Best & low price

by Arunkumar Shaiwale, Verified Owner from India Written on April 6, 2018
A nice solar filter. Sun details show than must be this Filter Buy. A low price with shop. 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 A (angstrom) bandwidth to 0.5 A. 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 1. A bandwidth. The Solarmax II Double-Stacking Filter fits directly to the front of your solar telescope with the use of Adapter Plates for Double Stacking Filters.
