M76 subs/frames taken during two nights, 21-22 Sep-2017 and in the moon light 9-10 Oct-2017.

It is composed as a LUM-Ha-OIII master layer combined with color layers, RHa, GOIII and BOIII.

The CCDStack2 program used for aligment & stack.

No calibration frames used and further picture processing enhancements done in PS CS6

Total exposure ~ 7.9Hours.

Lum=131x60sec+93x30sec. R,G,B=22,21,23x60sec. Ha=OIII=23x300sec.

The Atik Horizon beta camera temp. was set to minus 20 degress C.

My home build observatory is placed in my front yard/in the "red light" polution zone, have a look here,

Red Zone

Kind regards Niels

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
