In principle, this is the "Extended Version" of an image that I had previously processed (https://www.astrobin.com/8fw3xu/0/). Extended means that this is a 2-panel mosaic that now extends the field of view south to the Carpenter crater. Secondly, I deliberately used a twice as large stack of 400 frames to achieve a slightly better SNR (signal-to-noise ratio).

At the bottom right of the picture, Cap Laplace forms the eastern end of the Montes Jura. On the far left at the terminator is the Babbage crater. Babbage is heavily eroded and is a tall boy at approximately 147 km. In the middle at the top of the picture you can see the Carpenter crater (59 km), which has an unusual two-part central mountain, which unfortunately cannot be seen here. In between is the heavily eroded large crater Herschel and the Mare Frigoris, which runs diagonally through the image. By the way, the two craters in the middle at the bottom of the picture are Bianchini and Harpalus from right to left.

This image is also one of a series with 2,5xBarlow plus IR-Cut Moon & Skyglow filter this evening and the resulting focal length of 5080mm. The quality of the color raw footage almost killed me during processing until I got the idea to look at the individual RGB channels separately. Even if I know the theory or physics behind it, the result was very impressive. The red channel brought the best quality by far. Green was a little worse and blue was very bad. So I only used the red channel of 200 frames out of 5000 for this picture. With mediocre seeing and a frame rate of 66 fps, I worked with a gain of 256 (42%) and a shutter speed of 6.6 ms.

I got the best results this time by pre-sharpening with AutoStakkert! (50% RAW) and then achieve minimal final sharpening with AstraImage and the functions Multiscale Sharpen plus Denoise. The final fine-tuning was then done with Lightroom.

As always, I'm also looking forward to harsh criticism and feedback.
