M45 LRGB 28 Jan 2019

I started this as a test image having swapped my QSI camera from the C14 to the 4" APO early in December, after completing the Blue Snowball on 9 Dec 2018. My primary intention was to shoot some widefield in Orion during Dec/Jan with the Witches Head top of my list. Unfortunately the weather since then has been such that I stuggled to get enough data for an LRGB image of M45, never mind shoot the lower Witches Head. I finally got a entended period of clear sky on 28 Jan 2019, though even then transparancy was poor, with increasing haze and passing cloud as the night progressed, but with the upcoming forecast again poor I pressed on. The blue channel data in particular turned out very poor, with large halos around all the main stars, which has fed through into the final image.

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.
