  With its 44% increase in light grasp and image brightness compared to the ED127 Air-Spaced Triplet, and 125% increase compared to the ED102 Air-Spaced Triplet, the ED152 Air-Spaced Triplet FCD1 Series in Carbon Fiber is a research-class instrument, ready for high-productivity assignments.

  Observe moon transits with their shadows across the face of Jupiter, as well as structural detail and color variations within the wake of the Great Red Spot and at the boundaries of numerous equatorial cloud belts; resolve Cassini’s and Enke’s Divisions of Saturn’s rings and substructures within the rings themselves. Nebulae stand out in splendid detail, giving one the impression they are looking through a much larger aperture telescope, with filamentary structures observable even under less than optimal seeing conditions. The ED152 Air-Spaced Triplet FCD1 Series in Carbon Fiber is a true work-horse optical instrument ready for any observing or imaging requirement.

  The Bresser classic 4" achromatic refractor will introduce you to a plethora of Earth's most influential neighbors! Drop by Saturn and see his famous rings with your own two eyes, or visit Jupiter, who boasts the largest planet on the solar system's block. If you have a mind to do it, you can get to know the Moon like the back of your hand. 

  The Messier 102mm telescope uses a two-element, air-spaced crown & flint glass objective as its light-gathering source. The optics are fully anti-reflection coated for contrast and sharpness. To help increase contrast even further, the optical tube assembly has a long dew shield installed. A 2" rack and pinion focuser is included with this telescope. The draw tube is etched with a millimeter scale to help with repeatable focusing performance and the focuser is made with brass compression rings so that accessory barrels are not marred by a rogue set-screw. Additional accessories include an eyepiece and diagonal. 

  A one-piece tube ring assembly cradles the optical tube and makes mounting your Messier 102mm telescope a breeze. At the top of the tube ring, you'll find a built-in carry handle that is designed with the ability to attach a DSLR camera for piggyback astrophotography. At the bottom of the assembly is a stainless steel rail that slides into Vixen-style mounts.
