Lunt 80 mm Universal Day/Night/Solar Modular Telescope - Advanced Package

This Advanced Package from Lunt Solar Systems unlocks the full viewing potential of their popular 80 mm ED refractor solar telescope. Along with the Lunt LS80MT 80 mm modular telescope, this package includes the accessories needed for solar, nighttime, terrestrial, white light, and calcium observing! In addition to everything in the Observer Package, the Advanced Package upgrades the blocking filter from B1200 to B1800 and includes a B1200 Calcium K filter! Observe the sun in H-alpha, white light, or Calcium wavelengths!

The included H-alpha and B1800 blocking filters provide a safe and exciting view of the sun's disk and surface. In addition, the white light wedge and polarizing filter allow for white light observing, and the included Calcium K module allows for solar viewing at the 393.4 nm wavelength! True doppler tuning allows for precise tuning. Removing and replacing the H-alpha module with the included backing plate and focuser transforms this 80 mm, FPL53 doublet lens refractor into a nighttime and terrestrial telescope.

Lunt Solar Systems LS80MT Modular Solar Telescope Specifications:

• Optical Aperture: 80 mm
• Etalon: Internal <0.65 Angstrom (single-stacked)
• Tuning: Internal Pressure Tune (Doppler True Tuning)
• ED Doublet Refractor (with FPL53 Glass)
• Focal Length: 560
• F Ratio: f/7

With a 560 focal length combined with the included B1800 blocking filter, the LS80MT is in an optimal configuration for solar imaging, in addition to more traditional astrophotography.

Included in the Advanced Package

• Modular Telescope with B1800 Blocking Filter - Featuring a 5.6 mm image size, f/7 ED doublet refractor with FPL53 glass optics, true doppler tuning, and a modular and portable design.
• 2-inch Diagonal and Adapter - Allows the LS80MT to accept both 2-inch and 1.25-inch eyepieces.
• 1.25-inch, 45-Degree Diagonal - Provides up/down correct and left/right correct and comfortable terrestrial viewing when compared to a 90-degree diagonal.
• Red Dot Handle and Mounting Ring Assembly - An integrated red dot finder and mounting ring assembly that doubles as a handle for additional portability.
• 6-inch Dovetail - For mounting.
• Backing Plate & Focuser - When the H-alpha and blocking filters are removed, the backing plate and focuser allows for non-solar nighttime and terrestrial observing.
• Lunt Zoom 1.25-inch Eyepiece - With an adjustable focal length of 7.2 to 21.5 mm, this eyepiece features the same 0.1% anti-reflective coatings that Lunt uses on its etalons. For use with solar, terrestrial, and nighttime observing (always have the H-alpha and blocking filters attached to safely look at the sun!).
• 2-inch White Light Filter - For imaging and observing in white light. For visual observing, this is best used in conjunction with the polarizing filter.
• Polarizing Filter - For controlling brightness when visual observing in white light.
• B1200 Calcium K Module - Allows for viewing at the 393.4 nm wavelength.

In addition, each Lunt Solar Telescope comes with a branded drawstring soft bag and aluminum-finished hard carry case with foam inserts!
