Hi
I recently purchased a SW600 and have found it to be a good performer for the money and went for the crayford focuser from My Astro Shop which is a straight fit with the SW6OO no holes to be drilled
The tube assy weights just on 10 kilos with most of the weight from the tube rings and the metal plate at the rear of the tube is fairly heavy for what it achieves by just blocking the airfow but can be removed with just three screws. The mirror is not pyrex where the 10'' version is and would have to be aware of this in summer.
I am using this tube assy on a VIXEN GPDX mount and while I was concerned of the weight factor for the mount did not realize that the longer tube of the newtonian (orig tube vc200l cass) now fowls on the tripod when pointing at the zenith and will have to have and extension made up to fix this issue
Regards
DAVE
