Ellis, Grayson, Bond 6 (EGB 6) is a very old and extremely faint planetary nebula in the constellation Leo. It has the distinction of being one of the faintest planetary nebula known. It was discovered by Howard Bond back in 1984 by looking at Palomar Sky Survey prints where he noticed a smudge in the corner. Later, spectra made at Kitt Peak would show the star had strong OIII emission. In his words, "this began the story of EGB 6 ". EGB 6 measures 11x13 arc minutes. Short RGB exposures show nothing here. Only by taking long Ha and OIII exposures was the PN revealed. The central star is a white dwarf (WD0950+139) with a temperature of about 100,000K. It was found by HST to actually be a binary and and several interesting papers have been written about just this star. The image is the result of roughly 6 hrs of RGB images, 27.3hrs of Ha and 30hrs of OIII for a total exposure time of over 64hrs. Red was mapped to Ha and OIII was mapped to Blue and Green. It took me two seasons to get all the data. I started in February 2022 and finished in February 2023. The image was taken using 1x1 binning with a resolution of .64 arc sec/pixel.

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.
