Brandnew TMB 100/800 LW Modell Datas
- We took the time and did a final improvement for next time, about which i talked before.
New run of alu lightweight tubes with follow optimized design :
The middle main tube is from Vixen and the tuberings and finderbracket is from Vixen , new made retractable dewcap, for quickfocuse we designed now a sliding drawtube moving into the tube with an stopping handscrew and attached 2" Feather Touch focuser . This new combination allow to use any binoviewer with any diagonal mirror without optical path correctors and still get focuse . Also includet the mountrail for Vixen Mounts.
See the specs,
1, tubeweight was keeped
2, transporting lenght is a bit shorter now
3, maximum reachable backfocuse is now 246 mm, this is really more than enough for any body , for any binoviewer with 22 diagonal and even for most crazy eyepieces to reach focuse without barlowlens.
4, the shortest backfocuse is now 146 mm, this shall be enough if you use a 2" stardiagonal ( usual 120 mm way) plus focuse was of focuser to reach focuse.
If you want to use a 1.25" stardiagonal, you need a extension
I hope this final design find now a satisfaction by any new buyer
