Just another attempt at M42, in LRGB, without masking the Trap. This is a series of 30s subs (33 for each channel) with L used for Luminosity). Camera is the ASI1600MM-C, at -20C. Bias frames were used but no darks as the subs were so short they are not really necessary, Bias can suffice. Camera was set to Gain 76 Offset 15. Scope is a TS115 APO running reduced at F5,5. Mount is the CGX.

This was an attempt to create a reasonable image of M42 without overlaying (Masking) the Trap, which is the accepted way of producing the best detail wihtout blowing the core.

I have some Ha captured at the same time but it needs more data and different Gain settings to be useful , so I will reshoot those.

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.
