Product Description

LUNT ENGINEERING - 152mm f/7.9 ED APO Refractor

Lunt Solar Systems has long been recognized worldwide as the pre-eminent leader in solar discovery and imaging telescope development. Now the company has entered the field of "nightime" discovery by introducing a line of equally high quality ED APO refractors in 70mm, 80mm, 102mm and 152mm apertures all under the brand name of Lunt Engineering.

The Lunt Engineering 152mm ED APO doublet was designed by APM Telescopes and is a trendsetter in the 6” Refractor category. It has been painstakingly engineered to provide the optical and mechanical quality astronomers would expect from APM, but at a surprisingly affordable price. The 152mm ED APO telescope features a doublet lens cell that uses specialized (Chengdu CDGM FK61 and Lanthanum H-LAF53) ED glass equivalent to FPL-51 with a Lanthanum-coated element included to maximize performance.  As further proof regarding the quality of the optics, an interferometry test at the 532nm (green) wavelength is performed on any new telescope before it ships from the factory. 

With a full 1200mm of focal length, the Lunt Engineering 152mm ED APO is an impressive all-around telescope. From intricate double star observations to high contrast detailed planetary views, this scope will introduce a whole new group of Astronomy enthusiasts to just what a high-quality refractor can do.

The Lunt Engineering 152mm ED APO telescope is supplied with all of the accessories you will need to start observing.*  Inside the quality aluminum transport case you will find a newly designed 2.5” focuser, CNC tube rings incorporating a carrying handle, a Losmandy-style dovetail, a 2” Star Diagonal and a finder bracket. *All you need to do is add an eyepiece, a finder scope and a heavy-duty mount.

The 2.5” focuser is a Rack and Pinion type with 1:10 fine focusing. It remains rigid under high loads, making this heavy-duty focuser very suitable for imaging. The 2” and 1.25” eyepiece adapters use a newly designed collar clamp, which will provide considerable improvement over brass compression type adapters. Although the standard focuser is great for imaging, a Starlight Instruments Feather Touch (model FTF3035B-A) is available as an optional upgrade. If the user already has a Starlight Instruments FT focuser, the tube end has the required M109 x 1 and M95 x 1 threads to accept a 3” or 2.5” Starlight focuser as well.

Other optional imaging accessories for the 152mm ED APO include a 2.5” field flattener, which maintains the focal length of the telescope, as well as a dedicated Massimo Riccardi designed focal reducer. The reducer changes the focal length by a factor of x0.75, yielding a 900mm focal length and fast f/5.9 focal ratio.

The Lunt Engineering 152mm ED Apo can also be used for White Light or CaK imaging with the addition of the proper filters or accessories. The Lunt Engineering logo is used on these scopes to differentiate them from dedicated H-alpha solar telescopes with the Lunt Solar Systems logo. Lunt Engineering is a division of Lunt Solar Systems, and these products can be used with LUNT Solar Systems solar products or as supplied for standard nightime use.
