The Other Side of Orion's Belt

Alnilam, IC 423 and 426, and NGC 1990 (maybe?) in HaRGB

Everyone knows the Horsehead, but move to the next star in the belt and this beautiful patch of nebulosity comes into frame.
This area was a tough target. It required a lot of exposure time, and I cranked up the gain on my RGB to get some good signal. The gain increase yielded a ton of light pollution in my RGB masters, which required extra processing to try to negate.

Interestingly... there is supposed to be a reflection nebula around Alnilam, NGC1990, discovered by William Hershel in 1786. It appears in astrometry, but according to wikipedia... "visual searches and modern astrophotography have failed to identify the exact location and extent of the reflection nebula".

I'm happy with the results. Hope you like

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.
