o-ring for SkyWatcher 50x8 finder scope

[pjmaciw]

Hi,

I have just brought a used Skywatcher 250 dob but the 50x8 Finder scope is without the o-ring so it flops about and is useless.  Does anyone know what diameter the o-ring cross section is or where I can buy one from.

I have ordered a Rigel QuickFinder but it would be nice to have the finder scope working as well.

Thanks, Pete.

Hi Pete,

Alternatively you could use a thin elastic band - its what i do.

If bought new the supplier would sort you - they sometimes hide in the box somewhere. An elastic band works well or take a trip to your nearest hardware shop i bet they would have one

Astroboot have come up with the goods.  One o-ring on it's way.

Just need some clear skies now!  

Thanks for your replies and suggestions.
