Perseus Double Cluster - NGC884 NGC869

The Double Cluster in Perseus - NGC884 (top) and NGC869 (bottom).
Two open clusters about 7.6K LY away, 14 million years old.
Naked eye visible as a grey smudge and sparkly in binoculars.

I imaged this with a 61mm scope a couple of years ago and included lots of Ha (too much), so this go-round with the 102mm scope I captured no Ha subs. Since there seems to be such abundant surrounding Ha, the broadband 6nm red filter picked up sufficient Ha, that I opted to include some of the red ‘continuum’. The dull brick red helps to offset the image's old red and younger bright blue giants.

Imaged over two windy evenings, omitted a number of subs due to gusts. The fact that round stars are still possible is in large part due to the quality of the processing software.

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.
