LRGB Horse Head, Flame and NGC 2023

Only a very short amount of time (just typical of summer) and some mistakes in acquisition that were partly interesting to resolve. I mistakenly had the camera at gain 200 for half the luminance subs so Alnitak was always going to be interesting! I did an HDR luminance to keep it all together though and was reasonably happy with the resulting halo and extended diffraction spikes. No sign of the micro-lens issue with my ASI1600MM-Pro though. Alnitak was a bit square perhaps but none of the little bubbles. All quite noisy and rough but glad to finally have something of this in LRGB.

Description: Finished the red acquisition (just short of an hour of 10s subs) and added a little more Blue. Weather and position in the sky the big issue in getting more Lum, Green and Blue so will see how that goes.

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.
