This is my second image of this classic astrophotography target, almost three years later. This whole region of space is located about 1,600 light years away, within the wondrous Orion constellation. IC434 refers to the "backdrop", the Ha rich red part of the image. In front of it is the famous Horsehead Nebula, while below the Eastmost star of Orion's Belt, Alnitak, is the Flame Nebula.

First lights galore in this image, with a new refractor, a new mini-PC and the IDAS NBZ filter put through its paces. Also a rather painful processing run, I decided to split the Ha and OIII data from the NBZ capture and blend them with the RGB OSC data I also captured - I used a 70% Ha weighting within the Red channel and a 30% weighting of OIII within the Green channel. My usual StarNet approach to doing this floundered, so I masked the stars in each channel before combining, which seemed to give a more pleasing result.

Thanks for looking!

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.
