The Ghost of Cassiopeia (Sh2-185, IC63) HaRGB

I first imaged some Ha of this area at the end of October and quickly realised it was going to need RGB to give it that natural reflection & emission colour. It took a while but earlier in the week I managed to get some LRGB - unfortunately I didn't use the L and the B subs got cut short with clouds!

I'd have hung out for more RGB another day but the RedCat's FL is struggling to do this justice. With that in mind I set about creating an HaRGB image - without the Ha this would have been consigned to the "for a rainy day" pile. Thankfully, I think the strong central Ha structure and very faint Ha swirling around in the background has helped bring this image to life and - for me - the expansive star field is enjoyable too.

The main image above look quite soft before mouse over, definitely worth opening in new tabs. Thanks for looking.

This was captured with Voyager, calibrated & stacked in APP then processed in PixInsight.

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.
