Double Cluster NGC 869 and NGC 884 L+OSC RASA8

The Double Cluster is one of my favorite objects to look at through my 9.25 SCT. It's looks like two diamonds merging in a jewel box.

This capture was an experiment in in taking good sampling Luminance data with unlocked 1x1 binning of the ASI 294 MM at 2.3 um pixel size and upscaling the color data to match from a 4.6 um with ASI 294 MC.

Only 1 hr 10 min of integration time, I am pleased with the result and like the resolution gained with the luminance data especially to crop in on the clusters themselves.

The double cluster is a combination of two open clusters in the constellation of Perseus. NGC 884 (3.2 million years) is thought to be young than NGC 869 (5.6 million years) which is more compressed. Both clusters are an estimated 7,000 light years from earth, each is approximately a few hundred light years from the other.

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.
