A C14/F11 on a G11. This is some hair raising work Frank! My had goes off to you. Impressive details, though as you suggest perhaps a little soft due to collimation (perhaps seeing?). Keep them coming.
Hi All I've listened to the advice and while away for the past 10 days i decided to test whether I had indeed burned the core...which it seems as suspected that I had.
So i took a few test shots of 2 and 3 min exposure under near full Moon skies.
Nevertheless it revealed a bit more detail including the central star.
So i did a quick (very quick) repro including these test shots and include here
Thanks for the feedback
I will definitely re image this completely with shorter exposures next new Moon clouds permitting
Cheers
