c80ed focusser,need a new one

[stafford_stargazer]

Would anyone out there be able to send me a link to which focusser and adapter i need to change mine on the c80ed.

Not to expensive but something better than the gluey thing thats on it

Gaz

The problem with the C80ED is that it uses a screw on thread to attach the focuser and the only supplier of an adapter is agena astro in the US.

there is another alternative- you heard of 'moonlite' yet? :-)

[stafford_stargazer]

Before you go spending £190 on the GSO from Agena, thought i would let you know Scopes'n'skies sell the Antares 1:10 86mm fit for £116 delivered. It's the same focuser as the GSO from Agena (and TS) but for a lot less. I would sell you an adapter but i can get it off the scope now.

Moonlite Focusers - MoonLite Crayford Focuser for Refractors

you know it makes financial sense!

[step_hen]

yep, its the antares version that i have.

£369 for a focuser......crikey i would be feeling ill after spending that much and i wouldn't go home either.

never used that scope but I'd try and service the one you have first. I bet you could clean it, use some lithium grease and then adjust the various grub screws and improve it?

it's a thing of beauty for sure but there's a lot more you could spend that sort of dosh on. It's a life investment I suppose so you pays yer money etc.

[step_hen]

strips of Teflon tape works a treat if it has any 'wobble'. There are two grub screws on the top that can be adjusted as well. Definately try regreasing it.

[stafford_stargazer]

no wobble,got rid of all that glue on the r+p,so its lithium grease you shouse use to regrease it?

Still it will always look ugly

Arhhh moonlight:(

I've been through the trying to improve the C80ED focuser bit myself, and though it an be improved somewhat it's never going to compare to even a cheap crayford.

The Telescope Service MonoRail crayford focuser is another alternative. It will handle nearly twice the load of the Agena (GSO) focuser and is a really nice and smooth focuser and the price isn't too bad at about £166.00 delivered. The only downside is that it doesn't have as much drawtube travel as the GSO or MoonLite, but a simple 2" eyepiece extender would take care of that if needed.

I put one on my TMB 80mm achro and I'm very impressed with it, much smoother and more precise than a GSO or SkyWatcher crayford.

You'll still need the Agena adaptor though.
