Product Info

Manufacturer Description

The LS50THa from Lunt Solar Systems is a 50mm, unobstructed, pressure-tuned, dedicated Hydrogen-alpha telescope with a bandpass of <0.75 A.

The excitement of viewing our Star through a dedicated solar telescope is sure to provide many many hours of visual enjoyment and educational insights. This package is fully upgradeable at any time without ever having to go back to the factory. As the Sun becomes increasingly more active, you will appreciate that the instrument can grow right along with it.

The Lunt LS50THa Solar Telescope, complete with a Pressure Tuner,  provides the basic essentials perfect for a first time introduction to solar observing, while also including the newest technology for fine tuning, allowing basic research of the Sun’s disk and some surface details.

True Doppler Tuning (Pressure Tuning) allows for a shift into and away from the user, adding a 3D-like component to the viewing experience. While it has minimal effect on proms due to their being 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.

LS50THa Package Features:

  • A Narrow Band Hydrogen-alpha Dedicated System
  • A refractor-based system with a 50 mm front objective
  • An internal Etalon with a pressure tuner allows for <0.75 Angstrom bandpass

      Comments:

      Delivery to Australia was surprisingly fast, without any problems, well packaged and have used this scope more often than all the times with my usual night scope. Extremely happy that I choose Agena AstroProducts.

      4.0 Nice Ha Scope at a Reasonable Price-Poing

      Pros:

      Compact,Quality Lenses,Accurate,Lightweight,Strong Construction

      Cons:

      Needs A Standard Focuser

      Comments:

      This is my first Ha scope. Lunt has come up with a good combination of quality and price that is sure to invite many into the world of Hydrogen-alpha solar viewing.

      The build is extraordinary and the finish needs to be seen to be believed.

      One drawback is that it only has a helical focuser which makes solar photography a bit more difficult... thus the four star rating. I realize that a crayford style focuser would raise the price to possibly be prohibitive to the newcomer though.

      Note that, unlike others in the Lunt line, this scope doesn't come with a solar finder or a 4" dovetail. Make sure you order both with your new scope. I found the Sol-Searcher finder to be extraordinary. (Manish has 'em both.)

      The scope is a little bit "tail heavy", and since it only accommodates a 4" dovetail, there isn't enough travel to move it forward enough for perfect balance. However, the slight imbalance does not affect the drive motor on my CG-4 mount.

      (I think if one had the "double-stack" module on the front, it would be easily balanced.)

      As usual, Manish and his staff delivered everything rapidly and well packaged. They never fail.:)
