Regarding the planets, note that I don't post them—there's excessive chromatic aberration from the positive and negative lenses from AliExpress. My cell has 9 adjustment bolts: 3 for the lower, 3 for the upper, and 3 for setting the air gap, collimated using Airy disks.
The photo is just too small, can't really make out anything. I see the step motors on the focuser and on the DEC? =) On EQ1-EQ2, DEC is adjusted within a very small range, right? :( They don't have full circular rotation built-in. :(
There's also a hammer as a counterweight, I guess? xD Should have used a white tube, it's stiffer. But overall, it's a hellish construction, of course... in a good way )

And it actually works! =)) Even though the chromatic aberration is insane, it works :))
Props for the very skillful hands! :))
