This is another finished target for this season.
I (quite) recently bought a TS Photoline 102 ED with FPL53 which performs surprisingly well for a doublet. So I put it to tests and imaging, in parallel with an older FPL51 AstroProfessional 102 ED doublet.
The blue color correction is much better in the newer TS. I shoot luminance often with both and then take the highlights from the better scope.
For this image I also used some older data that I had available, shot with a 130PDS, but that maybe only made my life more difficult. Not that otherwise I shot data through the refractors in a single panel with reducers/correctors, but also in 2 panels with no reducing correctors. Same about the RGB. Some shorter exposures from the backyard, some from a dark site, most of the G data from a dark site, B and R from home (clouds came in at the dark site) and a lot of other adventures.
But in the end I managed to put them all together and made an image out of them.
You can watch it in full resolution and see other details on astrobin: Great Orion Nebula
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:
