M101 - Pinwheel Galaxy

Pulled out some data I had largely forsaken as there were a number of challenges with it. I had my dithering set way too large for imaging unguided which can result in frames not lining up well at all when you go to register all of the data.

Thus, there is a fairly decent crop here of the native field on the ML16200 chip.

To add to this, my flats did not correct properly, and I have since sold both the camera and the telescope used for this, so I had to get pretty inventive to get the data reasonably cleaned up.

All in all I am surprised at how well it came out. While much better than a previous project I had on this target, this is one I plan to revisit with the 12.5" AG scope later.

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.
