First attempt at the Eagle Nebula, and the first real imaging session this fall. Also, this was the first time I used LTI on my SkyFusion. Its a new-ish interface for imaging without guiding, and..it dithers!! I used a setting of 12 arcsec dithering, since the recommendation is to do ~6x your seeing. The best FWHM measurement I got in the focusing routine (@focus3) was right around 2 arcsec. This was also my first time imaging with the ZWO ASI183-Pro and the new ZWO EFW (7-position, 36mm filters). All in all I'm pretty happy, though I can see some ever-so-slightly mis-shaped stars, which I think is a result of either tilt or a little tuning needed during focusing. I ran the data through the new WBPP in PI, and used the excellent icon set provided by Masters of PixInsight during their series of PI Intro workshops last year. Finally I finished it up with the EZProcessing Suite EZ Star Reduction. The main image is using the Adam Block method, the alternate is using the Morphological Transform method.

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.
