NGC 6811 the Hole in Cluster

Before I went outside tonight I decided that I would try and image NGC 6811 an open cluster.

I felt that it would be less affected by the Moon than some other objects. I decided to use

my Astro-Tech AT72ED Refractor. I actually bought this scope because I thought it would perform well on open star clusters. So far it has done a good job with open clusters. I have confidence in the scope and it is a good fit for me. With all of that said please enjoy my first image of

NGC 6811 the Hole in Cluster.

Description: It never fails. My image looked fine on my monitor.
However when I uploaded it to Astrobin the light
gradients were obvious. I reprocessed the image to flatten the background a little and remove gradients.

Description: When I looked at my image with fresh eyes this morning there were some things that I didn't like. I reprocessed the image to clean it up a little and flatten the background a little more.

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.
