Long EAA session

Taking advantage of the absence of Moon (moonrise after midnight) to do some EAA.

Tried to simulate "Sonoma conditions" by using the Telrad instead of the laser and a newly acquired portable power station instead of the power outlet on the house.

Thanks to the plate solver, using the Telrad was fine even though few stars are visible with the naked eye.

After two hours or so, the computer battery was almost empty, so I plugged it into the power station. I drained most of it to get the computer back to 80%. Then I drained the computer battery again in less than two hours. After four hours, I had to go back to the power outlet from the house.

I had trouble getting good pictures: maybe the seeing conditions were not that great and/or stacking at f/5 (no FR) is challenging (a lot of ignored frames). Also the tracking was not great, I did not change the anti-slip tape on the EQ platform, and the occasional slip introduced visible star trails in my stack.

For the first time, I used DeNoise AI by Topaz Labs to clean up the pictures afterwards.
