Feather-Touch MicroFocuser Fitting Instructions (pdf)
Which MicroFocuser fits my telescope?
If your telescope is less than a few years old, check the style of the back cell to see which version of the Feather-Touch SCT Micro Focuser you need. If your telescope has a flat back (left picture), you need the standard 'C' MicroFocuser. If your telescope has a triangular pattern on the back (right picture), you will need the 'CPC' MicroFocuser.
For the Celestron 6SE, you will need to measure the outside diameter of the flange of the stock focuser (the part of the stock focuser that mates to the rear cell, as Celestron uses 2 different size of flanges, 1 that is 1.5"/38mm and 1 that is 1.6"/40.6mm. By default, we stock / ship the 40.6mm flange version but if you require the smaller option please order the 38mm version.

I am very satisfied with this purchase. Carefully remove the original focuser and following the instructions I mounted this Microfocuser which is really high precision. I consider it an essential equipment for perfect focusing.

The focussing unit that comes with the standard SCT really isn't up to the job. Trying to get tiny movements from its high gear mechanism to get the perfect focus is very difficult. Using the low gear focuser on this unit is effortless, and it is easy to get a fine pinpoint focus every time. In particular I have noticed that it aids getting sharper focus at higher magnifications. The unit still has a high gear control to quickly move the focussing, so nothing is lost by replacing the old one.
The instructions for removing the old one, and fitting this are very detailed. Once I had gathered the correct tools together, and understood what needed to be done at each step it took me about 10 minutes, with no problems.
It seems like a lot of money to me. However, it is a good make, and I guess it uses the best materials, and is machined to the highest quality. So far it has worked perfectly. I did hesitate with the price, but I would hate to go back to not having one. In fact if I bought a new telescope I would factor in the extra cost of buying one of these from the start.

Q1. Will the SCT Microfocuser affect my back focus in any way?
No, the microfocuser replaces the existing focuser mechanism and gives you a finer focusing option. It does not affect the back focus.
