NGC 7293 "The Helix Nebula"

NGC 7293 "The Helix Nebula" is the largest planetary nebula (PN) as seen from earth, located in the constellation Aquarius. This object is the closest to the Earth of all the bright planetary nebulae.The estimated distance is about 700 light-years away, spanning about 2.5 light-years. The age is estimated to be 10,600 years. The Helix Nebula has sometimes been referred to as the "Eye of God" as well as the "Eye of Sauron".

This planetary nebula is probably the best in the sky as it is quite large although dim that could show lots of details. Unfortunately, the best time this object is in the sky is in rainy season to early winter in Thailand that the sky is normally cloudy and humid. By the time the sky is clear, the object is already too low in the sky. Because of this, I did not have much time to correct its lights during each imaging session thus the images I got so far had very weak signals. To create this image, I decide to use all of my available data, 3 imaging sessions, going back as far as 2003. The equipment that I used to capture its lights vary from low to high resolution as follows :-

24 Nov 2003 SBIG ST-10XME, Takahashi FSQ-106 at 530 mm f/5, Losmandy G-11 from Phuhin Rongkla

14-15 Dec 2009 SBIG ST-10XME, Takahashi TOA-130, 1,000 mm f/7.7, Astro-physics 900 GTO from Phuhin Rongkla

22 November 2014 SBIG STT-8300, Takahashi CCA-250, 1,250 mm f/5, Astro-physics 1200 GTO from Pakchong Nakornratchasima

All together, the combined image has a total exposure of 242 minutes or roughly 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.
