NGC6960 The Witch's Broom

NGC6960 The Witch's Broom imaged through my Esprit 150/SX-46 with piggybacked Esprit 100/ASI1600mm on a Mesu 200 in early September 2019. Ha and RGB through the 150 and Ha and Oiii through the 100 as follows Esprit 150 2.5hrs R, 1.7hrs G, 1.5 hrs B Esprit 100 9hrs Ha, 6hrs Oiii total 29hrs.

Processed in Pixinsight and Photoshop, in particular I used StarNet to produce starless narrowband images which I then blended with the starry ones and layered over the R G and B in photoshop using blend mode lighten, Ha to Red at 100%, Oiii added to Blue at 100% and to Green at 50%. RGB was processed using Pixinsights HSVrep process then ArcSin.

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.
