Sh2-123 The Tick Nebula "One Tough little Bug!"

SH2-123 (Sharpless 123 ) The Tick Nebula

This nebula is on the faint side, so it needs quite a bit of exposure time to capture some of
the detail and structure. A wider field of view will pick up the outer area of SH2-118 but this is even
fainter than Sh2-123.  The nebula picks up fairly well with a hydrogen-alpha filter, but RGB color
is weak and very difficult.  I Imaged Sh2-123 multiple nights from 9/13 -9/26. It is approximately
12,000 light-years distance and is also sometimes called "The Flea Nebula".

Note: If you're wondering why 19 hours 40 minutes integration time why not 20 hours! Well,
my goal was 20 hours +. I was imaging the last good dark night before Tropical Storm
Ian came in. At around midnight the clouds came in and I thought good enough!

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.
