M22 Globular Cluster in Sagitarius. This is another of a series of EAA image trials taken during my migration over to EAA. Equipment used was my ED150DX, reduced, ASI294MC (noncooled) camera, and my CGX mount, all located in my backyard observatory in NSW Australia. Shaprcap 3.2 was used to manage the process, aligning and live stacking the frames (or subs if you prefer) as we went along. This image consists of just 9 x 30s frames. Minimal tweaking of the historgram was done in Sharpcap, no other processing software was used.

I would like to point out that EAA is not a replacement for traditiona long sub imaging, but is ideal for time poor folks, or those of us that can no longer do long sub imaging due to poor eyesight, or health problems. As an adjunct to visual astronomy it give the user much more reach than our simple eyesight can provide.

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.
