Not a jibe, just a genuine observation I am seeing in a LOT of Redcat images.

Hi L,
It's potentially a lot sharper (some 3x sharper/higher res) than what can be seen in the web image Peter linked to, since
1.
the original photographed image scale was something around 4.4 arcseconds/pixel (based on the 250mm focal length of the Redcat optic on Full-Frame, roughly 8.24 degrees wide over the 6720 pixels of the Canon EOS Ra sensor),
versus
2.
the displayed web image scale of around 12.8 arcseconds/pixel (based on an image estimated at around 6.85 degrees wide [vide Stelllarium comparison] over the 1920 pixels width of the web image posted)
Best
