Michael,
I was not aware of this spiral! Antlia isn't resplendent with notable DSO's, so this one has gone totally unnoticed by me
I'll make a point of having a Captain Cook at it next dark sky time I get. Or even have a shot at it from home with my video rig.
Lovely capture too. The soft glow of the galaxy with the brilliance, sparkle and colour of the foreground stars makes for a nice composition
Alex.
