Trifid Nebula in HaRGB

----------------------

The Trifid Nebula is a region which consists of a bright emission nebula (red) and a faint reflection nebula (blue) surrounding a star cluster.

The red part of the nebula is caused by the absorption & re-emission of the stars' radiation by hydrogen gas.

The blue part of the nebula is caused by the same radiation being reflected/scattered by faint interstellar dust.

The dark areas throughout the nebula are created by opaque/dense interstellar dust blocking this radiation.

This image was created by combining 8 hours of Hydrogen-alpha & 8.5 hours of colour data I collected in May & June 2020.

----------------------

Total imaging time: 16.5 hours (8 hours in H-alpha + 8.5 hours in color)

Telescope: Sky-Watcher Evostar ED100 Black Diamond

Camera: ZWO ASI294MC Pro

Mount: AZ-EQ6 Pro

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.
