After struggling several nights with malfunctioning devices, in freezing -20 celsius wind, I managed to collect enough data to finalize my Melotte 15 project. (I did lost skin from my finger tips, while fixing various problems out there...)

There are much large images in my blog and there is a panoramic, two frame, mosaic of this area as well. Be sure to click the images to see them full screen! Total exposures for H-alpha 45x1200s = 15h

The open cluster centered in this image is known as Melotte 15 . Melotte 15 is embedded within a central portion of the much larger glowing nebula identified as IC 1805.

The interesting structure in the center of the image is a giant area of hydrogen gas that is caused to glow by the intense ultraviolet radiation from the massive stars of the Melotte 15 star cluster.

Dust and gas clouds are twisted by the pressure of the intense radiation, the solar wind.

This formation is estimated to be 7,500 light years away from Earth, North is up.

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.
