Last night I tried out the used 114/900mm reflector I fixed up a while ago. It’s got some astigmatism still, but I’m pretty happy with this result. Next time I may try using calibration frames.

A fairly short focal length for a refractor. Is it an appochromat ? Nice photo.
Actually I just typed the wrong word! It’s a reflector. One of the bog-standard spherical f/8 114s that I picked up cheap.
