Sh2-207 & Sh2-208 HaRGB

I continue my hunt for interesting objects in the Sharpless catalogue. Here are two of them, the bigger one in the centre is Sh2-207 and the smaller one to the left is Sh2-208. The small star cluster seen in Sh2-207 is Mayer 2. The big area of nebulosity covering the left side of the image has as far as I know no number or name, possibly becasue it is very faint. Still it has some nice structures. Almost all the red signal was picked up by the Ha filter and there is only a faint indication of Sh2-207 in the RGB data. Sh2-207 was once thought to be a planetary nebula, given the designation PK 151+02 1, but this is probably not the case. These nebulae are 13 000 - 15 000 ly away

Ha was collected over two clear nights (SQM 21.3) with the Esprit 100 and ASI1600 (40 x 15 min at gain 139) and RGB with the Esprit 150 and ASI071 (125 x 5 min, gain 200), sitting side by side on the Mesu 200.

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.
