Please note: This telescope is made to customer specifications. Therefore special conditions apply for this telescope and online ordering is not possible. Please contact our customer service if you would like to order this telescope.
Complete H-alpha solar telescope with 300mm aperture and a bandwidth of <0.65 Angstroms. With Feather-Touch focuser, innovative air pressure tuning system and B3400 blocking filter.
A really giant telescope for observing the Sun in H-alpha wavelength, a precisely adjusted refractor with a free aperture of 300mm without central obstruction and 2128mm focal length. A internal Etalon filter with the innovative air pressure tuning system Pressure-Tuner achieve a bandwidth of <0.65 Angstroms. The Pressure-Tuner system ensures a homogeneous H-alpha image and optimal performance. The Etalon is safely installed inside the telescope. The air pressure tuning system is precisely controlled by an electronic pressure tuner controller.
Blocking Filter is the B3400. The B3400 is well suited for imaging the Sun. For visual observation we recommend an additional zenith mirror. The straight extension tube, in which the blocking filter is installed, is equipped as standard with a 2" eyepiece holder and also with an adapter for 1.25". Focusing is done by the legendary Feather-Touch focuser from Starlight-Intruments with 10:1 reduction.
