I would agree with that advice in most cases. Probably > 95% at least. If we were talking about sticking the focuser on a premium telescope, I don't know that the GSO is appropriate in that situation. For instance, if you shelled out $15K plus for a 25" dob from Peter Read at SDM telescopes, which are as good as they get, you would feel somewhat short changed if the scope arrived with a dual speed GSO crayford focuser on it. Somehow a $100 focuser on a $15K scope doesn't quite fit.

I have a dual speed GSO crayford on my 10"/F5 dob and a dual speed Feathertouch on my 18" Obsession. The GSO focuser does a very nice job for $100. It isn't remotely in the class of the Feathertouch, which are the best available for visual use IMO.

On the basis that Norm is a Commodore man, I think he would be very happy with the GSO. Conversely, if he was building a scope from premium components (Suchting mirror etc) he may want to consider a premium focuser. The Moonlite dual speed is also very good, but a full grade behind the dual speed Feathertouch IMO. Considering the Feathertouch is $500+ it should be very good.

Cheers,
