Howie Glatter Laser Collimator End Piece/ tuBlug

[Sentinel]

I am now in need of a replacement for my Howie Glatter Laser Collimator end piece (1mm aperture stop), as it is very loose and will come out, one of these days. I do not wish to lose it or have it bounce onto my primary mirror. I have posted the one I have as image attachments.

I believe there is now a replacement. Has anyone seen one, or can post an image of one for me?

Also, is anyone using a tuBlug?

Thanks

Reckon this is a good application for Loctite, I think that is how it is spelt. Add that stuff and nothing moves.

Ne definitely not...the black end piece has to come out every time to switch to the barlowed laser attachment.

Also there is no thread.
