M22 and environment

M22 is a famous GC in Saggitarius. The diameter is about 32 arcmin which is bigger than M13 in Hercules which spans only 20 arcmin.
With an altitude of -24 deg I do have only a window between a hill and some trees of max 2 hrs. exposure time. With my double setup the lower scope is already very close above the outside wall, even so that a part of the wall can be flipped down to have better horizon look. -25 deg is the lowest possible view for me from home.
Last weekend the weather forecast was mixed. Surprisingly clear sky was out in the evening. I took 2 hrs of exposure, but only 1 was without clouds.
Hope you can still enjoy the picture!

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.
