The remarkably fast 200 mm f/4 parabolic primary mirror of the R200SS Newtonian reflector gives extremely sharp images with no chromatic aberration. The use of state-of-the-art coating technology yields the ideal surface for its f/4 primary mirror. The visual observer will enjoy wide views of deep sky objects. Actual groups of nebula or clusters can be viewed at the same time with this instrument.The telescope's large aperture and compact body make it ideally suited for astrophotography of nebulae star clusters and comets. The use of the optional coma corrector allows for a sharp coma-free image from edge to edge and the rack-and-pinion focusing mount with an adapter accepts 2 eyepieces.The R200SSDG comes standard with the 7 x 50 finder 232 mm tube rings dovetail tube plate and new focus design with more distance for photographic equipment as well as being a great match with the GPD2 mount.The GPD2 equatorial mount is the stronger and heftier of the GP mounts. With its solid steel R.A. and declination axes and brass worm gears this mount will hold up to years of heavy use. In order to assure accurate tracking for astrophotography the worm gears are especially machined to a very high precision that minimizes periodic error.The GPD2 holds almost 50% more weight than the GP2 and comes standard with tripod and counterweight. It is easy to use and functions well for both the visual observer and astrophotography. Motion is controlled by included control knobs for accurate slewing. The polar altitude adjustment varies from 0-degrees to 62-degrees in altitude.Technical data GPD2 Mount:R.A Axis: 144-tooth worm gearsDeclination Axis: 144-tooth worm gearsR.A. graduations: RA 10 min. incrementDec graduations: 2-deg. incrementsPolar Axis Scope: 6 x 20 wide fieldMount includes pre-installed variable intensity illuminatorPolar Axis Altitude adjustment 0- to 62-degreesCounter weight 1 x 3.7kg. and 1 x 1.9kg.Maximum loading weight 10kg.
