Cleaning a Televue Genesis-disassembly?

[Garyh]

Hi again everyone :),
While I am waiting for bits etc for my new setup, I would like to give the genesis a good cleanup as is rather dusty inside and I say it has ever been fully cleaned out for a long time or never.
Anyone that knows how to pull these things down. Any advice before I give it a go. I know the front cell comes of with 3 allen screws but not sure of the focuser unit and back elements? I have pulled apart camera lenses before so this doesn`t worry me that much.
Looked on the net with not much luck..

On the archives of the TV webpage there's a section on this... basically "no user replaceable parts within" The front cell should NOT be removed from the tube, don't know about the back cell ( remember it has a secondary lens as well as the focusser).....
I've got serial # 10007, with a bit of dust etc but never thought to pull it apart.

I'd take it into Bintel and get some expert advice/help.

Oh I have already pulled off the front cell a year ago!! Can`t see the problem there. I think TV don`t like owners cleaning/collimating there own scopes? they always say send it back to them.To dangerous to send to the USA..
Bintel quoted about $300 to clean. So thought I do it myself...
