The Wizard Nebula in Cepheus. SHO tone mapped

A tone mapped image of the Wizard Nebula in Cepheus. The area is full of stars which can easily run amok and take over the image. By using a tone mapping process the stars are removed and added back at the end. So you gain a little control over their size.

Another plus is you get to play with the colours, as the narrow band spectrum is out of our eyes visible range.

Only the six or, seventh image I've tried to tone map. Having only processed one other image in the last six months, there's nothing like a challenge to get you back into Pixinsight again. Needless to say this is over 12 hours processing, plus many deleted attempts :-)

Still the stars are looking ok.

Description: E: This is a SHO version using a formula by ForaxX which can be found on his website https://thecoldestnights.com/2020/06/...
I like the resulting palette. I used my tone mapped data with an enhanced Lum. You have to stretch the 3 filters before combining using the formula.

Description: Old data reprocessed using all the RC Astro's gizmo's. removing the stars has really helped me control them better as with this fov they took over the image. Doing the first stretch with Arcsinh Stretch helps me with the colours without over saturating the image as well.

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.
