DayStar ION 0.4 H-Alpha Solar Filter - DiscontinuedWhat's new in the solar h-alpha observing world? It's the ION 0.4 H-Alpha Solar Filter and the the DayStar ION series.
The DayStar ION series is a new breed of filter designed for rear mounting on your refractor, Schmidt-Cassegrain or Maksutov telescope! It's easy to use single knob design moves in 0.1 degree increments, while an LED indicator light let's you know when the filter is on-band or setting to temperature.
Astrophotographers will love the new ION. Dual MagLev (Magnetic Levitation) fans for increased cooling capacity have no visually detectable vibration - and that means crisp, clean images with far less trouble. It also accepts standard Quantum plates, providing mounting to T-thread, SCT thread, or 2-inch drawtube, for use with eyepieces or cameras.
The DayStar ION was created to replace the T-Scanner and according to DayStar employees, "It is so much easier to use than the T-Scanner and is the most user friendly filter we have made to date!"
