Rear Hydrogen Alpha Filters

 

Our range of rear mounted solar filters allow you to convert just about any telescope to safely observe and image the Sun. These filters require you to add some form of ERF (Energy Rejection Filter) to the telescope. They are available in a range of bandpass options from 0.8A to 0.3A and even 0.2A to special order.
