Description

M78 is a quite easy target from a dark site, but, when you live under a light polluted sky, all becomes a challenge.
M78 field is crowded of faint nebulosity and gradient correction from light pollution becomes a nightmare.

One remark, my William Optics Type IV reducer/flattener was originally designed to work with APS-C sensors and cannot fully cover the field of view of my Moravian 16200 Camera.
This is why I'v added the circular vignette to the image.
