Hello all.
I have a XX12" Orion Truss Dobson with Inteliscope. Since I'm starting to know my way around in the sky (and bought
Skyscout just in case) I've been considering upgrading. On a lighter Scope (the scope's huge wooden base kills me
when carrying it and placing it into my pickup). I't doesn't necessarily need to be bigger. It can be another 12" or
up to 16". Now, we all know the the ultra light/ultra compact Obssessions are wonderful... but I don't have the
money to go there.
These are some ideas limitations that I have:
1 - I live in Portugal so it must be a scope that's sold in Europe.
2 - I use DenkmeyerII and a heavy 31mm Nagler (1kg-2pounds) So structure strength ans stability matters.
3 - I can't spend over €3000
4 - I've seen this Italian Brand Dobson, RPAstro (anyone knows about it?): http://www.tecnosky.it/rp_dobson.htm
5 - I was remotely considering the GSO/Meade 16". But once again wheight will be a problem.
6 - Is there any other Brand, selling in Europe, that has an ultra compact/ultra light Dob up to 16" and €3000?
7 - I know these 2 other European brands but they're a bit too much for my pockets:
- http://www.dobsonians.co.uk/index.html
- http://laclefdesetoiles.com/browse.php?cat=32&brand=34
8 - I'm a bit concerned about the primary mirror quality on the italian brand one (16" F4,5 in BK7 glass with a
correction superior to 1/5 lamda (PTV), 91% reflectiveness with protective treatment (SiO2). 41mm thickness)
Anyone with ideas and good solutions?
Thanks.
