Will do it was just that is was a good clean night and seemed a shame to stick the Ha filter in the imaging train.

Very nice, lots of subtle detail

I couldn't resist a play.

I prefer yours but I was curious to see how the detail would respond to some extra processing.

[MikeD]

Nice contrast in your edit Steve.

Wow!!, you captured some nebulosity in that one Mike, very nice!!

BTW, where have your 'infamous' halos gone from around the stars

I only get that problem when imaging in Ha, this shot is Luminance.

Aaah!, understood.

I guess that makes your Halo thing, a bit of a real 'head scratcher' Mike.

I am not sure how ha filters work but it seems to me that it could be because the none ccd face of the filter

is not blocking the light as well as the ccd face( just a guess as it might not even be possible for that to be the case).

So the light comes through the filter and some is reflected off the ccd cover slip and when it hits the ccd face of the filter on its way back out it's blocked and bounces back on to the ccd as a halo.

I might try turning the filter in its cell one day to test the theory.

Its got to be worth a try I guess Mike.
