Butter soft. That's what you will feel as soon as you rotate the fine control of this focuser. Immediately after you think "heavy" that is. Because it is heavy and that's something to expect due to the full metal robust construction of this item. The fit is excellent and the workmanship is something to admire as soon as you remove it from the big padded box that protects it well. The black glossy finish of the 2" focuser and the 1.25" adapter are beautiful and look perfect together.

It is the first accessory that I added to a new Celestron C8 advanced SGT due to previous bad experiences I had with the focusers of other cheaper telescopes. This piece comes with compression rings on the 2" side as well as the 1.25" adapter. It features a thumb screw on the bottom that locks the movement if you wish. I think that this is done to protect the settings for astrophotography. There is also another thumb screw on top near the ring that attaches to the scope. This screw helps with the alignment of the focuser, in the sense that you can rotate the whole focuser and everything that is attached to it without unscrewing it from the scope.

The movement is just 1-inch long but the overall focuser will add 3 to 4 inches of length to the optical path of the SCT. Not a big deal, SCTs can take more than that. The weight of the focuser on the other hand can be an issue if you plan to attach a lot of equipment on the scope and subsequently the tripod. None of this is an issue for the C8 SGT. The two work fine as if they were made for each other.

Zhumell does make good products and this is one of them. The price was right too. Get one, you will be glad you did. By the way, it looks that you can motorize it if you are handy.

Product arrived timely and well packaged. However it was completely unusable out of the box. The focus would not work - the main tube simply would free fall out of the housing. When I did try to turn the focusing knobs it would make an awesome grinding sound. Since it did not come with any instructions I had to mess round with what appeared to be the adjustment screws. I was able to get it working but it still doesn't seem very smooth. it still "catches" while focusing in/out. The true test will be how it performs in actual service, but for now I am not satisfied that the product is performing as expected. It does seem to be well made, but thus far doesn't perform as good as it looks and feels.

Comments about Zhumell SCT Dual Speed Telescope Focuser:

I was very pleasantly surprised when I received the Zhumell dual speed SCT focuser. It's huge, kind of heavy and it seems to be quite bomb proof. I can't believe that it was so inexpensive. Excellent quality at twice the price!

    Q1: Will this work a Meade LX90?

    A: Yes. The Zhumell SCT Dual Speed Focuser is fully adaptable to your Meade LX90.

    Q2: What is the diameter of the threaded end that attaches to the telescope?

    A: It comes with an adapter so the diameter will either be 1.25inch or 2inch depending on what will work with your scope.
