I can't fit all of Kemble's Cascade in my field of view. It's a long line of stars that cascades into a pool of stars that is the open cluster NGC1502. Two nights ago I had a forecast for a couple of hours of clear sky then clouds. So I thought I would grab that to run the NINA filter focus offset calculator. My filters are LRGB non parfocal. I worked out the focus offsets manually back in the summer. When the offset calculator finished the sky was still clear so I set up to run a sequence for NGC1502 that I put together earlier in the day. Well I managed just 45 minutes of NGC1502 then when the humidity topped 95% and the dew point came within 1°C of the temperature I parked the telescope and closed the roof. I did some calibration frames and shut everything down. It was good to get the filter focus offsets done. Some more data would have been good, however, the 45 minutes does show NGC1502 to be a thing of beauty.

Re: Kemble's Cascade
Thanks Hans
It's in the constellation of Camelopardalis (which is a Giraffe, not a Camel Leopard hybrid!) It's a lovely binocular target.
