Melotte 15 (Heart of the "Heart Nebula") (Daniele Malleo)

Melotte 15 (Heart of the "Heart Nebula")

A weather front has arrived form the pacific Northwest, which means no more imaging for at least three night.

So I got tired of waiting and just used the data I had:

Exposures so far:

- 25 x 30m subs in Ha (5nm)

- 20 x 30m subs in OIII (3nm)

- 10 x 30m subs in SII

(3nm)

total exposure time: 27.5 hours.

In this rendition, I have mapped SII To Red, Ha to Green and OIII to Blue. I have then extensively tweaked the hue and a/b ratios in L-ab mode to get a yellow/red over blue color scheme.

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.
