Telescope for nighttime observation and photography

The LS60MT Telescope provides solar viewing in its default configuration with provided Hydrogen Alpha Module, its 60 mm aperture allowing the viewer to gaze at the sun with an unobstructed clarity that is unparalleled in the industry. Explore the intricacies and features present on the sun with amazing detail utilizing our doppler true tuning pressure system; this will allow the viewer to change their view of the sun with the finest of adjustments, by simply adjusting the pressure within the system. The Lunt LS60MT can be use alongside some of your favorite accessories during the night or day! With its newly updated optics, you can watch as the features virtually protrude from the sun and see our closest star as you never have before, in all its splendor.

LS60MT Nighttime Telescope

A truly portable powerhouse telescope, the new Lunt Solar Systems LS60MT is certainly the choice for you. Easily configurable, the 60MT will provide the excellent Hydrogen Alpha viewing capabilities that Lunt Solar Systems is known for world wide, while optional accessories will give you the possibility of continuing your observation with White Light, Calcium K, Terrestrial and Night Time viewing at 70 mm aperture! Explore the majesty of the Sun´s prominences, filaments and other surface phenomena during the day, and when the Sun finally sets, switch to wandering through our Galaxy at night with minimal effort. The 60MT has been designed with ease in mind, ensuring your transition from daytime to nigh time viewing in mere minutes. Equipped with an ED doublet lens and an extremely capable 2" Crayford focuser, the LS60MT is sure to delight in any configuration! Whether Hydrogen Alpha, White Light, Calcium K, or night time and terrestrial viewing, the 60MT can do it all!

True Doppler Tuning

Importantly, True Doppler Tuning allows for a shift into and away from the user, adding a 3-D like component to the viewing experience. To be sure, it has minimal effect on prominences due to their location at the edge of the disk, but it does have an effect on filaments and likewise the active regions on the surface. Also while looking at a filament at the center of the Sun, the user has the ability to Doppler shift from the base of the filament to the tip. In this way following the filament through its structure toward you and away from you. Amazingly, this allowing for enhanced visual and imaging capability for the observer as well as a research tool for the avid hobbyist. In addition the pressure tuning system provides an order of magnitude more precision to the tuning of the desired features.

Additional information: What is the "Pressure Tuner" system?

The air pressure in our atmosphere varies depending on whether you are at sea level or, for example, on a mountain. The different conditions influence the wavelengths of light. Although this shift is minimal, it is clearly visible with filter bandwidths of less than one angstrom. If the filter is no longer precisely adjusted to the (shifted) H-alpha wavelength, the image of the sun in the telescope becomes blurred, and prominences and surface details are no longer visible.

The etalon filter systems must therefore be adapted to the conditions prevailing at the observation site. This correction, known as "tuning", is usually achieved by mechanically tilting the filter. With dimensions of just a few angstroms, it is of course not easy to achieve the required correction precisely by tilting. Because the filter is then no longer exactly straight in the light path, optical errors can also occur.

The "Pressure Tuner" air pressure system from Lunt Solar Systems takes a different approach. The etalon filter is no longer tilted; instead, the air pressure in the filter system is changed. Starting from the ambient pressure at which the etalon is set to a red-shifted H-alpha line, the tuning system can be used to compress the air surrounding the etalon. This changes the refractive index and shifts the transmission wavelength toward blue, enabling precise adjustment to the actual current wavelength within a range of +/- 0.4 angstrom.
This allows for much more sensitive adjustment, and the surfaces of the etalon always remain at the correct angle in the beam path.
