Messier 4 - Bathed in the light of a supergiant

Another one from Wiruna. I've always loved this glob, but missed seeing it through any of the big dobs at the SPSP, so on the last night thought I'd see what the QHY9 could do with a limited number of exposures.

Purists may point out the glare from Antares is showing up weaknesses in my budget imaging train, but I like the effect from the rays that's come out as I processed this one. Suspect I've ended up with more colour and less noise than I deserved for so few frames, but then again, it is a bright one. This exercise creates a new problem though - the majority of my old Messier pics are looking a bit obsolete now. Have posted an earlier effort with the 450D for comparison (taken 6/6/09 with 4 x 2.5 mins subs) ISO 800). Guess I'll have to revisit many of those in my collection until I'm happy.

Thanks for looking...
