M101 Pinwheel Galaxy

This years version of M101 The Pinwheel Galaxy. This is really a test for me using the new QHY410C camera with my Edge 11. The full frame sensor definitely shows I need to work a little on either collimation or squaring the sensor to the focal plane. Either way I am very impressed with the camera. I need to try this on my long refractors if we ever get some more good weather. I am looking forward to experimenting more with this camera and different scope combinations. This image was using the camera's Low Gain mode to take advantage of the large full well capacity. Gain 10 Offset 13. I think I may prefer the much lower noise High Gain Mode when I get to test that.

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.
