Thanks JB. I quite like clusters which can be a bit of a challenge with a non anti-blooming gate CCD

Hi Allan. An upgrade to the focuser and bobs knobs for secondary collimation, a set of counter weights and everything in the imaging train is screw threaded but other than that it's an out of the box GSO.
. This is at native focal length and no flatteners are in the way but there is a pretty hefty crop here so you aren't seeing the outer 15% which is where there is the normal curvature given the chip size.
Thanks for the comments
