Looks like I will get some favourable weather in the coming days, but the moon is out and full. I finally have a car so I can get away from light polluted Weymouth, and tonight I took a drive and found a great spot to shoot (see image).
So to the point, I want to shoot Andromeda during these moonlit nights since the moon will be directly behind me. How much will it still affect my images?
I'm still a beginner, using a Nikon Z50 and the 50-250mm kit lens @250 (F6.3), but I do have a Star Adventurer now, so I'll go out and shoot if nothing for the practice (my polar alignments have been pretty good).
yesterday afternoon, the forecasts for the evening were good so I set up the 10" truss-tube Dobsonian on the terrace for cooling down. Actually in the evening the sky wasn't as clear as expected but the cirrostratus luckily did not harm too much. It could have been brighter but anyway ...
So I tried my new 2x focal extender with the 10 inch scope for the first time and magnified up to 370x. Seeing was okay and I really enjoyed travelling along the terminator from Plato via Copernicus down to Clavius. For the 10"er the focal extender is really an enhancement when viewing the moon and conditions are okay: I saw much more detail in Clavius as I have ever observed before.
This would have been a good sketching target but finally I decided to go for a sketch of the magificient Copernicus (named after the famous Polish astronomer by Giovanni Riccioli mid of the 17th century):
The crater floor was still completely in darkness, one could only see the bright, round rim of this 93km wide crater. The terraced slopes were just partly in the lunar sunrise yet. Obviously the central peaks are as expected lower than the rim - they were still hidden in the darkness. The two craters north of it are Gay-Lussac A and Gay-Lussac on the way to the Montes Carpates with their eastern parts already visible.
Here's the sketch:
