My 200P just arrived and oh my God... I have been trying to wrap my head around the mount for 4 hours.
The manual didn't really help so I decided to go on youtube, but again, I didn't find any good and detailed videos so I decided to ask here if there is any video or perhaps blog post that might help me set up the mount.
Thank you very much!
*by the way, is the EQ5 supposed to have slow motion cables? I only got 2 knobs (not cables) and I'm not sure if there is something missing or not... sorry, this is the first time I've used a serious equatorial mount or telescope.
Thank you very much!
I have quite severe backlash, such that guiding assistant just gives up. It seems to be about 11 secs in total, the one time GA came back with anything, but it's about 3-4 secs if I measure it by hand. Here's some guiding. Actually, it's worse when I'm dithering.
So, I tried measuring the backlash with by counting and it's about 3-4 secs. If I used PHD2 guiding assistant, mostly it fails, or it comes back with a very big number, like 11,350 msecs.
I tried entering this:
But then I got a see-saw mechanism, even when I dropped 8,000 to 3,000 it was the same.
I've taken the motor off just now and looked at the grub/hex-screw mechanisms. One hex-screw was loose, so I tightened it to hand tight and let the grub-screw off an eighth of a turn. I'll look again this evening.
I ran a three hour sequence of exposures on NGC6888 (with dither) and this is what I got on EVERY image. Amazingly, they stacked nicely.
So last night I ran without dither and it was mostly OK. What I want is full dither, but to do that I need to deal with the backlash.
Here's a photo of the motor and gears, most of the backlash seems to come from the top gear (ie the 12-tooth gear and its neighbour). I guess the rest comes from the worm-gear:
Does anyone have any suggestions? There doesn't seem to be a belt-mod for the EQ5 as far as I can see. Maybe there are better Dec backlash compensation settings I could use.
Sorry if this has already been asked ( I think it would have been, there are posts similar but can't see the the answer I'm looking for)
I have a celestron C8-N scope that came with a Cg5 mount, it's at least 10 years old and although it had a lot of use to start with it's been gathering dust the last few years.
So I would like to fit a motorised goto mount to it and was considering a synscan pro3 for an Eq5 mount.
Can someone tell me are these 2 mounts the same and if so will the synscan be OK for my Cg5 mount.
If not are there any others I should look at?

Hi! I purchased a Raspberry pi 4 4gb not so long ago with the intention of running a NAS and some other stuff on it. I have since then considered the possibility of using it to control the alt/az position of a mount like the Skywatcher AZ GTi with a python script running on the raspberry pi. I haven't purchased the mount yet since I'd like to hear if it would be possible.
A little more information on my main objective:
Weather satellites and radio has recently caught my attention and I'm therefor considering to mount a directional antenna on the skywatcher AZ GTi mount which then tracks a chosen satellite across the sky. The raspberry pi would be running a program that would send the alt/az coordinates to the mount. I have thought about sending the alt/az coordinates through a TCP socket but I'm not sure how I would connect (and if it's possible) the mount to the raspberry pi or the opposite way.
Here's a video of the current software I'm working on:
I've seen people control mounts like the Celestron nexstar ones but it would be ideal to make the small and light weight AZ GTi perform the same job. If you have any experience with the AZ GTi mount and raspberry pi I would highly appreciate your advice:)
Thank you in advance!
