Between the cloud and the job it's been a while since I found time for image capturing and processing - it's great to be able to get back to it.

This is the result of using the fantastic Generalized Hyperbolic Stretch (GHS) tool by David Payne and Mike Cranfield. GHS takes some of the guesswork out of stretching - I'm looking forward to spending a bit more time figuring out how to use it.

Description: Reprocessed using
- 2x Drizzle Integration
- SpectrophotometricColourCalibration
- BlurXterminator
- NoiseXterminator
- Binned 2x2
resulting in (I think) better colour rendition, more detail in the galaxy and smaller stars.

resulting in (I think) better colour rendition, more detail in the galaxy and smaller stars. A little less contrast than the previous revision.

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.
