Hi everyone,
The Bintel and Andrew's Communications websites advertise their GSO 8" Dobsonians as having 'Crayford focussers'.
However, the Guan Sheng Optical website advertise them as having 'Micro 10:1 Crayford focussers'.
I was wondering whether Bintel OR Andrew's Communications mean 'Micro 10:1 Crayford focusser' when they describe the GSO 8" Dobsonian as having a 'Crayford focusser'?
Thanks a lot for all of your help!
