SkyTee-2 mount

[laudropb]

I just bought a SkyTee-2 mount to use with a Skywatchers 120 Ed. I set it up yesterday, but was amazed that no instructions come with the mount. It was a bit like doing a jigsaw using a photo of the mount. However all went well apart from the fact that when the scope was pointed up above about 20 degrees it started to slip . I tried balancing it by moving the scope up and down the mounting plate, but to no avail. Is there any way to tighten the altitude bearings to help prevent this ?

Was it slipping even with the clutch locked?  That would be unusual, my 13kg skyliner tube is held steady with the clutch locks, even when heavily unbalanced.

Is this a new mount, or second hand! If new make sure you tighten the lever to lock the clutch as tight as you can. If it still fails after this and it is new I would contact the seller. 

[laudropb]

It is new. I will give it another go then contact seller if not any better. I did tighten the locks but perhaps I was too gentle.

Do a search for "Johninderby Skytee" and you'll see what this mount is capable of with a little bit of tweaking. Here's one with a few pics. He's also had it on a goto equatorial mount iirc:

I may do the mod to use the other end of the Skytee rather than use the top mounting plate. Would balance the mount out better, and make the scopes easier to use.

which 'puck' are you using? if the top mounted then i had this issue also - the assembly wasn't tightened enough, had to turn the whole ring+puck so screwed in tighter - took me ages to work out. Best way to check i found was unscrew the end cap part (loosen the black grub screws) then check that sits tight. Also check the wing nut that locks the top assembly to the clutch is tight enough. Hope that makes sense

[laudropb]

It was the top mounted saddle. I will give that a try. Thanks for the help.

from what I recall you can tighten it without removing end cap, make sure its tight but no need to overtighten. I found you can mount it one side and will stay tight as its same way as thread tightens if that makes sense? care not to strip the grubs, then only need to be finger tight at most. good luck and shout if need help

[laudropb]

Thanks again. Outwith my Dob tonight as the sky is clear for a change. Will set up the Skytee tomorrow and have a play.

[laudropb]

Thanks for al your advice lads. I have managed to solve the problem with your help.

[Knighty2112]

Glad you got it sorted. Hope you have some great views with the new mount.  

[laudropb]

Thanks. Not much chance in the near future. We are in the grip of storm Barbara and it is really wild outside.

Glad it's resolved!
