This is a test image checking operation of my new imaging setup based upon the Takahashi FSQ85-ED ‘Baby-Q’. After running several V curves in FocusMax I took 12x 5 minute exposures of M45. This is a good test of the optics as the stars are very bright and are a useful check for spurious reflections.
I’ve built a new flat panel using a larger EL panel and some translucent polycarbonate. The panel is still a little bright and I’ll need add a little more attenuation to enable me to use somewhat longer exposures to eliminate shutter artifacts.
