I know I'm being padantic, but I have another question about Crayford focussers...

[Mr. Subatomic]

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!:bowdown:

You would have to ask the dealer themself to clarify. I suspect that if the 10:1 is standard it would be specified.

I have however heard that Bintel have been persuaded to upgrade to 10:1 for a small fee. Highly recommended!

[Mr. Subatomic]

Yeah that's what I was thining, they might be able to upgrade me for a small fee because there's only a $20 difference between the two focussers.

Thanks!
