Building on the success of the original Explore Scientific 127 Triplet Apo and the Carbon Fibre versions, Explore Scientific now release their best ever value 5-inch telescope: the Explore Scientific ED APO 127mm f/7.5 Essential with Hex-Focuser.
The Essential series are "bare bones" versions of the Explore Scientific Apos - they still have the exquisite optics of the original triplets, including Japanese Hoya FCD1 Dense Fluorcrown and Explore's Special EMD™ enhanced multi-layer coatings on every optical surface for the utmost in colour-free performance and still have the high strength aluminium tubes, internal baffling systems and hyper-blackened edges for the ultimate in contrast. However, the Essential Series Triplets leave it up to you to provide Finders and other accessories - passing on the savings to you as a result.
The Explore Scientific ED APO 127mm f/7.5 Essential sports the new Hex-Focuser Rack and Pinion Focusers from Explore, featuring a hexagonal cross section to support a larger loads without the potential for "focuser sag" - and a 10:1 dual speed focus control as standard. In addition to this the optical tube assembly comes with Vixen-profile mounting bar and rings, featuring a handle with camera mounting rail.
Focal length: 952mm
Net weight 9.5kg w/o tube rings
Optical tube assembly with rings
Handle with camera mounting feature
Hex-Focuser with 10:1 reduction
The Explore ED127 Essential Edition telescope comes with a white aluminum tube with black accents.
Explore Scientific Air-Spaced Apochromatic Triplets have true APO optic and are diffraction limited at .25PV or better
Genuine ED (FCD-01) glass from Hoya Japan is used on all ED APO Triplets at Explore, for superb quality and light throughput
Enhanced Multi-Layer Coatings (EMD) are deposited on optical elements to boost contrast and eliminate light scatter; and contrast is further enhanced with the installation of matte black knife-edge baffles in the optical tube assembly.
While refractors seldom require additional collimation after initial factory adjustment, the lens cell design allows for consumer collimation. Sending your ED127 Triplet off to the factory is always an option, but is not required.
127mm models come with a heavy-duty 2.5" Hex-Focus focuser
Dedicated Field Flattener available as an optional extra in both 2 and 3-inch options.
