There are a few choices when it comes to focusers that can be used on the Lunt Solar Telescopes. This video will show you your choices and help you decide between the different choices.
Hi, I’m Faye Roman you Lunt Customer service representative. I’m going to talk about focusers.
Our smallest focuser is the helical focuser, and this goes on the LS50 telescope. It has a nice smooth turning range. A locking screw to keep you in place. All in all a nice little focuser.
If you desire something a little more heavy duty on the LS50, we offer a 1.24″ feather touch focuser. This has a 1:1 focusing mechanism for nice precision focusing. It also employs a locking screw to keep you in place when needed.
Our LS60 and LS80 with come standard with a Crayford focuser. That’s the focuser here. The Crayford has a 10:1 corse to fine focus. It also has a locking screw to keep you in place when needed if you are using a heavy eyepiece or camera. It’s a good standard focuser and can handle most applications.
If you desire something a little more heavy duty we also offer the Starlight feather touch. The feather touch will also give you a nice fine and corse focus. It also offers a locking screw when needed. What you’ll find with the feather touch is a bit of a smoother travel and a more heavy duty design. This is sometimes desirable when you are using heavier equipment. If you’re getting an LS100 or LS152, this will be standard on your package.
