Sh2-224 in Auriga - HaRGB

Sh2-224 is a supernova remnant and has faint Ha intensity. I decided to give it a try with Ha in my first attempt . It paired well with another target I was acquiring and despite a cloudy December here in the Valley, I managed a few good nights of data acquisition. This was an interesting workflow to get the RGB stars matched to the Ha image that was used both to enhance RGB and as a separate luminance channel. Blur and StarXterminator were most useful in making this happen and GHS was essential to get good initial stretches and then stretch starless images to create intensity and color contrasts. I could have pushed up some more of the faint Ha, but that really needed more exposure time to develop good contrast. I moved on from this target for now, but perhaps with a taste of this faint target, I will come back one day and add more integration time for Ha and also add the OIII that I know is hanging out in the area.

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.
