Barnard 33 - Horsehead Nebula & IC 434

Another project that I always wanted to try, combining images from different sources and see if it improves. I took 5 minute exposures in Hα with my 6 inch achromat and a flattener so that the full 1200mm focal length came into the game. In general Orion is only visible from my backyard when it is still lower in the sky, and in the most light polluted direction as well. I combined those with my latest image with the 4" APO, and created a crop of the Horsehead to see how much detail I can achieve. Not that I am super happy with it, for the first try though I guess it is ok.

The Horsehead Nebula (Barnard 33) is a dark nebula in Orion. The Horsehead is back lit by the emission nebula IC 434, which glows due to ionization from the nearby hot blue star Sigma Orionis.

Description: Finally processed the Hß images that I took before I targeted Thor's Helmet. This final image is a composition of Hα amd Hß only. Green channel is 50% of each. To smoothen the image I added a composition of Hα-Hß-Hß with 50%.

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.
