Product Info for Coronado SolarMax II 40mm Telescope Double Stacking Filter with Richview Turning System

Coronado Double Stacking Filters for SolarMax II Telescopes feature a narrowband element front unit filter and a T-Max de-tuning device. The Double Stack Filter by Coronado is useful for your solarscope as it will give you a better view of an image. These Coronado Double Stack Filters will provide a higher contrast and greater surface detail of the sun through your Coronado Solarscope. The Double Stack Coronado Filter works by lowering the 0.7 Ã… (angstrom) bandwidth to 0.5 Ã…. This lower bandwidth will allow for spectacular images and surface features, such as prominences above the Sun's disc, which are not normally seen in the 0.7 Ã… bandwidth. The Solarmax II Double-Stacking Filter fits directly to the front of your Telescope Accessories with the use of Adapter Plates for Double Stacking Filters.image

Features of Coronado Solar Max 2 Double Stack Filter:

  • RichView tuning system allows unprecedented high contrast views thanks to direct tuning of the primary filter etalon
  • Reduces normal bandwidth of SolarMax II Telescopes from .7A to .5A for better surface detail of active regions
  • Must be combined with a primary SolarMax II filter and blocking filter or complete Coronado SolarMax II telescope
