Lunt LS100MT H-alpha 100 mm with B3400 blocking filter and R&P focuser – Ref. 0551424

Description

The Lunt LS100MT/B3400 R&P is a professional solar refractor designed for advanced observation of the chromosphere in H-alpha. The 100 mm triplet ED objective with FPL-53 glass offers outstanding chromatic correction.

The internal etalon is tuned via the Pressure-Tuner system, which adjusts the air pressure to provide a fully uniform solar image with no central obstruction.

The B3400 blocking filter is integrated into the 90° diagonal, mounted on a 2" Rack & Pinion focuser with 10:1 micro-reduction, ideal for large sensor imaging and demanding visual observation.

Its modular design allows night-time conversion using an optional kit (ref. 0551430). The scope includes a hard case, Vixen dovetail, tube rings with handle, solar finder and manual.
