Bresser Messier AR152s eyepiece tube diameter?

[rodrigol]

Hi,

I've got a AR152s and started thinking of improving the focuser by adding a SCT crayford. In principle this should be possible by installing an adaptor between the focuser's back plate and the SCT focuser thread (please see the following image link: http://stargazerslounge.com/uploads/monthly_08_2014/post-8274-0-92921500-1408988106.jpg).Issue is that I can't find the dimentions of the AR152s focuser back screw? I think this is Anyone have an idea?

Thanks!

Put a MoonLite on it.

Very tempted...costs almost as much as the scope. Yours is an Explore Scientific AR 152? I wonder because my back plate is at the end of the focuser tube. Is yours also?

Thanks for replying!
