Hi Dennis,
nice shot!
Interesting about the disparity between software. I had struck that
myself on my few attempts.
10 x 20sec on the LUM.....maybe try more?
I know that several hundred can bring stuff up out above the
noise floor when I do the 'planetary' process on my deep sky stuff
with 5-15sec exposures.
I can easily reach 18-19mag with FL 1500mm and 12" aperture
but the DSI sensitivity I think and it's pixel/arc sec is the key.
Secondly....another angle might work too in combination with
the above: try resampling up to 2x with Bspline or other methods
before doing your processing.
This has worked to get a much clearer sharpening on faint stuff
in my deep sky stuff recently.
FWIW,
Steve
