Const. Cygnus project - Mosaic image with 44 panels

Having see the picture of the day of a couple of days ago, I wish congratulate the imager for taking such a task. I did the same a few year ago and here is the cropped version of my mosaic.

This wa a project I had been working on for a long time. This mosaic image involves 44 large wide-field images (4000x2700 pixels each) some of which go back to 2011. Most of the remaining images were taken over a period of 2 months in 2013, with 150 hours of Halpha data, using a TAK FSQ 106 ED telescope with an SBIG STL 11000 ccd + .73 TAK focal reducer on a TAK EM11 mount. Since this is an extremely large image, it had to be reduced for uploading on this site. Area of the sky is about 23x23 degrees. The Moon has an angular diameter of 0,5 degrees, it fits to the area of this image about 2116 times. Some of the well known objects in this image comprise of the Veil nebula (NGC 6960, NGC 6979, NGC 6992, and NGC 6995), N.America (NGC 7000) and the Pelican nebula (IC 5067 & IC 5070), the Crescent nebula (NGC 6888), the Butterfly nebula (IC 1318) , the propeller nebula (DWB 111) and the Tulip nebula (Sh2-101). For detail, enlarge the image to full scale. Processing this image, trying to blend each image with those next to it, was very painstaking. But the resulting image makes all the work worth it in the end. Locality APO-LEN-DI observatories - Malta.

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.
