The Keyhole Nebula - 20 minutes of the best data.
I selected the 4 best 5 minute LRGB frames & stacked them with 3 x drizzle & reprocessed for just the Keyhole area.
Of course the result is more noisy but I can get away with it because the nebula is so bright in this area.
The FWHM was approaching 3 arc seconds for many stars.
