Hi Jean-Yves,
If you have the short, large diameter shaft, then yes, you can add
the shaft extension. See:
http://www.astro-physics.com/products/accessories\;
/mounting_acc/cwshaftoptions.htm
You can also use one of the longer shafts. I use the 14"x1-7/8"
shaft on my Mach1 and it works well.

Kurt Mihalco

Hi,

I have a question about counterweights:
I tested last night my LX200R10" + AO7 + ST8XME on the Mach1.

I was short in counterweights: I use the shorter optional shaft and

the

reduced offset distance does not give enought moment of inertia to
balance the OTA +++

I realised this morning that I could screw the normal shaft to the

end

of the optional shaft and that addaitional offset weight would give

me

a good balance.

Has anyone already done it? Any counter indications? Or does Astro-
Physics sell a shaft extension for taht short optional shaft?

Thanks

Jean-Yves
