SH2-296 The Seagull Nebula

Revision title: Alternative Color Edit

This is the first light of my new scope, a fast wide field Sharpstar Hypergraph which replaces my RedCat51 setup. I found the RedCat with it's focal ratio of f/4.9 a bit slow in combination with narrowband imaging, so I hope the new setup will do better at f/2.8. Unfortunately, because of the bandshift involved in narrowband imaging, I had to retire the very good 3nm Optolong L-Ultimate filter and replaced it with the (at that time) only available high-speed dual narrowband filter - the Antlia 5nm ALP-T Highspeed. I was very curious how the new filter will perform, so it was clear that the first target will be an emission nebula.

After a couple weeks of waiting, a single clear night gave me the opportunity to run the new setup. I spent the first hours of the night on dialing in tilt and backfocus, but it was freezing cold so I stopped it at some point and used the rest of the night for imaging.

Postprocessing of the data was challenging as the data quality was not great. The weather was dusty, the object was low on the sky and tilt and backfocus were not fully dialed in. Thanks to the modern processing tools most of the issues could be addressed by software. Hope you enjoy the image!

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.
