Coronado SolarMax II 90 Telescope with BF30 Blocking Filter with RichView Tuning, SMT90-30
Coronado by Meade SolarMax II 90mm Solar Telescope with RichView system. Includes Blocking Filter. The incredible Coronado SolarMax 90 series telescopes are the largest H-alpha (Ha) telescope ever to be mass-produced and are now available with the patented RichView tuning system. This awesome solar observatory features a sub .7 angstrom bandpass.
Used around the world by serious solar enthusiasts and professional research facilities alike for observation of surface detail and prominences on the Sun in hydrogen-alpha (Ha) light. Powerful but very portable, this high resolution Solar Telescope offers dedicated visual observation of the Sun as well as high quality imaging.
The stunning bright red views through a Coronado Ha telescope display astounding surface and limb detail especially when the Sun is in an active phase. The sun is now heading for Solar Maximum, when activity will be at it's best. Don't miss out!!
This very high quality 90mm personal solar observatory features an 800mm focal length, f/8.8 focal ratio. Includes mounting rings, Sol Ranger finder scope, Cemax eyepieces, and travel case.
The Blocking Filter is the second element in any Coronado H-Alpha system, it is just as crucial to your safety and the system's performance as the front element. Use the following guidelines for selecting which Blocking Filter you need based on the focal length of the telescope being used. If you are switching to a longer focal length telescope your SolarMax system you can purchase blocking filters separately. There is no advantage for visual use in using a larger blocking filter than required based on the focal length; however, based on customer feedback, we understand that for imaging with telescopes under 500mm fl, the BF10 is easier to use than the BF5. The Blocking Filter is not a stand alone filter. It is an integral part of the Coronado design and cannot be used without a SolarMax series filter on the front of the optical system.
BF30 For Focal Lengths <3000mm - Image Size: 27.2mm
The new Meade Coronado II represents a breakthrough in solar observing with the new and revolutionary new RichView tuning assembly. This patented system allows direct tuning of the primary filter etalon. No other commercially available Ha telescope can provide the tuning range and accuracy of the SolarMax II. Now you can tune for the highest contrast views of active regions, flares, filaments, and other surface detail, or quickly and easily re-tune for prominences on the solar limb.
