M42 Orion Nebula is a typical northern hemisphere target along Orion's Belt, since it is used as a "benchmark" test of equipment since it is a nebula with a lot of dynamic range.

The data here is from two back-to-back evenings, but did involve different sets of flats. This is my first successful image using OAG (Off Axis Guiding). Although I am using a smaller ED80 scope, I did use the larger CGEM-DX mount. I was only doing 60 second exposure, where guiding shouldn't really be necessary with a decent mount, but it was a good practice (plus PHD performs Dithering). Throughout all the exposures, it was fun seeing the many streaks now and then (mixture of satellites and meteorites).

I am happy with these results for this equipment, but do see room for improvements.

Only filter was UVIR. Sensor was ZWO ASI1600MC-C with dew heater.

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.
