The Serrurier is just over 11 kg all up, no accessories. Total loaded on the mount is 17 kg. It is also better centre balanced than most scopes which minimises the counterweights required to keep it stable.
EQ6 is rated as 25 kg but recommended to be better at half that for photography. I'm inside a tinshed Ob so windage is not a major problem but the open structure of the OTA reduces wind effects as well.

What options does an 10" give you over an 8" ?
Long exposure and stability is the key for imaging, not so much aperture.
You can buy 8" or 10" Newts specially designed for imaging but be aware that larger apertures also introduce more coma effects from feild curvature.

I think my ideal imaging scope would be a longer focal length (f8) 6" newt. Big enough aperture to keep exposures short, long F to get decent mag and minimal curvature to correct. No refractor chroma either.
If I spot a mirror or cheap scope to convert\rebuild that will be my next build project. Would be nice and light and easy on the mount.

All that being said I'm about to remount the 10" (I'm using the LUNT at present ) and try out the ZWO camera on it.
