M76, NGC 650 Little Dumbbell Nebula

This is a bipolar planetary nebula in Perseus imaged during November 2020 at a suburban location.

Main image acquired in narrowband Ha and OIII with stars imaged in RGB. Basic processing fairly straightforward in Pixinsight to obtain Ha, OIII and R, G, B masters. Narrowband starless tone maps were then obtained using Starnet in Pixinsight. These were processed to reduce noise and made non-linear using ArcsineStretch and combined into a master narrowband master with PixelMath -- Red:Ha, Green: OIII plus some Ha, Blue

III. The NB master was further processed to enhance structures and sharpen.

RGB channels processed and combined using a standard workflow. Stars were then extracted using Starnet and added to the starless NB master using Pixelmath. Some final adjustments using CurvesTransformation and Apple Photos editor.

Subframes selected were:

Ha 78x600s

OIII 62x600s

R 74x180s

G 77x180s

B 53x180s

Total integration time was therefore 23.3 hours for NB and 10.2 hours for RGB stars, a total of 33.5 hours.

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.
