Blocking-filter in straight extension tube, for telescopes up to 540mm / 1080mm / 1620mm focal length. Can only be used together with a LUNT H-alpha filter, or with a LUNT H-alpha telescope!

Lunt Solar Systems offers blocking-filters in different sizes, and alternatively in 90° star-diagonal housings or straight extension tubes. You can choose what blocking-filter you will use at your LUNT H-alpha Etalon system.

The blocking filter is installed in a straight extension tube, for 1.25 inch (31.7mm) and 2 inch (50.8mm) focuser on the telescope side, and with T2 thread and 1.25 inch eyepiece connection on the eyepiece side. The filters can be used at LUNT H-alpha systems, if the used telescope has up to 540mm / 1080mm / 1620mm focal length.

The blocking-filter can not be used without additional H-alpha filter system from Lunt Solar Systems! Blocking-filters are absolutely required for the safety and performance of H-alpha telescopes for solar observing. Lunt Solar Systems blocking-filters contain a unique filter system. We can only warranty safety or performance, if blocking-filter is paired with a H-alpha filter or H-alpha telescope of Lunt Solar Systems.
