M27 - Dumbbell Nebula / Apple Core Nebula RGB/OIII

This is a multiple session image consisting of 75 - 60sec and 45 - 90sec subs for a total integration time of 2.5 hours. Its been difficult trying to gather the data with the heat, humidity and smoke from the wildfires here not to mention very wet conditions all adding up to VERY low transparency. None the less this is what I've been able to do with the data.

This is my 1st image using a new setup consisting of my (both new to me) 10" f5 newt and ZWO ASI071MC Pro with an IDAS NBZ filter in the mix. I processed the data in APP with the HA/OIII Color processing then I used the "extract" the OIII channel combining them into one using the "combine RGB" feature in APP's Tools tab.

Final post processing was done in Gimp using some of my favorite plugins like "G-Mic & Py-Astro" to name a couple.

I really was hoping to pull the OIII bubble out better around the nebula but the transparency just killed me here.

I have another image of 45min integration with my 8” of the same object with the same filter. Effective FL for the image with the 8” = 1000mm and the 10” = 1200mm

Bortle 4.2
Seeing 3.5 / 5
Transparency 2 - 2.5 / 5

Thanks for looking!

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.
