Hello. I am looking for an upgraded 1.25" focuser which would have the same hole pattern as a stock Orion Rack and Pinion 1.25" focuser that comes on a 6" Classic Dobsonian Telescope. I really don't want to have to drill new holes in the reflector tube. Looking for something that has tighter tolerances to say the least. The stock focuser tube has lots of movement while using the focusing knobs. Enough to knock the image being looked at  out of view until the knob is turned back in the direction of the telescope tube. This is due to only 1 contact point on the focuser tube that holds it in. Any info would be appreciated. Thank you

This probably the closest thing.

Not sure if it's a direct bolt on but it should fit the tube.

It says the curve of the focuser is for 7"-9" diameter tubes. I have a 6". Thank you very much though

The mirror is 6 inches but the tube is around 7 inches...
