About this product

Model:  lunt_80mm_ha_b1800_ft_pt
Part Number:  0551310

Complete H-alpha solar telescope with 80mm aperture, <0.7 Angstrom bandwidth, advanced air-pressure tuning system, B1800 blocking-filter and Feather-Touch focuser. 

The LS80THa/B1800FTPT is a complete telescope for observing the sun in H-alpha. A precision aligned ED refractor with 80mm aperture (no central obstruction) and 560mm focal length.

An internal Etalon with advanced air-pressure tuning system provides <0.7 Angstrom bandwidth. This 'Pressure Tuner' system is more accurate Etalon adjustments than other systems for always optimal performance. The Etalon is installed safely inside the telescope-tube. 

Fitted with the highly regarded 2" Starlight-Instruments Feather-Touch focuser with 1.5" travel and 10:1 reduction. 

The large B1800 blocking-filter provides wonderfully detailed views. It also has less vignetting so is an excellent choice for imaging.  The star diagonal, in which the blocking filter is installed, is equipped as standard for 1.25" eyepieces and has a T2 camera connection.

An additional DSII double-stack system (article no. 0551390) is also available that provides an even narrower <0.5 Angstrom bandwidth (reducing the bandwidth reveals more detail on the solar surface).
