Product information "LUNT LS7-21ZE Zoom Eyepiece 7.2mm - 21.5mm"

Lunt Solar Systems zoom-eyepiece with variable focal length from 7.2mm to 21.5mm, with 1.25 inch (31.7mm) connection.

The special of this zoom eyepiece is that the optical layout offers highest quality views of the sun, but also on nightsky objects. LUNT minimized the reflections by using superb multicoatings and with care designed internal baffle system and blackened lens edges. The LUNT zoom-eyepiece is not the widest field zoom-eyepiece on the market, LUNT prefered best performance over widest field. The sun and stars are perfect pin point across the entire field of view without any visible distortion. The LUNT zoom-eyepiece is almost parfocal, from one end to the other end of the zooming way you need only 0.5mm to refocuse. The LUNT zoom-eyepiece has a very nice height adjustable eyeguard to protect your eye against day light reflections and to help you to find the perfect eye position.

Please note that these eyepieces are only accessories for existing solar telescopes or filters when observing the sun. Solar observation alone with these eyepieces without additional solar filters is not possible!

Warning notes

Safety instructions: There are certain dangers when observing the sun, regardless of the telescope used. Lunt-Solar-Systems places great emphasis on the safety of their products during manufacture. Your safety is the highest priority, and we ask that you carefully read the telescope manual before beginning solar observation. Please never disassemble the telescope! Never use it if it has been modified or damaged in any way! Always contact our customer service if you have any questions regarding the safety of your instrument. Never look at the sun with an unprotected eye or with a telescope not intended for solar observation! Never leave your telescope unattended while it is pointed at the sun! Other people who are unfamiliar with it might attempt to replace the block filter with another prism, unaware of how critical this filter is for safety. The components of Lunt-Solar-Systems telescopes are not interchangeable with those of other manufacturers. Lunt-Solar-Systems solar telescopes contain several different optical elements that have been precisely adjusted and mounted during manufacture. These systems require no maintenance. Never disassemble the telescope. Doing so will void the warranty, potentially leading to expensive repairs, and may cause future damage to your instrument, compromising your safety! Most Lunt-Solar-Systems telescopes and filters include a very sensitive optical component called an Etalon. These Etalons are built into the system to protect them as best as possible. Countless considerations have been made to ensure the best performance of this "heart" of every system, even under the daily stresses it inevitably faces, such as shocks and vibrations during transport or regular use. Nevertheless, it should never be dropped. Improper use of the telescope can damage the Etalon (not a warranty case) and render the system unusable until repaired. The instrument should always be stored in its original packaging or in the optional transport case (item number 0554010). Like any optical precision instrument, it should be stored in a dry environment. With proper care, you will enjoy your instrument for a lifetime!

Explore Scientific ReflexSight LED Finder

A new take on a classic design, superior to the usual red dot finder - which will fit many telescopes and larger binoculars.Explore Scientific ReflexSight™ LED projection viewfinder, uses proven functionality with versatility, while having enhanced performance features.Looking through this viewfinder shows multiple deep red target circles projected against the night sky. Both eyes can be used for quick and easy star hopping, in order to target objects in your telescope. The big advantage is that you can see the entire night sky without magnification and not just a small section of the sky, as you would through a magnified finderscope. This makes Goto aligning quick and easy and speeds up acquisition of targets.New "Multi-Dot" target circle pattern (in standard circle diameters of 4.0 degrees, 2.0 degrees and 0.5 degrees), prevents blocking of stars within the field of view. Using the widths of the projected circles as reference points allows those users with non-goto telescopes to easily work out the location of non-visible targets, with reference to more easily visible stars. The projection screen size is a generous 55 x 35 mm.Multiple mounting options. The Explore Scientific ReflexSight™ LED projection viewfinder's base fits standard "Vixen-style dovetail" finder bases, allowing the user to attach this finder to a wife array of commercially-available telescopes, without modifying the telescope itself. A ¼ inch x 20G threaded adapter (photo tripod thread) is built into the finder base, allowing the finder to be attached to a variety of telescopes, via piggyback camera adapters with a photo tripod threaded hole.Functional design and intuitive use: the smooth housing, with no sharp corners, prevents snagging. Easily accessible battery compartment, taking 2x standard AAA alkaline batteries (not included), which power the frugal LED illuminator. The low power consumption of the LED lighting ensures a long operating time. Large, continuously adjustable brightness control with knurled knob head can be easily operated with gloves. Click the rotary switch to turn off completely. Rear-facing, tool-free three-point parallax knurled collimation knobs, again, easy to operate even with gloved hands, ensure you are well locked-on to the main optical axis of your telescope. The projection screen is coated, to minimise annoying reflections and allow you to concentrate on the finder's target and the night sky behind it. Comes complete with screen and optics cover. The extremely compact design allows mounting even on small, lightweight telescopes - truly a finder for all!FEATURESReflexSight LED projection finder with deep red target circles Standard circle diameters 4.0 degrees, 2.0 degrees and 0.5 degreesProjection screen size: 55 x 35 mmFits standard Vixen-style dovetail finder shoes There is also a ¼ inch x 20G female photo tripod thread in the base Can be mounted via piggyback camera adapters etc. Operates on standard AAA batteries (not included) Smooth housing with no sharp corners, prevents snagging Comes complete with optics and screen cover Compact design and easily accessible battery compartment Large, continuously adjustable brightness control with knurled knob Click switch to turn off completely Tool-free three-point collimation parallax adjustment with easily accessible knurled knobs Can also be mounted on small and light telescopes WHAT'S INCLUDEDReflexSight LED projection finder

LUNT LS60MT/B1200R&P Multipurpose ED Telescope for Sun + Night-Sky

Modular designed multipurpose telescope, both for observing the sun in the H-alpha wavelength, as well as for night sky observations. Easy conversion between the different applications with a few simple steps. Excellent image quality due to 2-lens ED optics with 70mm aperture for night sky observation, and 60mm usable aperture for H-alpha solar observation.With innovative air pressure tuning system, high-quality 2 inch (50.8mm) Rack&Pinion (R&P) focuser, and B1200 blocking filter.Solar observing in H-alpha:The LS60MT/B1200 is a complete telescope for observing the sun in H-alpha light, with 60mm free aperture (no central obstruction) and 420mm focal length. The H-alpha wavelength is the most impressive way to observe the sun, showing protuberances at the sun's edge, filaments and flares on the surface, and much more. An internal Etalon filter achieves a bandwidth of <0.7 Angstrom with the innovative air pressure tuning system Pressure-Tuner. Tuning is done by slightly changing the air pressure in a pressure chamber inside the telescope. This changes the refractive index of the air, making it easy to tune to the H-alpha line. The pressure tuner guarantees a homogeneous image, without central obstruction, and a permanently protected Etalon without erosion. A set of collimating lenses installed in the telescope ensures best performance.Fine adjustment is achieved with a solid 2 inch Rack&Pinion focuser with 10:1 reduction.Blocking-filter is the B1200. The B1200 is very good for visual solar observing, and also for solar imaging.The star diagonal in which the blocking filter is installed, is equipped as standard for 1.25 inch eyepieces and with a T2 camera connection.Observing the starry night sky:The H-alpha Etalon system can be removed from the telescope in a few easy steps thanks to its modular design. The 2-lens ED refractor can then be used as a normal telescope with 70mm aperture and 420mm focal length for observation and photography of the night sky. The ED Doublet lens will offer an excellent image. It can be used with a standard 2 inch zenith mirror or other accessories at the R&P focuser, the back focus is 135mm.With an additional Amici prism, the telescope can of course also be used during the day for nature and landscape observations.This makes the LS60MT, with its small dimensions and low weight, also an ideal travel telescope for all applications!More applications:With additionally available accessories the LS60MT offers even more possibilities!- Double-StackThe LS60MT telescope can optionally be upgraded with the additionally available double-stack filters LS50FHa or LS60FHa (part numbers 0550200 and 0550250). These filters will be simply screwed on the front of the LS60MT, no additional adapters are necessary. Thereby a bandwidth of <0.5 Angstrom is achieved for H-alpha solar observation. Therefore much more details on the solar surface will become visible.- Solar observing in White-LightIf the H-alpha unit has been removed, of course either a sun filter to be installed in front of the objective, or a Herschel-wedge at the focuser can be used to observe the sunspots in White-Light.- Solar observing in Ca-K wavelengthCertainly, the Ca-K filter modules from Lunt Solar Systems can also be used at the LS60MT to observe and photograph super-granulation and other effects visible in this wavelength on the sun.This makes the LS60MT a completely universal usable telescope!FEATURES2-lens ED refractor, FPL-51Aperture: 70mmUsable aperture in H-alpha: 60mm (no central obstruction)Focal length: 420mmBandwidth: internal Etalon with <0.7 AngstromTuning: air pressure tuning system Pressure-TunerBlocking filter: B1200 with 1.25 inch and T2 connectionFocuser: Rack&Pinion focuser with 10:1 reductionTube-ring with 1/4-20 tapped base (standard thread for photo-tripods)Weight with H-alpha unit: 3.8kgWeight without H-alpha unit: 2.6kgLength with H-alpha unit and blocking filter: 40cmLength without H-alpha unit: 31cmSCOPE OF DELIVERYLS60MT Multipurpose TelescopePressure-TunerB1200 blocking filter in star-diagonal housing2 inch Rack&Pinion focuserTube ring with 1/4-20 connection for mounting on photo-tripodsTransport case (53x33x17cm)Instruction manual
