Baader Clicklock Extension tube...extension

[Littleguy80]

I use one of the Baader 47mm Clicklock extension tubes (https://www.firstlightoptics.com/adapters/baader-2-inch-click-lock-cl-extension-47mm.html) with my 10” dob. Works great. A recent eyepiece purchase hits focus right at the limit of my Focuser with the extension tube. I’m trying to find a way to extend the optical path by 5mm or so. The extension tube is essentially an SCT Clicklock with an S52 2” nosepiece screwed in. 

I’ve not had much luck finding a way to extend the optical using this thread. Thought I’d see if anyone out there has a clever way to do this? I’d prefer not to have the eyepiece or extension only partially inserted as a workaround.

You could put a parfocal ring on the barrel of the clicklock extension.

They add 5mm each and there will be enough barrel remaining for it to still be securely gripped.

Great idea. That should work perfectly.  Thank you very much

I got the parfocal rings this week. This Evening I tested all my eyepieces and they all reach focus with a little wiggle room each side. The extension tube still feels good and secure. Thanks very much for the suggestion. Works a treat
