Viewing Report 25th April 2022

22:01 – 04:23

M96 galaxy in LRGB on the 12″. Focus position 20691. Started at 22:29. Set up for 4 hours before it disappears behind the trees on the West side of the Meridian. Looking to take 24 x Lum and 8 x RGB all at 300s. Left the dome running and off to bed.

M96 Luminance 300s

The next morning I reviewed the status of the dome and imaging run and it ran al night without a glitch which was great. However the focus drifted quite considerably so I will need to throw away some of the data. What I need to do is cool down the observatory and the mirror before hand which last night I did not due to the last minute decision to image. Also getting the temperature compensation working on the focuser would help, so maybe time to revisit.

I will do another run on M96 on the next clear night.
