IC1848 center of the "Soul" nebula HOO

The moon is almost full, there's not much oxygen, but it's still there. A new corrector 0.95 arrived, with it the stars are smaller and the field is flatter, no wonder they write about relative from 3 to 6. The aperture ratio is now 3.14. Today is the first frost -15, but I managed to insulate the entire tube with foil foam, as a result the mirror did not get covered with frost, without it it would freeze.
