M13 image is from 27.02., same night as previous IC 405 & IC 405 image.
Picture is scaled down about 50%
This one was hard to process doe massive light pollution defects,
gradient, LP noise and weak S/N ratio.
LX200 gps 12" @ f6.3
SXV-AO @ 10Hz
QHY8 for imaging
Lodestar for guiding
9 X 900s = 2h 15min.
I did a new version.
This time I skipped two frames doe the bad quality.
Now there is 7x900s.
I also used CCDStack positive Constrain deconvolution,33 iterations.
Images are updated.
