Description

This is the first image from recently acquired 10" Orion Newtonian Astrograph. I was very lucky to get it used for just $350 from a local guy. Technically it was in a perfect condition, except issues with slipping focuser under heavy load (which I fixed easily by some tuning), even almost no dust on the mirror! These large and fast Newtonians are awesome for collecting a lot of light in a reasonable time. This image currently is just a little bit over 2 hours of integration time. It is still quite noisy in the OIII channel, maybe I will get more data in coming days weather allowing.

UPDATE: Last night I've collected one more hour of OIII and reprocessed the image. This definitely helped with the noise and provided some additional details on the outer shell.
