I'm in the process of creating my first planned mosaic, the Heart Nebula. I used SGPro's Mosaic and Framing Wizard, but because I chose a non-orthogonal angle and my Hyperstar flips the images, the angle the wizard gave me was wrong. Here are the details. In order to do something with the data I had already captured, I decided to crop the center and process it, and here it is.

This section of the sky has a good balance of Sii, Ha, and Oiii. When I combined the channels to get the color image, I had to do very little tweaking to get the colors to my liking. Usually I have to fiddle a lot to pop the blues and tame the greens, but this one was very well balanced to start.

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.
