Dont know what you're talking about Clive.. That result looks fantastic... and 2.5hrs exposure is hardly a quicky!
haha I posted an image on friday night that was a total of 15 minutes exposure.. THAT! is a quicky...
This shot of yours is great.. the star colours are great, the nebula is well defined, colours are spot on, guiding looks sweet.. focus is spot on...
What more can you ask for?
Well done.. I look forward to a deeper image with more data added..
