Hi, I am thinking about these for birdwatching. I have never used one or looked through one. Can someone with experience in choosing and using one kindly give me some hints?
-which brands are good
-any optical drawbacks?
-other thoughts?
-if I use this in a finder for astronomy, any issues?
Thanks very much,
Ivan
I have used the Baader 2" extensively. For magnifications used in birding it will work just fine and you will be able to track a subject as it moves. If you are planning on doing high magnification imaging then a high quality star diagonal might work better although I have never attempted daytime imaging with the Baader amici or a standard high quality star diagonal. For night-time use, I have found the amici prism to work just fine at low magnifications and has been mentioned, for low power star-hopping with a Dobsonian it is wonderful.
