RamaSpaceShip Posted February 26, 2014 Report Share Posted February 26, 2014 Hi all, I would like to share with you the mean I use to easily adjust the balance on the Dec axis. I have made a modification to the dovetail so that I just have to turn a knob to precisely adjust the balance. I needed to use a PTFE spray so that the dovetail slides without effort. The image of this system is attached here: This is not patented and I strongly invite ASA to improve this design and add this very useful feature. Regards.

prefetch Posted March 17, 2014 Report Share Posted March 17, 2014 it's difficult for me to understand exactly what is pictured. could you describe what it does and how? Link to comment Share on other sites More sharing options...
Waldemar Posted March 17, 2014 Report Share Posted March 17, 2014 Lukas, could you provide us with a link to your system? Thanks in advance, Waldemar Link to comment Share on other sites More sharing options...
lukepower Posted March 17, 2014 Report Share Posted March 17, 2014 Hi Waldemar, I am still waiting it to be shipped from Michael Knopf. As soon as it's mounted I'll post some pictures. Anyway, the basic idea is to be able to move the plate on the mount by turning a knob Link to comment Share on other sites More sharing options...
nakbrooks Posted March 17, 2014 Report Share Posted March 17, 2014 (edited) Out of interest I use this http://admaccessories.com/Miscellaneous_Max_Guider.htm to piggyback my secondary OTA (125mm Hutech/Borg) on my primary OTA (ASA 16" Cassegrain). It allows easy but secure adjustment on all axes both for balance and co-alignment with the primary. I would not suggest it for attaching a heavy primary OTA to the mount though. Even though it is very solidly built it would introduce unnecessary potential for flexure. Nigel Edited March 17, 2014 by nakbrooks Link to comment Share on other sites More sharing options...
RamaSpaceShip Posted March 17, 2014 Author Report Share Posted March 17, 2014 it's difficult for me to understand exactly what is pictured. could you describe what it does and how? May-be this diagram will be clearer Turning the green knob causes the threaded bar to push or pull the dovetail. Best regards. Bernard Link to comment Share on other sites More sharing options...
