Hey folks!
Last time we talked about the focal length and the aperture of scopes.
This time we want to bring this two units together and see what scopes we can possibly create.
Discover “fast” and “slow” scoped of different kinds from the cheap lens scope to visit the moon right to the cutting edge “astrographs” like the RASA11 from Celestron.

After this video you will then have the first set of tools to categorize and classify the thousands of scopes out there.

As always: Clear skies everyone and till next time here on catchingphotons!
Greetings
Chris
