Optional Accessories lenses with blackened edges, rotating adjustable eyecups. Focal lengths from 5.5mm 1.25" to hugefield-of-view 30mm 2". • Xtreme Wide Angle: Xtreme Wide Angle Series 5000 Eyepieces use 9 optical elements to achieve a high contrast image with razor sharp correction all the way to the edge of the huge 100 degree Apparent Field of View. The lenses are Super Fully Multi-Coated with blackened edges in 2" diameter format. Three focal lengths, 9mm, 14mm and 20mm are all parfocal. • HD-60: The All New Series 5000 HD-60 Eyepieces have a large 60 degree Apparent Field of View that is flat and sharp to the edge, 17mm or more of eye relief for easy comfortable observing, Super FullyMulti-Coated lenses with blackened edges, rotating adjustable eyecups. Focal lengths from 4.5mm to 25mm.. Series 5000 Auxiliary Equipment Mounting System: All plates, rings and bases are precision milled from 6061-T6 Aircraft Grade aluminum, all joining surfaces are either precision chamfered or filleted to eliminate sharp corners and edges. Aluminum components are then carefully anodized black, and include stainless steel mounting hardware. Rings use three-point mounting with machined adjustment screws and include white colored Delrin® tips to prevent damage to scope finish. Bases for rings and counterweights include large lock knobs for easy adjustment. #62 T-Adapter: The T-Adapter is the basic means of prime-focus photography through all Meade SchmidtCassegrain and Advanced Coma-Free models. Thread the T-Adapter on to the rear cell of your telescope, followed by a T-Mount for your 35mm camera, and the camera body is rigidly coupled to the telescope. #777 Off-Axis Guider: The Off-Axis Guider provides a means during long-exposure astrophotography for the photographer to monitor the tracking of the telescope to assure that the telescope remains precisely positioned on the object being photographed. Like the T-Adapter, the Off-Axis Guider couples the camera body to the telescope but it also causes a small amount of the guidestar's incoming light to be diverted at a right angle, where the star's position can be examined for tracking errors with an illuminated reticle eyepiece; position corrections can then be effected using Autostar II. Piggyback Brackets: Piggyback photography is one of the most popular and easiest ways to get started in astrophotography. Attach your 35mm camera, with its own 35mm-to-250mm lens, atop your LX850 in equatorial mode, and guide the telescope using StarLock's narrow-field camera. Wide-field photos of the Milky Way showing remarkable detail and clarity can be taken. Dew Shields: In moist climates, water particles suspended in the atmosphere may condense on the front surface of the telescope's correcting plate. This dew formation may be inhibited to a significant extent by the addition of a dew shield, essentially an extension tube attaching to the front-cell of the telescope. #905 Variable Polarizer (1.25"): The #905 system includes two polarizer filters mounted in a speciallymachined cell, for glare-reduction in observing the Moon. Rotate the thumbscrew at the side of the unit to achieve light transmission between 5% and 25% of its original value. The #905 inserts into the diagonal mirror of the telescope, followed by an eyepiece. Cigarette Lighter Adapter: Powering the LX850 telescope by means of an automobile cigarette lighter plug. Astrometric Eyepiece: A high-precision 3-element achromatic eyepiece for a wide range of astronomical measurements. Measure double star separations, position angles, planetary diameters, lunar crater diameters and so forth. Includes variable LED illumination control and batteries.
