Περιγραφή
A Guidescope is very important in long-exposure astrophotography in order to continuously compensate for periodic tracking errors of the mount.
The UltraGuide MKII from Artesky is a 60mm Guidescope with a focal length of 240mm and thus ensures a fast aperture ratio of f/4 – ideal as a guide tube for optics with medium or short focal length.
The 1.25″ Helical focuser allows you to use the UltraGuide MKII both as a high-quality viewfinderand as a guide tube.
It is equipped with a T2 thread to allow the connection of most cameras on the market.
The helical, rotatable focuser is the great strength of this Guidescope, because it allows two types of focusing:
A less precise overview (search function) and a micro fine adjustment for the right precision as soon as you have found a guide star.
The back focus offers a very comfortable focus position – both with high-quality eyepieces, as well as with most guiding cameras on the market (e.B. QHY, ZWO, Omegon GUIDE, etc.).
Thanks to its rotatable focuser, the UltraGuide MKII 60mm always retains the correct orientation of the camera used.
The camera does not rotate and this function is essential for correct use with autoguiding software (such as PHD).
Included in delivery are two 80mm guide tube clamps and three screws with nylon tip, as well as a short Vixen (GP-Level) dovetail rail,which allows connection to most common viewfinder shoes with the standard profile.
Alternatively, you can simply connect the whole set to a prism clamp and attach it to any Vixen or Losmandy rail.
