, Pentax K1 and Sony A7r.

The K1 and possibly the others, has an HDMI output. You can plug in a 12V HDMI video monitor, the type you attach to the back seat of a car so kids can watch DVD's and see the camera screen on a separate small monitor. Some are quite compact.

The attached image of M42 is taken with a K1 with total exposure time of 130s at f4. Obviously a bit of noise there, but outer neb was shot 15s @ ISO 12800 ;-)

If you want connectivity to software, get a Canon. If you want standalone functionality, Pentax & Sony. I have no experience with the D810 so refer you to Greg's comments.
