Picture Details: Dumbbell Nebula (aka the Apple Core Nebula) (M27/NGC6853) is a planetary nebula in the constellation Vulpecula. The nebula is ~1360 light years from Earth and is the first nebula discovered by Charles Messier (in 1764).

My setup:
Mount: EQ6R-ProTelescope:
Williams Optics 81 mm Zenithstar doublet
ZWO-ASI224MC color camera for guiding with the Zenithstar guide
Hotech Corporation 2” Field Flattener
ZWO ASI2600MC Pro; Camera cooled to -10 deg C, with ZWO Duo-Band Narrowband Light Pollution Reduction Filter
Bortle-9 – South Los Angeles shot from my backyard

Integration Time: 2 Hours 48 Minutes; Lights (41 @ 180 seconds); Darks (26 @ 180 seconds); Flats (25); Bias (25)Image

Processing: PixinsightUsing lessons from multiple great resources from Youtube: Mitch and his 12 part Pixinsight series/workflow (https://youtube.com/playlist?list=PL6_eBQy3QM7xISY4Gdz-MmH4rA_1WAG2d) and Late Night Astronomy (https://youtu.be/CZSVCNX8Ow8). Additionally, I used some help hints from Chaotic Nebula and his workflow (Chaotic Nebula - Your guide to astrophotography)

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.
