FOCUSER

A This was an easy choice ...

The focuser was the easy choice of the telescope, i used a starlight instrument feathertouch focuser for whil on my C8 , and it is really a big piece of work. I could really go for no other focuser.

The gold 1:10 reduction allows to focus with the hand even with fast newtonians, and starlight now offers a motorized version.

I have owned several focuser ( 5 ! can't give names here to respect commercial french laws , but i should ... ) on the C8 , and really buying a starlight instrument was the best thing i bought , after the telescope itself.

Ok , it is not the most important in the dark , but truly , it is beautiful !

Just a word to say you can see 1:10 planetary reduction on several focuser now, but if the 1:1 focusing mecanism is not perfect, it as you where putting new tires on car without a motor !

Really this focuser is the BEST VALUE FOR THE MONEY, every $ is at the right place when you buy one.
Look at other focuser, what other focuser roll's on stainless steel ?

You can't have a better focuser at this price ! And you can't have a better at a lower price.

The way the starlight moves needs a very accurate work ... i'm quite sure it won't be cloned !

B Focusing methods

The gold button has such a fine control , that you can use the tooth on it as if you where using a digital micrometer ( and save a lot of money !) , just put a needle point to one tooth of gold button, and turn to the next tooth , you can be *sure* the focuser has moved from the right value.

Here you can see a curve from with method, beetween each points i have 5 gold focuser teeth. At the end i go back from the total number of teeth , i make the curve, and come to the best position.

This is a very strong method to make focus , and TO BE SURE YOU ARE AT THE BEST FOCUS AVAILABLE
