HFG1, Abell 6 and Sh2-196 - three PNs in one frame

Here I caught three planetary nebulae in one frame just north of the Soul and Heart nebulae, using my dual-RASA rig. Looking through Astrobin I find that they are rarely (never?) imaged together. Of course their small size make each of them more suitable for longer focal lengths, but there are plenty of such images.

From left to right the PNs are Heckathorn-Fesen-Gull 1 (HFG1) which is around 10 000 years old. Then comes the bubble-shaped blue planetary nebula Abell 6, which is faint (Mag = 15) and clearly emits more in OIII than in Ha. Finally, there is the strongly Ha emitting Sh2-196, which is rarely mentioned but often caught together with the Heart and Soul nebulae in wide-field images.

No filter used so the ASI2600MC is quite good at picking up Oiii and Ha with a light bucket as the RASA 8 and a dark sky. But a major problem was the strong star field, and I had to stretch the nebulosity on a starless image (Star Xterminator in PS) before I brought the stars back.

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.
