Horsehead and Flame - Widefield

This image represents six lucky hours over two nights, Halloween and Nov 1st. On the first night, exposures were two minutes each, while the next night they were half as long, so I'd have some calmer data to blend in for Alnitak. I might go as quick as 30 seconds next time; that focal reducer really speeds things up!

I don't mind saying I'm quite pleased with the subtle foreground colors too. I think the sheer number of frames (over 300!) helped with that.

Finally, I usually crop my images and remove gradient, but I think that this one is interesting right up to the edges, and it's completely uncropped. This is the full field of an ASI183MC Pro.

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.
