Wow, thanks OP, for such a detailed post. I wanted to ask about collimation. I see a lot of people saying the large and small screws work in push/pull pairs, but that doesn't seem to be correct. If I'm understanding things correctly, the way to properly collimate these maks is to first loosen all the small screws (just a bit). Then, use the 3 larger screws like we'd do with an SCT. Here's the part I'm not clear on: when I loosen one large screw, do I need to tighten the large screw across from it, or do they function independently? Finally, once collimation looks good, snug up the small screws.
The procedure above is what SkyWatcher gives in their official collimation document, so I'm confused as to why people say to do it differently. Those posts have said to tighten/loosen a large screw, and then the small screw next to it will be looser or tighter.
