Processing practise whilst Devon skies continue to have total cloud cover.

Bert's M42 data found on the PI forum and also processed by pfile; this version is processed by myself. The challenge on the forum was to remove the persistent gradients in the left top and bottom corners. Some success, but not easilty done.

Bert's info about the setup:

This is 54x4 min in each of RGB

Astrograph is an Officina Stellare RH200 which has a focal length of 600mm and is F3. Clear aperture is 200mm.

FLI Atlas Focuser.

FLI ten position filter wheel CFW-3-10 with 50mm square filters.

Astrodon E series LRGB and HA, NII, SII and OIII 3nm NB filters. Also a continuum filter 5nm.

Camera is a FLI PL16803 which has a sensor size 36.8 X 36.8 mm.

The FoV of this system is 3.5 X 3.5 degrees.

Mount is a Software Bisque PMX.

Thanks you Bert and pfile.

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.
