m45_sharp_qhy247_g1000o200_4x300s

A short test shot with my new Sharpstar 20032 PNT (Parabolic Newtonian Telescope).

 

Scope: Sharpstar 20032 PNT

Camera: QHY247C

Exposure: 4 x 300s

Gain/Offset: 1000 / 200

 

It took me a long time to calibrate the optics and I think I did a pretty good job. A bit of fiddling with adaptors got the spacing right for backfocus.

 

But the actual focus on the images is slightly off, not sure if it moved after I set off the imaging run or whether I didn't get it right at the start.

 

No flat frame calibration carried out.
