Focuser arrived! (Kugelblitz Telescope. Pt. 2)
This post was originally published on my old blog dedicated to amateur astronomy.
After 14 days waiting the focuser arrived. It’s one of the most important pieces in a telescope. I decided to go with the 1.25” barrel for lenses, as it’s cheaper and easier to find oculars to fit in. It’s a pretty popular choice as well.
This is a SkyLife Foc-3 Focuser, designed to curve around 150mm tubes. The center tube and some other parts are made of metal, but most of it is made with plastic injection molding, so I think it will be easier to grind the tube curvature. My tube is a 250mm one.
The overall finish is good, but this is not a high end piece. The inner tube will move when force is applied, so the weight of a DSLR may move the tube a bit, as it’s common with practically all focusers with that design. But the price tag is excellent, I got it for USD 15 / 150 BRL and I’m really happy with it.
