Skywatcher 180 Mak Pro tube weight

[Rob]

Whats the weight of this tube minus the 9x50 finder?. I'm trying to work out CG5 weight limits for OTA's.

Thanks

Rob, according to SW's website, the OTA is 7.8Kg so it should sit on a CG5 with no problems. FWIW, I use my Argonaut on a CG5 which is considerably heavier (10Kg+) and it's nice and solid.

But the mproblem with a Mak is that the weight is concentrated at the ends, making the moment of inertia greater than its raw weight would suggest.

Reviews of this scope have suggested that an EQ6 is the minimum mount which will do it justice.

I have a 180 Pro and use it on a lightweight Vixen GP-E mount. It is a perfect combo.

PS Rob I have been trying to sell my Mak for a while but withdrew it after 3 buyers gave backword. I figured after Christmas would be better.

The weight on my argonaut is at both ends too (being a Mak-Newt), plus it's considerably longer than most MCT's so the intertia you mentioned would be more as well.

EQ6 sounds like total overkill for a short 7.8kg scope, regardless of where the weight is. Having had an Intes Micro Mak of the same weight on CG5 and LXD75 mounts with absolutely no problems for visual use, can't see the 180 being any different.
