Revelation 8" f/4 Carbon M-LRN OTA Extended Sale!  Get this excellent scope for £499 (Was £633).  Save £134!


The Revelation 8" f/4 CARBON M-LRN Optical Tube Assembly OTA has the same high-quality mirror set as the standard steel-tubed Revelation 8" Newtonian, but this version comes with a high-strength, super-lightweight Carbon Fibre tube.  This leads to substantial weight savings (nearly 1.5kgs) over the regular version, putting less stress on mounts and also provides some gains in regulation of thermal equilibrium in the tube.

Revelation Newtonian short focal ratio optical systems are very respectable performers for many different types of astronomical observation but are particularly well suited for astrophotography.  Featuring Parabolic mirror sets made of low-expansion BaK7 substrate, higher in quality than the usual Chinese-produced fare, these Newtonian systems offer the user excellent optics and top-notch build quality at extremely reasonable prices.

The Revelation Newtonians come with ultra-thin secondary mirror supporting vanes, substantially reducing diffraction spikes. These Newtonians feature a 2" fitting (with 1.25" step-down ring), 1:10 geared ratio, graduated Crayford focuser for precise focus, with a 35mm extension tube to ensure the attachment of a whole host of visual and photographic accessories. The focuser will also take up to 5kgs of accessory load. Also included with all the Revelation Newtonian range are a lovely 8x50 detachable finderscope, quick release tube rings, with a Vixen/Synta-style dovetail bar for easy attachment to numerous commercially available mounts and a 12v Primary mirror cooling fan in order to help reach optimum observing/imaging temperature as quickly as possible.
