Ok, I have just filled my cart at Teleskop Express with 500+ euros of goodies, but now am having second thoughts.
My problem is getting the absolute best diagonal (for the best price of course). I currently have a 2" Bintel 99% mirror diagonal and an old University Optics 2" prism. The difference in viewing at high magnification (120x +) is substantial. The UO prism is way ahead in every respect - no scatter, better resolution.....only problem is keeping the UO prism square in the visual back. The UO prism has the worst mechanics possible, the 2" nose piece is sloppy in the holder and will not hold square and the eyepiece holder is not much better.
Now I had thought to order a Baader T2 Ziess prism with clicklock and 2" nose piece (270 euro), but now am thinking perhaps spend a bit more and get the Baader 2" Sitall mirror (357euro) or max out on the Baader 2" Zeiss prism (378 euro).
I only want to do this once - I realise if I go for the T2 option I will have to keep my Bintel 2" mirror for wide field.
Any thoughts on the 2" Sitall Mirror Vs. the 2" Zeiss prism - as said earlier, my thoughts are that prisms are way better than mirrors.
