I have planned this Cepheus project for a long time. Finally I have been able to finalize it. I have done some large mosaic images of nebula rich areas in our Milky way. The ultra fast camera optics, Canon EF 200mm f1.8, it's a perfect tool for the job. It has a large, flat and sharp, image field and full open at f1.8, it collects photons very fast. The final image covers an area of about 18x10 degrees. (Full Moon has an apparent size about 0,5 degrees. 720 full Moons are needed to cover this area in the sky.)

This narrowband image is shot with QHY9 (a cooled astronomical camera), Canon EF 200mm f1.8 camera optics full open, Baader Planetarium Narrowband filter set for an emission of ionized elements, Hydrogen, Oxygen and Sulfur. (H-alpha, O-III and S-III) The dimensions of the final mosaic image are 12000 x 6500 pixels.

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.
