I have been an Astronomer since 1988.
I have done a lot of astrophotography during
this time. I have also done a lot of viewing.
I have looked through a lot of optical trains for
various OTA's (Optical Tube Assemblys). My
Main Scope is a C11" schmidt. I also have an
a SV80mmS Refractor put out by Stellavue.
I was really impressed by these Binoculars. I sued
them on a week and 1/2 adventure I spent at Yellowstone National park. I have also used them
to find celestial objects in the universe. The wide field made it easy to find celestial objects.
GREAT BINOCULARS !!!
