Horsehead and Flame Nebula in Ha

Link: https://kurt-zeppetello.blogspot.com/

I was not planning on imaging this as I did it just last year and really want to go after the Witch Head Nubula. However, it was finally clear, the temperature was somewhat tolerable, and the moon was out so I decided to image this gem again. I was not totally happy with my image from last year as the Flame Nebula appeared to have the same color the Horsehead Nebula. I believe this was a result of using the UHC filter. It did bring out a great amount detail but I think it messed up the color a bit. This time around I will try out my new Baader Neodymium Moon & Skyglow Filter for RGB data and combine it with this Ha data.

I have been converting my raw exposures to tiff and then stacking them in DSS as I get better star fields, however, I believe I am getting better nebula detail by stacking the raw Ha exposures in DSS. It would be great if there was some photo expert who knows why and what the best way to process these but after doing this stuff for the last few years I believe there is no "best" way.

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.
