The Majestic Elephant Trunk Nebula

This is the first SHO image I shot using RGB Stars. I've seen a number of processes where people described adding RGB stars to SHO images. I didn't do anything special other than combining the RGB channels, extracting the stars and adding them to the starless SHO image. I definitely like the added color of the RGB stars.

On another note, I had to toss a number of the RGB star subs because of focus issues. I typically use the multi-star FWHM auto focus routine in Sharpcap. As of late, I've been having an issue with it not working. It will run through the focus routine and I notice the starting point will jump and when it tells me the focus is complete, I can see the stars are small doughnuts. I've realized I need to pay close attention when I run the focus routine. I'm wondering if anyone else has similar issues with Sharpcap.

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.
