Poor man's Abell 6 and HFG1

Tried a little fainter object to image, and well, so far it stays as a try. The Hα data were taken when the seeing was not incredibly good, the OIII data though had a perfect weather setup for Northern Florida, right after a cold front swept through and left us with very dry air, the equipment was not even wet with a single drop in the morning! Still ... these are 2 tough objects, really faint in OIII, but even fainter in Hα! Tried to squeeze out the best I could, details are still barely visible. Next clear night I might try 10 minute exposures, especially some Hα data, let's see if this will help. In the meantime I wanted to post this version since it should also tell the story how difficult some targets really are. And with that on your mind please visit the image by Jerry Macon (https://www.astrobin.com/394808) or by Big Dipper (https://www.astrobin.com/369293) ... these are indeed images of the day!!

Description: Thank you Johny for making me aware of stupidity 😅 (replaced version C)! At least I saw that the 600 second images were much noisier, should have marked it that way as well. I hoped for a bit more nebula features with the 600 seconds, but it looks like that it does not work that easy. I compared the images in PixInsight again and the differences are by far not as significant as see here with the combined images done with IrfanView. I still will take the new data and see if I can improve the overall image.

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.
