Precise helical focuser screws onto a male T-thread and accepts 1.25-inch fitting eyepieces and accessories.
An excellent choice for fitting a guide cameras to an Off Axis Guider with a T-thread.
Note: Helical focusers rotate, this needs to be be considered when used with cameras.
Perfect low cost enhancement to a Nexstar 130SLT. The focuser on the Nexstar is extremely coarse and hugely difficult to get a clear image at high magnification, but this makes it a breeze. Additionally, it replaces like-for-like the 1.25" eyepiece clamp and screws onto the Celestron supplied adapter, giving you a compression band clamp instead of the basic 2 screw holder supplied as standard. Fast delivery as well, so there's nothing not to like!
Great little focuser / 1.25" holder. Fitted to the T2 prism diagonal and then into the Celestron C6. Provides a better fine focus than the standard SCT focuser.Usual excellent Baader build quality. Something very satisfying with even the way the locking screws work. Its just a beautifully executed piece of kit.
Well made as expected. Bought it to go with Baader flip mirror. I plan to use eyepiece and camera so focused will allow me to set u both as parfocal. Worked well in my garden in daylight. Roll on a clear nighFLO service as always A1
This is a very useful and cost effective helical focuser which I bought to provide fine focus on a Zeiss Telementor II. The Zeiss focuser is perfectly useable but a only single speed and a little stiff in places. I fitted the Baader Helical focuser to a Baader Zeiss T2 Prism and now can coarse focus with the main focuser and fine tune by turning the eyepiece. The fact that it rotates when adjusting is not an issue for visual use with an eyepiece, so it is an excellent solution which doesn’t take any additional inwards focus. You can lock it in position if needed, and also use the most conveniently placed thumb screw to make fine adjustments. Finally it has a compression ring so won’t damage your eyepiece barrel. Excellent little product.
This focuser is ideal if you are using a SX Lodestar with the Atik OAG. It provides the means to obtain the correct back focus distance, which is difficult to achieve by other means.The build quality is very good, with a high quality black anodised surface, and the thumb screws work against the brass compression ring to provide a very secure fixing for the camera, but with no damage.Threads are nicely cut, as is the case with most Baader equipment, so screwing on and tightening feels robust.This has been a great solution to a problem and is highly recommended.
I needed this to fit a 1.25" eyepiece to the T2 connection on my 60mm Baader Variofinder. It works smoothly and precisely.
This is an excellent piece of kit. I bought it to improve the focusing on a standard Synta style R&P rather than go to the expense of a aftermarket Crayford. It works a treat, is lightweight & doesn't add much to the optical path. Moreover, it's very well made & has a really smooth action. It does rotate but if you're only using an eyepiece in it, then it doesn't matter.
