NGC 7293, The Helix Nebula

The Helix Nebula (NGC 7293), the iconic planetary nebula in the constellation Aquarius. The image is a combination of the narrow-band (H-alpha and OIII) and RGB data taken with the 250mm f/4 Lacerta PhotoNewton and ZWO ASI294MM Pro camera over several nights in September 2023. NGC 7293 was a tough target to both image and process, considering its low position in the sky (33 degrees maximum elevation) and mediocre seeing conditions.

The synthetic luminance was produced using H-alpha, OIII and RGB star data. R color channel is a blend of the broadband and narrowband images (R and H-alpha). B channel image is a blend of OIII, H-alpha (to simulate H-beta contribution) and B bands. The narrowband exposures were taken with camera gain 200 and 300. The RGB data was captured at gain 108.

Exposure Details:
Ha: 10x600s (Gain 200, bin 1x1), 17x300s (Gain 300, bin 1x1)
OIII: 21x600s (Gain 200, bin 1x1)
R: 20x180s (Gain 108, bin 1x1)
G: 10x180s (Gain 108, bin 1x1)
B: 10x180s (Gain 108, bin 1x1)

Total exposure time: 8.6 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.
