A Low Profile CNC machined 10:1 dual-speed focuser designed for Newtonian Reflector telescopes of 9" to 15" aperture, and accepts either 1.25" or 2" eyepieces. High quality made focuser.
Provides an exceptionally smooth focusing operation with the utmost precision, with the aid of its fine-focusing facility.
Purchased to replace an R&P focuser on a failed Meade Lightbridge 16 restoration so not the original Meade focuser. I did consider a Moonlite but could not justify the cost of the unit and mounting kit. This looked like the next best option and certainly seems to be a winner.First impression out of the box is that this a very solid good quality focuser, mounted on a heavy CNC base plate. Movement of the focus tube using the "Fast" knob on the Crayford is very smooth and gradual and the fine focus is almost imperceptible. It doesn't say this in the description but the focuser features an additional draw tube about 50mm long for eyepieces needing to be that little bit higher. The description also says tubes up to 15" my Meade 16 is closer to 18" diameter and this seems to sit nicely on the tube, so no issues from a tube size perspective. I did have to drill new holes and at first glance the position of the focuser seems to cover the lower 2 holes. This is easily fixed as base plate has 4 grub screws holding the focuser in place so easy to detach from the plate, mark and drill and then mount the focuser in place.I'd give this 5 stars but the 2" - 1 1/4" eyepiece adaptor is an odd slotted sprung steel thing which sort of does the job but doesn't fit a 2" filter too well. In order to work it needs to compress slightly which it doesn't do that well with a filter in place, also found it difficult to fit the filter in my nice warm dining room how that would go on a cold night is anyone's guess, fortunately I have a substitute adaptor.I can't say much about use as the clouds arrived when it did but trying it pointed at the church spire it's very smooth and easy to move but also very solid, looking forward to a clear night and being able to use all of my eyepieces for once,
