Description

Newton 250/1250 on NEQ-6 + ASI 178MM-C + Baader LRGB
LRGB composition
L - 1100 x 10 s (gain 82%), unguided
RGB - 300 x 12 s (gain 86%) per channel
Offset - 50
300 darks per channel
setup scale - 0,41''/pix

Relatively good seeing but quite long exposure times (10-12s) so the detail is not so good like with short 1-2s subframes.
I think that this is the limit for what I can achieve with this object under my sky and with 10inch mirror.
