100mm Solar Telescope

100mm – Solat Telescope OTA

General Features:

The Lunt 100mm Hydrogen-alpha Solar Telescope  is an advanced solar system. This refractor-based system has a precision-aligned doublet ED lens with a 102 mm aperture. The focal length is 714 mm, for an f/ratio of 7. Course focus adjustment is via a slide tube. Fine focusing is achieved with either a standard Crayford style Focuser with 10:1 reduction (for standard Visual use) or a high precision 2″ Starlight Feather Touch  focuser with 10:1 reduction (Recommended for Visual & Imaging).

The basic configuration of the 100mm Solar Telescope is as follows:

  • 100mm Solar Telescope Optical Tube Assembly (unobstructed)
  • Doppler True Pressure Tuning
  • 12mm Diagonal Blocking Filter
  • Crayford Style Focuser with 10:1 Fine Adjust
  • Integrated Mounting Rings with 1/4-20 Mounting Holes and Sol-Searcher Attachment
  • Shipped in Custom Foam and Standard Hard Case

Additional Upgrades and Accessories are available at additional cost.

The price shown for an upgrade is the value of that upgrade over the base product and not the price of the upgrade product if purchased separately.

An internal etalon with Doppler True Tuning adjustment allows for a <0.7 Angstrom bandpass.True Doppler Tuning allows for a shift into and away from the user, adding a 3-D like component to the viewing experience. While it has minimal effect on proms due to their location at the edge of the disk, it does have an effect on filaments and active regions on the surface. 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, following the filament through it’s structure toward you and away from you, allowing for enhanced visual and imaging capability for the observer as well as a research tool for the avid hobbyist. The pressure tuning system provides an order of magnitude more precision to the tuning of the desired features.Lunt 100mm Specifications: (single stacked)
