Helix Nebula - (NGC 7293)

The Helix Nebula (NGC 7293) in the constellation of Aquarius, from 3 nights of imaging last week in Melbourne just after new moon. It certainly helps when the DSO (in this case a planetary nebula which are the remains of an exploded star) is high in the sky. No guiding and no darks/flats/biases applied to this one at this point - just stacked lights.

The outer rings of this still exploding star are quite faint though, so another 4 hours of gathering photons should bring them out. But am very happy with the depth of colour in this processed rendition, it should glow well when printed on aluminium. I have imaged this with RGB (Red, Green, Blue) filters on the front of the cooled CMOS sensor, so this is a true-colour image. Best viewed when brightness on your phone is maxed out.

Luminance: 240x30secs (2 hours) - Bin1x1 T-20C Gain 200

Red: 80x30secs (40mins) - Bin 2x2 T-20C Gain200

Green: 80x30secs (40mins) - Bin 2x2 T-20C Gain200

Blue: 80x30secs (40mins) - Bin 2x2 T-20C Gain200

Total Exposure 4 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.
