Saturn Nebula (Caldwell 55 / NGC7009)

Caldwell 55, also known as the Saturn Nebula and NGC 7009 is a planetary nebula located in the constellation Aquarius at a distance of cca 5000 LY. It is very small nebula and has a faint resemblance to the planet Saturn with rings nearly edge-on

NASA describes it "While it looks like a piece of wrapped cosmic candy, what we see is actually the outer gaseous layers of a dying star."

Given its size, it is a challenge with my 4 inch scope to bring out any real detail - a mix of the 294MC and 294MM (with O3 filter) has picked up major features. Also due to its brightness, only Arcsinh was able to bring out the nebula without blowing the core (no real joy using MaskedStretch or Histogram Stretch).

Description: Reprocessed on combination of channels, and multiple stretches using different masks and several HDR Multiscale Transformation te bring out the core more delicately. Not an easy target for a 4 inch scope.... but an enjoyable one.

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.
