Owl Cluster - NGC 457

Here is a quick first light with my Explore Scientific N208CF imaging newt with my Atik 460. (Cooled to -20) This is RGB only - 10 subs of each color, 2 min each, binned 2x2. 1 hour total integration.That gives me an image scale of around 2.34"/pixel - what I learned here is that I'd need to do some Lum at 1x1 to really look good. When I zoom in on these stars, I find that they look a little blocky. Looks like I got the spacing with the Explore Scientific coma corrector correct, stars at the edge look OK. My guiding was AWFUL last night, so I'm amazed the stars aren't egg shaped. Combined in Pixinsight, bias frames only, needed to apply Morphological transformation to reduce the number of background stars. For a quickie experiment - I'm happy with it, but still lots to learn and fix here.

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.
