The Blue Horsehead Nebula, IC 4592

This is my first imaging session with the iOptron HEM15. I shot this over two nights, getting about 6.5 hrs of integration. I managed to get two nights without much or any smoke in my relatively dark skies on the shore of L. Erie. Processed in PixInsight, using WBPP followed by drizzle integration, DBE, SPCC, BXT, NXT and SXT, stretched with HTF (GHS wasn't getting me the results I liked), CurvesTransformation, increased saturation with some masking, several applications at different scales of LocalHistogramTransformation, and a touch of star reduction.

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.
