CatsEye Collimation Tools for f3.5 to f6 newtonian

[CarlDori]

Hello

I have for sale a set of 2 inch ( 50mm) Catseye Collimation tools I used for Day Time collimation.

Set can be used to collimate f3.5 to f6.0 'scopes.

Comprising centre spotting template and centre triangle spot with spotting instructions, the tools are an adjustable (f3.5 to f6.0 )  Telecat XL, this is a sight tube allowing for precise secondary mirror positioning and rotation. The BlackCat allows for precise primary mirror adjustment. The autocollimator is used to fine tune the tilt & rotation of the secondary with respect to the primary and focus tube after going through the Telecat and Black cat collimation routine.

Using the Telecat XL and Blackcat are intuitive easy to use and mastered quickly, the autocollimator however is an absolute pain to get spot on but worth it for precise. 

There are online tutorials available that explain this better than I can.

The tools, wooden box and cardboard tube with spotting template, template instructions and a spare triange altogether for € 150.

Inspection  welcome. Pickup from Vranic, 45 km from Belgrade, I can't deliver as I don't drive..

Reason for the sale is, I'm into my seventies and I'm downsizing to what I actually use.

Best Regards
