Cepheus-Cygnus 32 panel megamosaic.

Yves Van den Broek captured these 32 panels with his remote setup, which I host at Les Granges. (Tak FSQ106 reduced, Mesu 200, Full Frame QHY CMOS OSC camera.) He also put the panels together in APP. This produced a good template but a very unsatisfactory blend. Yves then handed me the template and the raw files. I slightly altered the geometry of the template to reduce final cropping and then processed the original subs in PI and Photoshop, using a recorded initial stretch action for consistency and speed. I used Registar to build up these subs onto the template. Further stretching was done to the whole image in Ps. The Squid Nebula and one or two other details came from my existing data, calibrated in Registar and blended in Ps. Great fun. This processig took about a working week, including the inevitable false starts!

So... lots going on in Cepheus. It's not great for the visual observers but you can see why we imagers love it.

A big thanks to Yves for giving me the chance to get involved in another very large mosaic. I was knocked out by the camera. I've never been an OSC fan till this time. There are no Ha filtered subs in this.

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.
