IC 1805 HaRGB Widefield with DSLR

First successful run with ES iEXOS-100 budget mount. First night was near full moon, so had ~8 hours of 120-second frames shot through l-enhance filter. Second night had ~8 hours of 180-second frames with same filter. Third night had ~8 hours of 120-second frames with no filter for realistic colors. Modded Canon 600D, Rokinon 135mm f/2 at f/2.8, guided with PHD2 and Ekos internal guider.

Processed in APP by extracting H-alpha from the l-enhance data, processed the RGB data separately, and then recombined as LHaRGB with Ha contributing both to the luminance and red channel. Stars removed from composite image with Starnet++, and then the starfield from the straight RGB data reintroduced in GIMP.

C&C welcome - first time trying to composite data like this, and I think I kind of butchered it.

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.
