Re: [APML] Finally, Got A Half Decent Picture

Thanks Chris and everyone else who replied.

As it was my "first proper picture" I may have overdone the processing a bit
(especially the smoothing) and I'll have another look at the brightness in
the Trapezium area (thanks Marco).

I was just thrilled to get a "keeper" at last, especially in view of rotten
weather here past 8 weeks.

Chris, I'm still investigating the "artefact" around the bright star. As I
was using a refractor, there were no spider vanes or secondaries in the way.

Again, thanks to all that replied

PS. Hope weather clears up for those of you who are cloudbound at present
