M20 the Trifid Nebula in Sagittarius

I didn't intend on imaging this object. I wanted to image IC 4592 the Blue Horsehead Nebula.

However it was located in very heavy light pollution. IC 4592 is a very dim object. I tried

several different iso settings and exposures just to see if I could capture any nebulosity. I

could not see any nebulosity and most of my test images were blown out because of light pollution. So rather than waste a clear sky night I decided to image M20. I was using my

AT72ED Refractor to try and image IC 4592 so I also used it to image M20. When I finished imaging M20 with my AT72ED Refractor I went inside and brought out my AT6RC and swapped out the scopes. So I imaged M20 last with both my AT72ED and my AT6RC.

Description: Due to the weather I've not been able to get outside and image. So I was looking over some of my image folders and noticed this image. I decided to completely reprocess the image beginning with aligning and stacking. I like to get the practice processing even if I can't image.

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.
