MDM Observatory 2.4m Telescope Observing Report for 2021 Jun 08

Observer(s): Melso/Sitaram
Institution(s): Columbia University

Instrument: CHaS

Worked for 8.5 hours (all night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Cirrus, Winds Calm
   Mid: Clear, Winds Calm
   End: Clear, Winds Calm

Observing Summary:

A nice night on-sky with CHaS! Made some adjustments to the camera angle/ 
centering early in the night. Observed many of the galaxy and nebula targets
in our rotation and collected excellent images in the dark time! 

Detector noise pattern seems to be fainter or at least not a limiting factor after 
the adjustments made this morning. We are no longer seeing the diamond pattern, although maybe 
we see a low-amplitude different pattern (possibly because we now have such a low background).
We are not concerned about its impact.
