A Simple IC1805 and 1848 in H-a

Lightly processed IC1805 and 1848 in narrowband H-a. I wanted to see how far I could push my 135mm lens. Just over 10 hours of data with my mono-converted Canon 60D, iExos-100, Rokinon 135mm f/2 lens, and Astronomik 6nm H-a clip filter.

I did a drizzle integration in APP and then brought it into StarTools for some sharpening, deconvolution, star reduction, and noise reduction. Then back into APP for stretching, and GIMP for final adjustments. Last I did a slight color shift to give it an antique-ish sepia look.

I'm usually not a fan of how StarTools stretches the data, but it did a really nice job of sharpening and deconvolution. The effect was subtle but brought some of the details of the nebula into sharper view.

As always, C&C welcome and appreciated!

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.
