Brain on fire

This Brain-like nebula or Crescent nebula NGC 6888, is emission nebula about 5000 light years from Earth. Its located in Cygnus constellation. The nebula is an expanding shell of gases results from Wolf-Rayet star in the centre of the nebula. This hot powerful star produces a fast speed solar winds that collide with the older outer shell gases. The impact is energize and ionize the outer shell gases to glow up in Hydrogen and Oxygen emission lines (Red & Blue in colour respectively). Captured over 2 nights in HOO palette with total integration of 4hrs & 20min. Gear setup: ES 100 APO CF, iOptron GEM45 guided by ZWO mini guidescope and ZWO ASI120MM-S, EFW 5x1.25, Baader Ha 6.5nm & O iii 6.5nm filters, ZWO ASI1600MM pro cooled @ 0, Gain 100. Acquisition by APT, Stacked by DSS and processed by PS.

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.
