The Lunt 130MT Modular Day and Night is the complete telescope system. This refractor-based system has a precision-aligned triplet ED lens with a 130mm aperture, for truly stunning solar observation as well as beautiful nighttime applications.

The Lunt 130MT easily switches from Hydrogen Alpha (solar) configuration to its nighttime mode by removing its internal module. With the Lunt 130MT by your side, you won’t need anything else!

When configuring the Lunt 130MT, you must select a desired blocking filter that is inserted at the eyepiece end of the tube.  However, there is a range of additional options that make this telescope the complete system for daytime and nighttime viewing:

Blocking filter options

Which blocking filter you will require will be determined by how you are going to use the scope. The size of the blocking filter determines the size of the field you can see, and for large camera sensors, a small blocking filter may result in vignetting, meaning the corners of the sensor will not receive the required quantity of light.

• 12mm in a 2″ diagonal or straight-through tube configuration
• 18mm in a 2″ diagonal or straight-through tube configuration
• 34mm in a 2″ straight-through tube configuration

Focuser Options

The Lunt 130MT Modular telescope is currently supplied wth 2″Rack and Pinion focuser.

Feather Touch focusers are also available but due to the long lead times these are shipped separately. Contact Sidereal Trading if you equire a Feature Touch focuser.

Additional optional extras (sold separately)

Double Stack filter module

The Double Stack module narrows the bandpass for solar viewing from <0.65 Angstroms to <0.45 Angstroms. This enables you to see significantly sharper details on the sun and in the corona.

White light solar wedge

The white light (or Herschel) wedge is an optical method of passing all frequencies of light but attenuating (dimming) them, so the sun’s image is safe to view (with a Hydrogen Alpha filter). Most of the light is not sent towards the observer, but downwards to the bottom of the diagonal. This can make the diagonal hot to the touch.

Polarising filter for white light

A Polarising Filter will help control the brightness of the Sun’s image when using a Lunt White Light Wedge visually.

Calcium K wedge

A Calcium K wedge enables the viewer to observe the sun through an entirely different wavelength of light – near ultraviolet. This is especially suited to a camera as the human eye is not very sensitive to this frequency.
