  • Guidescope rings BP I (2 pc)
  • With 6 large handknobs with screw and ball bearing tips
  • For tube diameter 60 - 120mm

Baader Planetarium - Guiding tube clamps with ball bearing bearing surfaces

Massive, solid, turned aluminium rings, width 28 mm, support surface with photo-threaded connection ¼ "and additionally 2 through-holes 5 mm diameter.

3 adjusting screws (M10) with 10mm Ø, ball bearing bearing surface made of V2A steel, covered with a hard rubber sheath (i.e. the screw pressure surface does not rotate during the adjustment of the telescope!). The guiding telescope is absolutely solid, non-slip and will not be scratched! A further four milled planar surfaces with a photo-threaded hole are installed on the outer diameter in order to be able to attach additional accessories to the rings on the outside or to connect several rings together!

True No-Marr Clamp Screws

The basic concept of guidescope rings remains unchanged since the dawn of the telescope. They consist of a simple ring with three radial machine screws arranged at 120 degrees, used to shift an auxiliary telescope to be aligned co-axially with the main instrument (or intentionally off axis for guidescope use). In this simplest configuration the three hard-pointed alignment screws bear directly against the tube of the auxiliary telescope, causing inevitable damage to the telescope's finished (painted) surface.

Surprisingly, most currently available rings have evolved little from this basic design, and subject your valuable equipment to repeated damage. The simplest and most inexpensive solution, taken by some manufacturers, is to add a small plastic cap or pellet inserted into the tips of the adjusting screws. While this significantly reduces the damage, the rotation of the plastic screw tip against the telescope can still noticeably abrade a painted finish (particularly if there is any grit embedded in the plastic tip). Also, often these plastic tips are made of too small a diameter, which result in high clamp loads that can permanently dent a guidescope tube.

The solution for this problem lies in enabling the plastic tip to freely rotate, so that as the clamp screw is tightened, the tip remains stationary relative to the telescope tube surface. The clamp screws on our guidescope rings are designed in just this way. Each clamp screw incorporates a large 12mm diameter nylon tip, in order to spread the clamp force and prevent permanent denting of a telescope's thin wall tube. The nylon tip is mounted onto the flanged head of a machined brass spindle, which inserts into a lubricated bore in the tip of the large diameter stainless steel clamp screw. The net result is a rigid, truly no-marr adjustable guidescope ring.

 ></div><h4>Modularity</h4><p>One of the distinguishing features of our guidescope rings is their ability to be interconnected with each other, or to easily attach other auxiliary equipment (finders, pointers, etc). Machined flats and mounting holes permit the rings to be assembled in a number of configurations, enabling you to mount and adjust multiple guidescopes, finder scopes, or other auxiliary instruments. These As shown in the image below, there are 5 locations around the periphery of each ring that have been machined as attachment points. Each location has a machined flat, and a central 1/-4-20 threaded hole. Note: In order to couple multiple rings, you will need to drill out one of the 1/4-20 holes with a 1/4
