Hi, group,

 

I consider to update my Newtonian telescope by an ASA OK3 or OK3-Z focuser. I am aware that this will require drilling new holes in my OTA. But what I must anyway know in advance is the total height of the focuser. If it is too high, then adapting the telescope would be much more complicated than just drilling a few holes. Unfortunately, I was not able to find the required dimensions on ASAs site or anywhere else in the internet.

 

So can anybody who has an OK3 or OK3-Z tell me the height from the OTA to the upper edge of the drawtube, without ASA's extension tube? Ideally the values for minimum and maximum focus position?

 

 

Best regards,

 

Bernd

Hi Bernd, Here you have a link to a diagram with the dimensions of the ASA OK3-Z. At least they were so when I bought it a couple of years ago...
