M13 with my big scope

To pair with my unguided M13 image from I took with my 5.1" scope, I thought I would also include the same target shot with my 16". Granted the 5.1" exposure was only 270 seconds total integration time, while this one is 443 seconds. But aperture still rules, even on a level playing field, getting more stars and more detail.

Description: Minor contrast adjustment to fix lost halo stars and a bit of sharpening to make them more obvious.

Description: Reprocessed with Fitswork to better maintain star color and get better black and white balance (on a field star).

E

Description: This has been bugging me, so I did some further processing to better hold color across the cluster and background stars and fix some vignetting I forgot to repair. I also sharpened the stars some more, which actually made the outskirts look dimmer, but its just that the stars are sharper.

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.
