Kronberger 24 (Kn 24) HOO With RGB Stars

Planetary nebula are a favorite of mine for imaging. Astrobin is a great way to learn about new targets and when I saw @Sven Eklund’s image of Kn 24, I decided to give it a whirl since his image (link attached) is so striking.

As I learned more about this target, I knew it was going to be a challenge as it is so rarely imaged (I believe mine makes the 6th image posted to Astrobin). Sven’s image includes some nice background Ha nebulosity which mostly eluded me. That wasn’t surprising as my EdgeHD 8 doesn’t collect nearly as much light as his EdgeHD 14 with Hyperstar.

I decided to use a combination of 1000 second exposures with long integration times to compensate for the shortfall in aperture and focal ratio. All in all, I was pleasantly surprised at how well the EdgeHD 8 did on the primary target.

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.
