NGC7662 - Blue Snowball Nebula

This was one of the first objects my son and I observed when we got our CGEM / 8" scope a few years ago, and I have always wanted to try to image it. It is a difficult nebula to get detail on because it is so small (37"), and a full moon doesn't help. Also, the ring in the middle is bright, which requires short exposures. This was shot at 2800 mm because of size and I did 300 x 30 second luminous frames, but used less than half of them. This was combined with 40 minutes each of R, G and B. All binned 1x1. The inset is an enlargement of the nebula at the center of the image. The second inset, to the right, is a Hubble image of the same object. To get as much detail as possible, I performed a combination of up-sampling and deconvolution in PixInsight. Other than the full moon, the sky was good and calm. Guiding ran between 0.35" and 0.45" RMS the whole night.

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.
