EQ6-R Pro + Sky-Watcher 200PDS + SVBONY Finder Scope SV106

Good afternoon. If it's not a secret, which seller did you buy from, and how did the telescope arrive?

Good afternoon! Vernaid Telescope Store. I left a review with a photo. The box was dented. It wasn't packed very safely—there was no additional protection on the sides. Something hit the side, luckily right on the mounting plate. It was even slightly bent. Everything else is fine.

Understood, thank you very much.

Hello. Regarding your Sky-Watcher 200PDS telescope, when you change the position of the tube in space, does the collimation stay aligned or does it get misaligned? I mean, suppose you performed collimation, started imaging a deep-sky object—which takes a long time—and the tube rotates somewhat. Or, for example, you imaged one object, then another object: between these changes in the tube’s position in space, does the collimation of the tube stay aligned? Thank you in advance.

Hello. I haven't had much chance to shoot DeepSky with it yet. It seems to hold collimation even after careful moves from the house to the backyard, though sometimes the collimation unexpectedly went off. Overall, I haven't gathered enough usage statistics so far.

No, not quite what I meant. I was referring not to when you carry the telescope from storage and mount it or back, but specifically when it's already on the mount—you've set it up, collimated it, started imaging, and I wanted to know whether the collimation gets thrown off during that process or not.

I'm just assuming that even when carrying, mounting, and polar aligning (the ASIair rotates it 60 degrees during this process, and I repeat the alignment in 2–3 steps), the collimation shouldn't drift during long exposures. It doesn't seem to shift, but as I mentioned, I haven't done many imaging sessions yet, so I can't say for sure. It also depends on how tightly someone tightens the mirror clips. If you're worried about astigmatism and only tighten them lightly, the mirror can shift—that happened to me, and I later tightened the screws a bit more.
