The LS100 H-alpha system with a diameter of 100 mm for use with any refracting telescopes and most other telescopes. The system includes blocking filters, whereby the B1800 blocking filter is designed for telescopes with a focal length of up to 1620 mm. The even larger blocking filter is designed for an even greater focal length.
Since the LS100 has a bandwidth of approx. <0.7 Angstrom, it is able to offer high contrast, both for observations of the sun's surface and for details at the edge. By adding an optionally available double-stack etalon system, the bandwidth can be reduced to approx. <0.5 Angstrom (depending on the telescope used). This results in higher resolution for observation or photography.
Scope of delivery:
- Main filter
- Blocking filter (for 2" focusers)
- carrying case
