Large aperture, little focal length - guiding stars everywhere, even far away from the Milky Way!
As a finder, the optics offer between 5.3° and 5.8° when combined with our crosshair eyepieces. That´s enough for a good overview. By using eyepieces without reticle, you get a super wide angle telescope for comets and the band of the Milky Way with its star clouds and diffuse nebulae.
Features:
♦ 50 mm aperture, 205 mm focal length, focal ratio 1:4
♦ non rotating helical focuser for precise focusing. If optimal sharpness is reached, just tighten the locking screw. The star remains exactly on its position without tilting or shifting.
♦ 1.25" connection with brass compression ring and T2-thread
♦ for using an eyepiece, you need the adapter TST2-1-T2s or the extension tube TSVF1
♦ Standard quick release finder interface (for Vixen, Celestron, Skywatcher, GSO and many others).
Use of autoguiders with 1.25" housing, like ASI120MINI or Lodestar:
We simply recommend a good 1.25" adapter that screws onto the T2 thread. Suitable adapters are linked. Then the camera can be mounted easily, without focus problems.
Many cameras, like the ZWO MINI Guider, come with a 1.25" extension. With this you can also focus well. The extension should be turned out completely. However, you must not insert the camera completely.
