Software/control Issues with a D5500 or D7200?

[RobertYork]

I'm considering dropping money on either a Canon or Nikon body for astrophotography (as I put in another post in the general forum). I'm leaning more heavily towards Nikon at the moment from a sensor perspective. Since BYN is fairly new, and support for Nikons in astrophotography in general is hard to come by, is there any gotchas or things I should know before getting too committed to getting a Nikon over a Canon? Am I going to be annoyed by software or control issues at some point? I've already heard about lack of mirror lockup control. While that isn't a problem for me, it makes me wonder if there's other things that would bug me or cause frustration. Does it have proper PHD2 support? Stuff like that.

Mirror Lockup support isn't an Issue for DSO Imaging (or shouldn't be - Mount / Scope provide Structural Rigidity while Long Exposures collect very little light in that first 1-2sec before Mirror Vibrations have dissipated).

 

PHD2 Support is NOT Dependent upon any choice of DSLR Camera Make or Model - especially since PHD2 now provides for both Manual Dither and a Side App that performs Timed Dithers to mesh with Intervalometers and Image Generation Apps that don't have direct PHD-Server Support.
