FAQ - Frequently Asked Questions

Why do I see everything upside down and mirrored in the finder?

That is normal. Finder scopes are only used to make objects easy to locate. The image orientation does not matter for observation.

What is the difference between an alt-azimuth mount and an equatorial mount?

Alt-azimuth: easy to use, moves horizontally and vertically
Equatorial: enables precise tracking of objects with only one axis – ideal for high magnifications and astrophotography

What minimum apertures do I need for certain objects?

Moon: from 30 mm
Planets: from 100 mm
Deep sky: from 150 mm

Product information "LUNT LS100FHa/B3400 H-alpha solar filter"

100mm H-alpha solar filter system with B3400 blocking filter, for front mounting at telescopes with 2" focuser, and up to 3060mm focal length.

The LS100FHa H-alpha Etalon filter system with 100mm aperture for use on any refractor and many other telescopes. Because the LS100FHa has an estimated bandwidth of <0.7 Angstrom it is capable to providing high contrast views of both solar surface and edge detail (prominences).
The system includes the B3400 blocking filter, which is usable for telescopes up to 3060mm focal length. The blocking filter is installed in a straight extension tube for 2" focuser. This extension tube is equipped with a reception for 2" eyepieces and a adapter for 1.25" eyepieces.

Adding an additional available double-stack Etalon system will reduce the bandwidth to ~<0.5 Angstrom.
