SED1005 Resolving Power of a Telescope

Resolving Power of a Telescope Resolving power of a telescope is defined as the reciprocal of the smallest angle subtended at the objective lens of the telescope by two point objects which can be just distinguished as separate. Features: Modular approach. Orientation and Height of Sodium Light source is adjustable. Bridge type microscope can be used vertically and horizontally. Objectives: To determine the resolving power of a telescope. Technical Data: Type : Travelling microscope Main scale : Range 0 -170mm, 1 MSD 0.5mm Vernier LC : 0.01mm Magnifier : FL 50mm, dia. 25mm Eyepiece : Ramsden 10X Objective : 3X Lamp (sodium) : Mild Steel, 200 x 85mm (LxØ), slit Ø3mm Lamp power : 20W, input 220V AC Reflector ass. : PVC, 105 x 100 x 110mm Fuse : 2A Rotation : 120 x 80 x 1.2mm Lens housing : 80 x 38mm(Øxh) Micrometer slit : Range 0 – 3mm, LC 0.01mm Telescope : Eyepiece 10X, Slide type (Focussing), 10mm dia.
