Model: baader-2458125Part Number: 2458125Brand: Baader
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.
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.
