Dave,
Mono only.
Alex, yes on the night a few different types of sharpening work
better or worse. It seems to be seeing dependent.
Good data responds very well to Laplacian sharpening.
Average data goes better with Unsharp mask.
No science here....I just do what works.
Here is NGC 253 from last night just after midnight.
Seeing was better, focus was better BUT it all got diminished by
the fact 253 is closer to the celestial equator than Tarantula (60s-ish)
Alex...get some sleep man!!!!!!!!!!!!!!!!!!!
