Hi Guys,
I have recently purchased a Celestron 150mm (6 inch) Achromat F8 refractor and am now looking to pimp my ride.
My first step is to purchase a reasonably priced dual speed focuser cos my existing "Rail" style focuser leaves a lot to be desired.
Therefore I need your help in resolving the following questions

:
1) How do I determine what size/ type of focuser I need?
2) What is a reasonably priced focuser?
I need to get this upgrade past the Home Ministry so "recommendations for the common man" would be greatly appreciated.
What are your thoughts
