Coronado Instruments has developed a series of Coronado Solar Telescope as a result of the often asked question, "What is the best telescope to use with a Coronado filter?" While almost all refractors and most reflecting telescopes can be used with a Coronado filter, no other telescope has been designed with all its optical aberrations and coatings optimised at H-Alpha. Most night-based astronomical telescopes, when used at H-alpha, will not have the image contrast exhibited by a Coronado SolarMax II 60 Double Stack H-Alpha Solar Telescope - Coronado Solar Telescopes, even the PST, have been designed with this one wavelength of light in mind and will increase contrast... giving you a darker background for viewing and imaging.

"Why buy a telescope that can only look at one object?" The Sun in H-Alpha is the most dynamic object you will ever see while pointing a telescope skywards. Constantly changing and never repeating itself, the Sun through a Coronado SolarMax II 60 Double Stack H-Alpha Solar Telescope will hold your attention for a lifetime. Coronado Instruments dedicated Coronado Solar Telescopes serve to enhance that view for you, your family, and friends. The telescopes provide an easy and portable set up that is always ready right out of the box. For those looking for more aperture we proudly present the SolarMax II 60 dedicated H-alpha telescope. Built to exacting standards the Coronado Solar Max II Double Stack 60''s provides the user a Coronado Solar Telescope with the same lightweight portability of our SolarMax II 40 but the extra aperture greatly increases the resolution of detail on the surface and on the limb. With over twice the surface area of the SolarMax II 40, the difference is obvious.

The Coronado SolarMax II 60 Double Stack H-Alpha Solar Telescope comes standard at Coronado Solar Telescope gives you the ability to adjust for Doppler shifted light. Bino-viewers and most imaging equipment will come to focus, sometimes with the use of a Barlow or OCS. The advantage of the extra aperture becomes clear each time you view.

This Coronado SolarMax II 60 Double Stack H-Alpha Solar Telescope is a handsome brass and black f/6.6 refractor with 400mm focal length and 60mm aperture. Its purpose is simple. The Coronado SolarMax 60 Coronado Solar Telescope SolarMax II 60 was intended to do much than just reveal sunspots... it was meant for studying prominences, flares, granulation and more. The achromatic doublet lens utilizes special multi-layer anti-reflection coatings on all air-glass surfaces to optimize anti-ghosting. This is an important feature when observing such a bright target as the Sun. Safety issues include hard vacuum-deposited. non-degenerating coatings. This means not only are you assured your vision is protected - but your investment as well. The Coronado SolarMax 60 Double Stack BF10, when properly cared for, will last a lifetime.

The dual etalons (one internal and one external) of the Coronado SolarMax II 60 Double Stack H-Alpha Solar Telescope are used to sharpen the filter'''s normal Coronado Solar Telescope barrel. This etalon combination provides the contrast benefits of double stacking, but offers it at a lower cost. By using factory-matched etalons, you are also added better performance than an additonal etalon added at a later time. Add even more definition by using Coronado Cemax Solar Telescope Eyepieces!

On the outside, the Coronado SolarMax II 60 H-Alpha Solar Telescope Coronado Solar Telescope you''ll find the RichView tuner which mechanically tilts the filter''s bandpass of the h-alpha line. This allows observance of Doppler-shifted solar activity, such as moving flares!

• Package includes Cemax eyepiece, hard travel case, Sol Ranger, clamshell mounting rings and five year warranty

   

   

• Provides an easy and portable set up that is always ready right out of the box

   

   

• Innovative RichView tuning system attached directly behind the etalon gives you the ability to adjust for Doppler shifted light

   

   

• Two-piece solar filter is formed from a full-aperture 60mm etalon positioned in front of the objective lens and a 10mm clear aperture blocking filter incorporated into the diagonal

   

   

• 10mm clear aperture blocking filter is perfectly matched to the focal length of the telescope to give full disk views of the Sun

   

   

• Manual 1.25" drawtube which extends for coarse focusing and secondary helical focusing ring around the drawtube is then used to provide the appropriate final fine focusing

   

   

• The dual etalons (one internal and one external) of the Coronado SolarMax 60 are used to sharpen the filter''s normal

   

   

• RichView tuner which mechanically tilts the filter''s bandpass of the h-alpha line
