I'm sure can't be the only person to have noticed that even with the RA clutch lever fully locked the slightest nudge will move the telescope on that axis and exactly the same for the DEC axis for that matter too.

This strikes me as potential real problem - has anyone done anything to mitigate it?

I haven't had a chance to set mine up properly yet Chris but that sounds exactly like my titan

Oops-perhaps I spoke too soon. I seem to remember a video from an Austrian astro supplier who tried to move the mount but it was fairly resistant. Will have to look at the video again.

PS Had another look at the video - looks like accurate balance is going to be essential.

This was the video - http://www.youtube.com/watch?v=KMJIb5PSSFY

I finally managed to get the EQ8 with the CCD/FW combo going on my BabyQ that I liked. So it is now ready for some serious imaging. So last night I had it in place but with a piggyback guidescope and using a Lodestar as a guidecam.
I found (again) that I have to recalibrate my guiding every time I start Maxim - which surprised me since in the past and on my other mounts, Maxim would remember the calibration settings from the previous session. Not a big pain, but a pain all the same.

Once guiding settled down - and it takes longer on this mount that any other I've had - it does not have any spikes - in fact it's pretty darned smooth - but I'm only guiding at about 300 mm FL so you wouldn't expect too many wild swings but all in all, I think it guides pretty well.

All the auguries are pretty good from my perspective.
Peter

I took this video a while back - its not a sophisticated test, but shows how solid my clutches are! I suggest that some simple adjustments are needed for others: http://youtu.be/ArbNmPd_lvI

that calm voice - such acting abilities - legendary !!

I was extremely impressed with that test, bomb factory and a hammer for you

didn't that dampen out quickly - as far as I am concerned that is better than the titan in the doghouse

EQ8 arrives in New Zealand

Just wanted to say thanks to all you guys that posted about your mounts, following these posts made it so much easier to get setup when ours arrived, just need to get onto a permanent pier. The 12 inch Newtonian sets on the mount fine, very stable.

that's an awesome view - to think a few years ago this was a pipe dream

Ah yes, a whole new career becons! I really did give it a damn good shake - I was online doing a google hangout demonstrating it and had to record the video.

Looks like a clear weekend coming up - I might finally get some quality time with the scope to finish the set-up. Not that there has been much to do really.

I do get the prize of being the first person in the world to break a bit though. I'll take a photo and post it up whilst everyone gets to speculate which bit. No-one will guess in a bazillion years

the plastic holder - or the clutch latch, maybe the geared knob

I put the question to Rob McIntyre at Tasco and thought this forum might be interested in his response:

"The clutch levers may be at the end of there travel. You can adjust the position of the lever, buy undoing the retaining screw on the lever shaft.
As they have the same star position setup as the NEQ6.
"

I will give it a try later today if I can.
