## Customer Reviews

### ⭐⭐⭐⭐⭐ Good quality and decent price
*by A***R on January 21, 2025*

Nice upgrade for an old focuser on my 1950’s Newtonian

### ⭐⭐⭐⭐⭐ Very smooth and tight alignment
*by B***S on March 15, 2025*

Fixed all of my alignment issues. My previous focuser that came with my telescope had a lot of slop in it, so always had trouble aligning. This new focuser completely fixed that. I had to make an adapter plate to fit it on my Celestron StarSense dx 130az, but I have had the best views of Jupiter to date in the last 2 days, with very sub-par viewing conditions.

### ⭐⭐⭐⭐ All Metal replacement focuser with some minor flaws
*by P***U on January 20, 2021*

Plus for all metal construction. Curve on plate is for a 5 inch tube. I have a 4 1/2 inch tube and needed to make a spacer to fill the gap between the tube and the focused. The focus adjuster was very loose and wobbly. Strap that holds the adjuster knob shaft is poorly designed and doesn’t do the job properly. I was able to tighten in up by bending the straps so it pushes the shaft closer to the gear. The strap is made of thin steel and this should have been done at the factory or a better tighter fitting part made. Once tightened it seemed to work acceptable but it might loosen again over time. Tension locking screw on adjuster is a nice feature that OEM adjusters don't have. Good product with some flaws which can be fixed with a little effort. The draw tube and gears are all metal which is nice.
