Celestron C90 old vs new model comparison
« on: 21:14:36, 09 March, 2016 »
Hi,

I have put together a comparison video of the old Celestron C90 from the 70s-90s with the new model.

It is here on YouTube:

If anyone has experience of collimating the old unit I would be grateful to hear your tips!

Thanks,
Graham
