SH2-170

SH2-170, the Little Rosette Nebula, is in an H2 region of the constellation Cassiopeia. - some 7500 light years away. This is an SHO image with significant amounts of overlapping Ha and Sll. The blue central region is Olll. The overlapping HA and Sll presented some challenges in pulling out color variations, so I experimented with several different palettes befor setteling on this fairly straight forward SHO with the application of the "Selective Color Correction Script" in the GraXpert Toolbox. I liked that it it offered a lot of different masks and colors but the real time preview is misleading because the actual application of the script came out much stronger than was shown in the preview. However, I think they are onto something but really need to improve the real time preview. I think the "Improve Brilliance" script in the toolbox also has potential but I ended up not using it for the same reason - again the real time preview was not accurate. I found that it was easier to use LHE and MNT because you could see what you were doing. Still, if they correct the preview problems, it could be a very useful tool.

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.
