Hotech Self-Centering 1.25"/2" Laser Collimator

Hi All,

Selling my Hotech SCA Collimator I bought from Telescopes & Astronomy less than two years ago. It worked very well in my 12" dob but my SDM came with a laser collimator and this one is not getting used any more.

It has got a self-centering 1.25" nosepiece with a rubber band that expands when you tighten in and the collimator is always centred in the focuser. Also comes with 2" self-centering adapter, I used it in 2" mode as most of my eyepieces are 2". I found the self-centering mechanism very helpful and collimation results reliable.

Here is a link to the pdf manual for the collimator explaining how it works:

I paid $235 for it then but our dollar is where it is now so it can be yours for
$135 + postage [NOW SOLD]
As far as I know it is difficult to buy these from overseas due to customs restrictions on lasers.

Comes in a nice padded box. Pickup from Mentone (3194) is welcome.

Contact me via PM.
