This is first light for my new 150DPS, so my first prime focus attempt. I'm quite pleased with the result Looking forward to getting some more data...

It's 16x1m unguided at ISO800, 10 darks.

SW 150DPS

Vixen GP+EQMOD

Nikon D70 unmodified (bypassing the star eater!)

Curves, levels and cropped, with the small galaxy NGC 6207 just showing in the upper right:

Here's a full field crop. I can't quite control the vignetting, I think I should purchase GradientXTerminator. Or try some flats?:

nice pic from a d70..not quite as easy as a canon.

Hi acme, you asked for details of EQMOD+Vixen GP, hope you don't mind me replying here.

My Vixen mount I bought second hand and came with skywatcher motors and control board (possibly SynTrek) I don't think EQASCOM is currently compatible with Vixen's own mount interface... But I may be wrong.

The MOD I have is here: Rother Valley Optics HEQ5 Mod | Telescope Accessories | Rother Valley Optics

All the EQMOD info you should need is here: EQMOD

Yes, I'm very happy with the detail the D70 is picking up - bypassing the "star eater" median filter has made a massive difference. (I notice you have a D50 - do you do the same?). Here's a 100% crop, pretty good detail I think for actual pixels:
