Revelation 12'' f/4 M-LRN Newtonian OTA
Zoom  Zoom

The Revelation 12" f/4 M-LRN Optical Tube Assembly OTA is the flagship of the Revelation Newtonian range, being both a capable imaging or widefield deep sky instrument. This remarkable instrument offers staggering light gathering power and diffraction limited optics. Being the largest of the Revelation range, we recommend either the Skywatcher NEQ6 or AZ EQ6 GT mounts as a suitable match for this instrument.

Revelation Newtonian systems are short focal ratio optical systems, which 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 B270 glass substrate, higher in quality than the usual Chinese-produced fair, 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.
