LUNT B1800d2
Blocking-filter in 90° zenith mirror diagonal, for telescopes up to 1620mm focal length, and with 2 inch (50.8mm) focuser. 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 B1800d2 is installed in a 90° star-diagonal housing, for 2 inch (50.8mm) focuser on the telescope side, and with T2 thread and 1.25 inch (31.7mm) eyepiece connection on the eyepiece side. The B1800d2 can be used at LUNT H-alpha systems, if the used telescope has a 2 inch focuser and up to 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.
