I thought I would post this even though I did a stupid thing at the very end of my processing. I thought I would try one of the N Carboni star spikes and then flattened all layers or vica versa and then saved and as I was looking at it close up I have a star diff in the middle of the lagoon.
Taken through my Canon 400d unmod with my 50mm f3.2. 10 x 4 min ISO 400 with ICNR on with bias frames and flats.
Any feedback welcome.
Mark.
ps I love the ease of finding guide stars piggybacking the camera on the scope.
Thankyou all for the comments. Troy it was taken from my back yard on the Sunshine Coast Queensland looking west so I was not directly looking in the direction of the coast lights which I am about 10 km from. Also it was a new moon but no dark site ( I would love one of those ) and no light pollution filters.
