Quite a bit of experimentation from the backyard. First light testing with the iOptron CEM40 mount. Tracked beautifully.

First try with full frame Canon RA on the AP Stowaway. About 90% of field is usable. Extra vingetting introduced by the in camera full frame STC filter. Just a little on the edges. I would likely crop what was severely vignetted by the filter anyway.

All in all, I think a usable combination, but need a lot more data on this target to really smooth out the shadows. I am getting used to f2 imaging and the incredible signal to noise that it offers. So, when I go back to f6 imaging, it is a new ballgame.

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.
