Baader Planetarium’s guiding tube rings provide a very rigid stable platform for guidescopes or secondary (piggybacked) telescopes. The rings are supplied in pairs and there are three versions available to accommodate a range of telescope tube diameters:
- BPI: 60-120mm tube diameter
- BPII: 110-160mm tube diameter
- BPIII: 140-185mm tube diameter
They are produced from one-piece turned aluminium, have a width of 28mm and are anodised black. The bottom mating/mounting surface has a central photo-threaded ¼” connection hole and there are two addition through-holes 5 mm diameter. A further four milled planar surfaces with a photo-threaded hole are machined on the outer surface in order to be able to attach additional accessories to the rings or to connect several rings together!
Each ring has three M10 adjusting screws with 10mm diameter ball bearing bearing surface made of V2A steel. The tips are covered with a hard rubber sheath (i.e. the screw pressure surface does not rotate during the adjustment of the telescope!). With these rings, the guiding telescope is held absolutely solid, will not slip and will not be scratched!
