Fits into 2" focusers, (threaded for 2-BLA)

The stock Meade Lightbridge telescope is balanced to accommodate a small eyepiece and red dot finder. Once the user begins to add heavier eyepieces and finders, the telescope becomes very front heavy. These weights replace the push or locking screws on the mirror cell, making them a bolt-on addition. This "core" set properly balances the telescope for use with a large 2-inch eyepiece and a finder scope or Telrad.

This 35mm camera lens adapter mates the STL series cameras with Nikon 35mm camera lenses for wide field imaging.

Key features Farpoint

• System works in daylight or and night with the aid of a dim astro-flashlight aimed down the telescope tube
• Grip ring is knurled for a sure handhold
• Each chesshire is machined from aircraft grade aluminum on precision CNC lathe to exacting tolerances
• Model: Farpoint Far Reflective Cheshire Collimator, 2" with Four Primary Mirrors, Red

Far Point FP261 is Far Reflective Cheshire Collimator red in color. The chesshire collimation device is the simplest, most intuitive tool for adjusting the primary mirror collimation in a Newtonian telescope system. In addition, the chesshire is relatively insensative to wiggle or slop in the focuser. Using the cheshire in conjunction with single beam laser collimator is suggested. First use the laser to adjust the alignment of the secondary mirror, then adjust the primary mirror alignment using the cheshire. Farpoint makes the cheshire in 1-1/4 and 2 inch sizes. Each chesshire is machined from aircraft grade aluminum on precision CNC lathe to exacting tolerances. They are then polished and hard anodized for a superior appearance and durability. The grip ring is knurled for a sure handhold. Each cheshire includes four primary mirror marking triangles and an alignment template for applying the triangles onto mirrors up to 12. [+]

The Farpoint FP-320 12" Primary Mirror Collimation Upgrade Kit replaces the stock knobs and springs. High quality aircraft aluminum is turned on a state of the art CNC lathe. The finished knurled knob is precision anodized in an attractive blue that matches the official Meade color scheme. Farpoint's replacement springs are much stiffer than the stock springs. With Farpoint's springs, the use of the stock "lock bolts " for the mirror becomes a thing of the past.

Your telescope's focuser is used to compensate for your near- or far-sightedness; DIOPTRX compensates for your astigmatism. These units attach and lock onto the tops of over 20 long eye-relief Tele Vue eyepieces to achieve the sharpest full-field viewing possible. DIOPTRX models are available in 1/4 diopter steps, from 1/4 up to 3. 5 diopters, and are rotatable for tuning to the best orientation. A series of engraved letters on the barrel helps to monitor orientation. Simply choose the DIOPTRX model that matches your eyeglass prescription for astigmatism. All lenses are multi-coated glass in anodized aluminum housings with rubber eyeguards The visual experience in astronomy is maximized by stripping away limitations: the limitations of the observing location (dark skies and steady seeing) the limitations of the telescope (aperture, field, resolution and contrast) the limitations of the eyepiece (field, resolution and contrast) the limitations of our eyesight (e. g. , astigmatism) Tele Vue has historically been dedicated to overcoming the first three of these limitations: with wide angle, flat field telescopes easily portable for traveling to great observing locations matching ultra-wide angle eyepieces with full field image quality to generate what we call "spacewalk" viewing and a variety of long eye relief eyepieces to allow eyeglass wearers to enjoy the maximum visual experience To overcome the fourt.

Key features Lumicon

• "The Horsehead Nebula Filter"...
• Model: Lumicon 1.25" H-Beta hydrogen spectrum Filter for 1.25"

The Lumicon H-Beta Filter isolates only the Hydrogen-beta line of the spectrum (486. 5nm) while blocking, completely, the rest of the overall spectrum of light. The result is extreme contrast between the black background and the delicately attenuated H-beta light needed to view a few select, extremely faint objects such as the Horsehead, Cocoon and California Nebulae. In may cases the Lumicon H-beta Filter is the ONLY way to view those objects. A steady, transparent sky, 8" or larger aperture (in most cases) and a maximum-efficiency exit pupil (7mm), combined with the Lumicon H-beta Filter, all make an unbeatable combination for viewing those "notch in the belt" objects. Lumicon measures every filter individually on a Perkin-Elmer Double-Beam spectrophotometer, inscribing on the filter its % transmission for the primary H-beta Line. Not intended for photographic use.

This adapter mates Canon T-rings with Imaging System Accessories. Eliminates the inner portion of Canon T-rings to provide a larger diameter opening for reduced vignetting.
