Cosmic Bubbles : Heckathorn-Fesen-Gull 1 - HFG1 & Abell 6Located in Cassiopeia, probably one of the dimmest nebulae I've imaged.
Overall, some 40 hours of data was used, a lot of subs were removed due to low SNR. HFG1 is a planetary nebula in Cassiopeia. The estimated 10,000 year old nebula has a very dim blue-green leading bow shock with a tail on the opposing side. The smaller Abell 6 is another dim planetary nebula. It consists of more Oiii than H-alpha, hence the prominent bluish white color.
The Telescope:
The faster optical setup of the CDK14 at f/4.7 and the 3nm narrowband filters were useful to increase the FOV and increase the image brightness that helped overcome noise. I would have preferred more Oiii data but the number of clear nights are very limited now.

Shown here is Ha-OO mapped to RGB with a slightly modified expression:

R: Ha
G: ((Oiii*Ha)^~(Oiii*Ha))*Ha + ~((Oiii*Ha)^~(Oiii*Ha))*Oiii
B: Oiii

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.
