M13 - Bortle 9+ - lucky imaging - short integration

Acquisition type: Lucky imaging

My photography possibilities are, as I always write, very limited both due to the sky from which I work (a Bortle 9+ with very high humidity and lighting) and because I work with the lucky imaging system and I can make poses with a total integration time limited to no more than approximately 60-90 minutes. In these conditions there are few subjects within my reach and so, to start working again with the 125 f 7.8 apochromatic refractor and the ASI 183mm camera, I chose an easy subject, the globular cluster M13 in Hercules.As usual, no significant post processing was carried out except to insert the writing and slightly adjust the dominant sky background.As always, to give objective feedback to the images, the field of view has a pre-set value and equal to 40'x40'. Te visibile SPIKES are REAL and obtained with a cross made with a 3mm. adhesive tape in front of the lens. Some peculiar data regarding the star are indicated at the bottom of image.
Here is last night's image with poses and features as follows:

Tecnosky 125 APO f 7.8 OWL

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.
