90 mm refractor, Chameleon 3 (ICX445), poor seeing. Small surge, and something boiling on the limb (30-second intervals, 0:30 h total):
Off-band; I like how everything seems more lively, will definitely try again (30-second intervals, 0:24 h total):
GSO RC8; better results than before, but I don't know yet which of the following helped the most:
- better seeing, for longer periods
- more frames to stack thanks to a faster camera
- replacing (as advised by Apollo) the Lunt's mini-ERF (colored glass) by Baader 2" Hα 35 nm filter; maybe I had been having thermal issues after all
Best frame:
