Product information "LUNT LS80MT/B1800R&P Multipurpose APO 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. 2-lens ED Apo telescope with FPL-53 glass, 80mm aperture and 560mm focal length - very good image quality for H-Alpha solar observation and also for observing the starry sky at night.

With innovative air pressure tuning system, good 2 inch (50.8mm) R&P focuser, and B1800 blocking filter.

Solar observing in H-alpha:
The LS80MT/B1800 is a complete telescope for observing the sun in H-alpha light, with 80mm free aperture (no central obstruction) and 560mm 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 R&P focuser with 10:1 reduction.
Blocking-filter is the B1800. The B1800 is very good for visual solar observing and also for photography.
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. With the additionally available conversion kit (item number 0551330) the 2-lens ED Apo refractor can then be used as a normal telescope with 80mm aperture and 560mm focal length for observation and photography of the night sky. The FPL-53 doublet lens offers an low colour aberration image. Common 2 inch star diagonals can be used at the high quality R&P focuser of the conversion kit 0551330.
Please note that the optionally available conversion kit 0551330 is absolutely necessary if the telescope should be used at night.

More applications:
With additionally available accessories the LS80MT offers even more possibilities!
- Double-Stack
The LS80MT telescope can optionally be upgraded with the additionally available double-stack module DSII/SFPT (item number 0551395). The DSII system is a internal double-stack module. 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-Light
If 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 wavelength
Certainly, the Ca-K filter modules from Lunt Solar Systems can also be used at the LS80MT to observe and photograph super-granulation and other effects visible in this wavelength on the sun.

This makes the LS80MT a completely universal usable ED Apo telescope of very good quality!

BRESSER Twilight I telescope mount with tripod

The Twilight I is a light-to-medium-duty alt-azimuth mount with tripod designed to quickly and easily accept small to medium sized refractors, such as the AR102 + AR127s or ED102mm + ED127, and of course, the ED80mm. Lightweight, fast Newtonians will also match up nicely with the BRESSER Twilight I mount. As long as your telescope does not exceed 18 pounds and has a Vixen-Style Universal Dovetail bar for mounting the telescope to the mount head, you are good to go. The Twilight I alt-azimuth mount head is made of powder-coated aluminum and there are worm gears on both axes. The adjustable angle head can be tilted forward or back at a 45° angle to allow more clearance for your telescope so you can point it straight up for viewing at the zenith. The Allen hex wrench for doing the mount head adjustment can be safely stored at the integrated magnetic holder. Slow-motion control cables are attached on the vertical and horizontal axes, and are easy to turn during the night, even with gloves on, due to the over-sized knurled knobs that are attached to the end of each cable. They can be attached to either side of each axis to accommodate right or left-handed users, or different types of telescopes (e.g. refractors vs. Newtonian reflectors) for ease of adjustment. The stainless steel tripod that comes standard with the Twilight I mount has adjustable legs and a wide foot print of 42 inches, which makes the tripod more stable. A spreader bar locks against the inside of the legs to secure the tripod even further, and keep vibrations to a minimum. SCOPE OF DELIVERYTwilight I Telescope MountStainless Steel Field tripod

Vixen AP-SM Mount with RA Motor Module and Star Book One Controller

The AP-SM mount is an enhancement of the AP mount. Unlike the AP mount, it has an RA motor and is equipped with the STARBOOK ONE controller. The AP mount provides a secure, stable support for your telescope. Thanks to the slip clutch mechanism, the mount can be adjusted quicky to the target object. There is a wide range of optional accessories. The ADVANCED POLARIS mount is ideal for both beginners and advanced observers who require a lightweight travel mount. STYLISH DESIGN The AP mount features an ultra-smooth finish without any projecting parts. Simply place your telescope on the mount and move it to the desired celestial object without having to loosen any clamps! QUICK POLAR ALIGNMENT The slip clutches allow you to adjust the telescope to your target object easily – no more searching for adjustment clamps in the dark! An optional polar meter is available, which enables you to locate the celestial pole when it is hidden by trees or buildings. OPTIONAL POLAR FINDER SCOPE The innovative polar finder scope provides a new way to polar align your telescope. Simply align the stars in the crosshair reticle with the same stars in the night sky. Polar alignment is achieved using 3 reference stars. The polar finder is illuminated to facilitate orientation and switches off automatically after 3 minutes to save battery power. POWER SUPPLY The RA and DEC motor modules are powered by four AA alkaline, Ni-MH or Ni-CD batteries. The RA motor module has a USB Micro-B port for an external power supply. A USB power pack or car charging cable can be used for longer observation sessions. STAR BOOK ONE CONTROLLER The STAR BOOK ONE is a multifunctional and intuitive controller that tracks in the RA and DC axis with a range of different speeds. The tracking options are designed for time-lapse cameras at a wide range of speeds, including sidereal, lunar and solar rates.

LUNT CAA-RF 0.8x reducer/field-flattener for nighttime photography with LS80MT, LS100MT & LS130MT telescopes

Field-flattener and focal length reducer for deep-sky astrophotography. Designed for the multipurpose APO telescopes of the Lunt-Solar-Systems LS80MT, LS100MT and LS130MT series.At the telescopes of the MT series from Lunt Solar Systems, the H-Alpha filter unit for solar observation can be removed, then these telescopes can be used as high quality ED APO's for observing and photographing the night sky.This accessory for the LS80MT, LS100MT and LS130MT telescopes shortens the focal length by a factor of 0.8x, providing a larger field of view for deep-sky astrophotography. This also allows shorter exposure times. At the same time, the field of view is flattened for photography.On the camera side, the reducer/field-flattener has a T2 male thread (M42x0.75). DSLR cameras can be connected here directly with a normal T2 ring.For other cameras, an M48x0.75 male thread is available in addition to the T2 male thread. The distance between reducer/field-flattener and camera sensor should be around 50 to 55mm.An M64x1 thread is provided on the telescope side. This allows to connect the reducer/field flattener to the focusers of the conversion kits for the LS80MT, LS100MT and LS130MT telescopes. Please note that for using the reducer/field flattener at the LS80MT, LS100MT or LS130MT telescopes, the corresponding conversion kit for night-time use of the telescope is absolutely necessary..FEATURESShortens focal length of F/7 ED telescopes by a factor of 0.8xFlattened field of view for photographyT2 thread and M48x0.75 thread for camera connectionWorking distance 50 to 55mmSCOPE OF DELIVERY0.8x reducer/field-flattenerAdapter to T2 thread (M42x0.75) and to M48x0.75
