M13 with the Stellarvue SVSX 130MM f/5 astrograph. Just over 2 hours at 655mm. I offset M13 somewhat from center in order to get the cluster of small NGC galaxies located to the right of the image.

I was told there is a feature in M13 called "The Propeller" that is not always captured. when I looked at the image I was able to see it clearly. CN confirmed its there. Bordering the brightest part of the core of M13 at about the 7:00 position there is a Y shaped dark feature. I was able to find out more on the internet about it as well.

With 4x the exposure, it's easy to see the difference over the pervious version I have posted on here with only 30min exposure.

ZWO2600MC @ 100gain. 248 x 30" subs, 20 darks. No flat or bias

RMS .5 - .8 arc/sec guiding

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.
