Barnard 150, Seahorse Nebula

I had a go at this last year, and wanted to try again to get some better detail in the dusty background and also to utilise my improved tilt and backfocus to produce some slightly better stars.

I've struggled to get the balance in this one, not helped by calibration issues with my monitor (or at least Windows 11 failing to keep the calibration profile active for more than a few seconds). Not sure if this is too bright right now, but I'll come back to it if necessary. Also I need to work out why my background seems a bit on the purple side. This happens to me fairly regularly, not sure why, perhaps I need to scale back on the green noise removal.

Second revision is a slight adjustment to try and correct this, with a shout out for Jon Rista's Pixinsight articles - only place I've seen a proper explanation of how to apply SCNR in a controlled manner! (I'll go back and re-process this properly at some point)

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.
