View Full Version here: : TMB mono question

08-10-2006, 09:45 PM
Lately I'm thinking of adding 1 or 2 TMB mono's for DSO work. Most of you know that I have terrible skies (nelm usually 4.8~4.9) for galaxy hunting so every gain in contrast and transmission and .... is very useful.

Anyway, APM in Germany still has the 9 and 7mm units in stock and since I've have been working my entire summer vacation I'm going to give myself a little treat :). So, would it be reasonable to spend 150 on a tiny little ep when I can get a very good ortho for much less?

I would be going with the Baader orthos. A lot less money for about 2% less performance.

I've got the 18mm already and like it very much, shows me more stars and faint stuff then the Hyperion 13mm.
