Instead of watching the same old Superbowl, I took my 80mm APO out for first light.
Got it for Christmas, but this was the first night with good weather!

Re: Nebula Photos on Superbowl Sunday
Nice captures I did the Rosette last weekend as I had never done it before, I have tried the flame and horsehead but have an issue with Alnitak as it causes my ASI1600 to micro lense and flair on the longer exposures especially with the Oiii narrowband filter going to have to experiment if we ever get any clear skies.
Also want ago at M42/M43 as you have done as it quite high now. So many target so few clear nights
Keep posting the images
Clear skies (Optimistically)
Cheers

Re: Nebula Photos on Superbowl Sunday
Thanks Nick.
All those targets and crummy winter weather! We had sort of a false Spring here this week and a few really nice days. Now winter is back with a vengeance.
I checked out your Rosette nebula photo... great detail in there giving it a lot of depth - nice!
