Description

Two hours of integration under probably one of the best city skies I have experienced so far, and yet it is very hard to get some detail out of this 12.2 magnitude galaxy.

I was also finally able to imrove the collimation of the telescope, something that hopefully will be helpful also for future imaging sessions.

Title: C6 at F4.6 with mono camera

Description: To appreciate how difficult this target is and how well the Equinox fared, compare with its this image taken with the Celestron C6 at F 4.6 and the ZWO ASI 178MM mono camera and integrating 262 15s exposures.
The sky transparence was the same and albeit the total integration time is about half, the C6 has more aperture and the mono camera is inherently more efficient.
