i recently acquired a Baader MaxBright.
I will use it for planetary and deep sky observations with my Mak150, C8 and 12” Dobson.
whereas for the deep sky I don’t care about seeing a reflected image, for the moon it is mandatory for me to see it right. And I will not neglect a terrestrial use, neither.
So I need a (good but not too expensive!) erecting diagonal.
the MaxBright comes with all the Baader adapter arsenal so it would be nice to have an Amici or other erecting prism with thread rings. But it is not strictly required.
what I need is an erecting 90 diagonal (or even better 45 deg) with enough quality for astronomic use, for at least moon observation. For deep sky and planetary I will use direct or dielectric mirrors.
Now, what is a good Amici for terrestrial and moon observing?
I selected some:
This one is cheap and very conveniently angled:
This one is more expensive and I wonder what is the added value with respect the 45 deg:
then the APM erecting prism:
i know someone is also suggesting WO.
what would be in your opinion the best choice? Feel free to add options.
thanks a lot
