Optically it is a fine little telescope but like many users I found that trying to get perfect focus using the barrel fousing ring could be a bit frustrating due to the relatively coarse adjustment and the almost unavoidable vibration caused by having to grasp the tube to focus.
I searched the web looking for an in-line helical focuser that could be added at the eyepiece or at the visual back but discovered that the costs for the focuser and the required adapters would approach or exceed what I paid for the telescope itself.
Deciding to try to come up with a simple DIY solution I set off to Home Depot to see what I could find.
What I came up with is decribed below and is the cheapest and simplest solution since it utilizes the supplied 0.965 diagonal. As an added bonus it allows the use of 1.25" eyepieces which are prefered over the supplied 0.965" eyepieces.
The adapter is made from:
Carlon 1" PVC Terminal Adapter - one Male & one Female @ 50 cents ea.
A piece of 1 inch PVC conduit approx 3/4 " long
I didn't want to purchase an 8 ft length of conduit (Minimum size sold) so I just bought a 45 degree elbow piece for a buck and cut the 3/4" straight piece from it.
The diagonal that came with my scope has a split tube on the eyepiece side and uses friction (not a setscrew) to hold the eyepiece in place. I dont know if this was standard over the production life of the scope but if you have a diagonal with a setscrew on the eyepiece end then you will have to make some modifications to attach the lower part of the coupling to the diagonal.
The finished product is shown in the attached photo.
Construction details are outlined in the next post.
