Orion Helical Focuser

Can anyone provide feedback for the Orion Helical Focuser?

Thanks,

Mike

Not on the Orion, but on something similar. I had another version (can't recall the maker's name, now) that I purchased because it appeared a little better made. It did seem to allow for a somewhat finer focus, but in turning the whole eyepiece/focuser assembly it imparted enough wobble to the telescope at high powers that it also made it harder to achieve that exact focus. And this was on a stable dobsonian mount! Was it worth it? Well, I sold mine, but if you have a very stable mount and a steady hand, it might improve your focusing ability. Personally, I think you would be better served by upgrading to a two speed focuser, if you can afford it. Hope that's helpful to you.
