Description

Abell 31 is 3rd object in my last project. Indeed I started to shoot it in 2019. I collected 10 hours data. It is planetary nebula 2000 light years away, not too far. But it is very faint. Even after 32 hours, my result is still noisy. It is a big one in planetary nebulas, it is still small in my 1000mm telescope. This is an object w/o much S2 signal, so naturally It is processed it as bi-color image.
