First Light: The Leo Trio

Leo Triplet (M65, M66 NGC 3628). Thanks to a bad run of weather, smoke, travel, and equipment mishaps, this is the first image I've posted in many months. It also represents a big change--I've put my C6 Hyperstar rig to the side and I've begun working with a more traditional (and somewhat more reliable) refractor set-up.

This image captures first light from my new Askar FRA500, which arrived in March 2023. I was so eager to put it to use when it arrived--and yet reluctant to detach the ASI183MC Pro that was integral to my Hyperstar rig--that I decided to shoot with a rarely-used un-cooled planetary camera (ASI585MC) that was lying around. The night was a success--the new scope worked great--but the resulting image, which reflects about 3 hours of integration, was extremely noisy, and it didn't seem worthy of further investment. Months later, bad viewing conditions continued and I was in need of an astrophotography project, so I completed a set of calibration frames to cancel out some of the noise, and processed this final image. It's not a masterpiece, but I'm glad to make good use of my test data and share this image with you.

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.
