Description

Third attempt using M42 (trying to improve on mistakes made before)...

Again with the new focal reducer, so on f/7, but now a bit more on spot regarding focalpoint (and :-) the OAG prisma not in the optical train and with additional bought spaces). Although still not good enough on target regarding the optimal backfocus distance.

This time I also tried to go "deeper" (catching more nebulosity data) by using lower gain values (unity gain and values above):

- 37 on gain 90

- 92 on gain 200

Guiding was far from optimal but now with some 2 minute subs as well. I really had to fight to get the color in balance and/or even a sparkle of blue.
