Melotte 15 LRGB

This is why I wanted to get the 9.25HD! The heart of the Heart...an amazing area. Melotte 15 is actually the open cluster of bright stars which light up, ionize, the gasses. I've read that many of these stars are 50 times the mass of our sun.

Imaged from a dark site on the east side of the Sierra's near White Mountain. It was the darkest site I've ever been in. The Milky Way was visible before true darkness. Sadly it was smoky and heartbreaking to think the smoke was from the Sequoia Redwoods. I managed to take enough good enough images over 3 nights. 1x1 binning. Stars where bloated, assuming from the poor seeing due to smoke. This is an RGB image with Ha used as luminance, which greatly reduce the bloated stars, but reduced their color. Oh well. I used only a slight Topaz noise reduction setting of 5 with zero sharpening. I do have some Oiii data and hope to process in HOO.

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.
