Description

Mars at 17.5" apparent size (Nov. 14), medium to good seeing (1" according to meteoblue), but I think this is now the limit of 4100 mm effective FL with 3.6 um pixels on my 8" Newton.

1200 out of 20000 images used (10 ms each, Gain 250), after 8x stacking the same images with different AP grids ended up with almost indivual pixels having enough signal at high-contrast terrain features, even with 3x drizzle. Need a real (telecentric) 5x Barlow to go to 6000 mm next time, the limit for now seems to be not enough pixels.
