B33, IC 434 The Horsehead Nebula in HaLHaRGB

During my October trip to Casitas de Gila, Gila NM, I worked on better automation of an imaging session using two targets in a night. The early target was the Wizard nebula. When Orion was high enough in the sky, I switched to Barnard 33, the Horsehead Nebula. I also experimented with increased gain for imaging with the Hydrogen-alpha (Ha) filter. Since B33 is rather faint, I sacrificed dynamic range for increased signal to noise ratio. This worked quite well for the Ha data. B33 is a Ha emission nebula in the constellation Orion, located near the bright star Alnitak in Orion’s belt. With my Celestron 9.25” SCT fitted with a 0.7x focal reducer, I included the reflection nebula NGC 2023. This made processing of Ha and Luminance data a real challenge. The three brightest, bloated stars remain as a processing issue.

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.
