After a very long period of inactivity I'm back.

Here the first test with modified Celestron C 9.25 with Baader focuser.
The new focuser is great but I'm not so happy of the image.

Unfortunately passing veils during the night ruined almost half of the frames....

This is a bicolor composition with a technique similar to this other image
