NGC6888 - The Crescent Nebula - With and without stars

This is always a favorite of mine. I shot this about a year ago with my Redcat 51 setup. It always amazes me the ridiculous number of background stars around this nebula. While I am more than a purist at heart and I tend to not use plugins like StarXTerminator for anything other than reducing the green tinge we all get on our stars due to excessive green almost all OSC cameras suffer. That being said, in the case of NGC6888 especially I will make an exception, as the detail in the central gas clouds with even my little Vixen telescope, there is an amazing amount of detail. My initial image will have stars and my second image will have the stars removed so one can view the detail in the central core.

Title: NGC6888 - No stars

Description: This is the nebula with the stars removed. On my original with stars, even with the cropped image the plate solver in PI stated that there were 19,431 stars. Thats just crazy. The details with the stars removed amaze me that a simple 4" refractor can obtain this much detail. Now imaging in Bortle 1 skies does help for sure.

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.
