M51 Cropped ~ A 2nd Test with the Meade SN10

Once again, a threat of clouds kept me in my Bortle-6 driveway last night. Clear skies afforded me about two hours to set up and continue in testing my recently acquired new/old Meade SN10 Schmidt-Newtonian. My first test rendered spiky stars, so I loosened the mirror clamps - they barely touch now. Transparency was fair and no wind; the mount was level, the scope 3D balanced on both axes, dead-on collimation, and a polar alignment 47" from the NCP. Still, though, wonky stars. The only other factor I can think of is tilt (as a result of slightly undersized M48 extension pieces that slide into the TS-Optics Monorail 2" focuser). I can think of a fix for that. Qualified commentary is welcome. Otherwise, the scope (so far) is showing itself capable of decency. Even so, I am hoping for better ....

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.
