For Sale Status: Sold  Ad Category: Telescope-Refractor  Ad # 3409 Lunt Solar Scope LS230THa on Celestron CGX-L Mount,the only one of this caliber in Australia. LUNT SOLAR SYSTEMS - LS230THa - Pressure Tuned w/ B3400 Blocking Filter SOLAR TELESCOPE At 230mm F/7 the Lunt Solar LS230T/PT is by far the worldfs largest production Solar telescope beating out the previous record holder and now slightly smaller brother (LS152) by 80mm. The LS230THa/PT (pressure tuned) is a complete and dedicated Hydrogen-alpha Solar Telescope. A precision aligned refractor with a fully un-obstructed 230mm aperture. The 100% unobstructed system will perform to the highest level at both low and high magnifications. Utilizing advanced hi-contrast coatings and the new Doppler True Pressure Tuning system the user will be able to experience an un-paralleled level of visual and imaging performance. With an image size of almost 16mm at the eyepiece, the views through this instrument are truly breathtaking. Clear skies provide the feeling of seeing into every detail of our nearest Star. The LS230T is a limited production dedicated Hydrogen-alpha telescope with a bandpass of less than 0.65 Angstroms. Optical design by the well known Massimo Riccardi provides crisp, sharp features, while an unobstructed aperture allows for the highest level of contrast and resolution available in any Solar Telescope. The LS230T is a dedicated Hydrogen-alpha Solar telescope. The optics were specifically designed to be optimized at the 656nm wavelength. This includes a highly specified IR reflective coating that is applied to the surface of the front objective element to remove most of the heat from the system. Utilizing advanced hi-contrast coatings and the new Doppler True Pressure Tuning system the user will be able to experience an un-paralleled level of visual and imaging performance.
