Hard won data and only able to use 50% of it...maybe 30 minutes via 60 second exposures at 1600 iso of one of my favorite regions ..the chimney region as I call it..Nikon D5500 on the Bojan Widefield Mount
.
First neglected to check stuff and so captured in jpg unfortunately and although I took many darks they seemed to cause the image to degrade ..at least that seemed to be the issue as with them could not produce a reasonable result but stacking just jpg gave me something.
I used a cheap 50mm lens..about $150 from memory..the best focus showed there were problems but I went ahead and as you can see the stars are rather odd...startools could not fix them..however it is what it is and ok if you stand way back
. I was at 1.8 and maybe next time try higher.
The moisture caused problems which were worse than theinitialimages showed both with these and the other stuff thru the 80mm...anyways why stop that letting you get out and freeze half the night
