When I try to find an object it’s way out of view. My best guess is about 1°. The telescope is 200/1000 and I have a 40mm 40° ocular, which should give me a FOV of about 1°35′. Some objects I can’t even see it with the finder scope, which has a slightly larger FOV. But it seems to depend on the object, for example last night it was possible to find Mars with the finder scope. It was right at the edge.
I did repeat alignment multiple times but always got about the same bad results.
Possible problems that I can think of:
I messed up data entry before 3 star alignment. I use GPS from my phone. I’m in Switzerland and set the zone to “Zone 1”, which is GMT+1, right? Time was certainly correct. Daylight saving was activated. I just checked again and everything seems fine.I messed up alignment somehow. The index marks are there and I moved both. I did align the German mount to Polaris before I started with the goto alignment. When I did the actual alignment I could actually find 3 stars to align. It already seemed imprecise there, but with an app on the smartphone I could find them. So this should be fine. Os it normal that it was already rather imprecise there?The data on the mount is outdated. This thing looks like it’s from the last millennia and it probably is. The NexStar hand control has a RJ9 connection. I can’t see the exact version on it. But it has a large sticker warning me to never target Polaris (but it’s on the list of named stars). “INFO” doesn’t show me any info about the device. Should I buy a new hand control? I think NexStar+ is compatible with the mount and comes with USB.The motors are bad. How likely is that and how could I test this? I would like to start at Polaris, then find something that is way south, and then go back to Polaris. But the label tells me to never do this. And I’m not the guy who would cross the streams of unlicensed nuclear accelerators, so I won’t do this either. What would be the closest object to Polaris that is still save? Yildun? Epsilon? Zeta? Kochab? Pharkad?My expectations are way too high and this is just normal. That would mean this was a complete waste of money. Sure, it can track objects or rather rotate against the rotation of the earth and that seems to work well enough but then a motorised mount for just that would have been enough.
The mount is a “Celestron AS-GT mount”. I think it’s a C8-SGT. That’s on the manual but this manual is also for C5-s and C9.25-s. I use a different telescope than the one it was originally sold with. It’s a bit larger. But as I understand the Goto uses the data from the alignment and then does some calculations to make sure this doesn’t matter.
The powerbank I use is from Celestron, so there should be no problem with that.
I bought it second hand I couldn’t update the firmware. I just used it as it was.
