Product information "LUNT LS50FHa/B1200d1 H-alpha solar filter"
50mm H-alpha solar filter system with B1200 blocking filter, for front mounting at telescopes with 1.25" focuser, and up to 1080mm focal length.
The LS50FHa H-alpha Etalon filter system with 50mm aperture (no central obstruction) for use on any refractor and many other telescopes. Because the LS50FHa has an estimated bandwidth of <0.75 Angstrom it is capable to providing high contrast views of both solar surface and edge detail (prominences).
The system includes the B1200 blocking filter, which is usable for telescopes up to 1080mm focal length. Larger blocking filters suitable for longer focal length are also optional available. The blocking filter is installed in a 90° star diagonal for 1.25" focuser. This diagonal is equipped with a reception for 1.25" eyepieces and a T2 camera connection.
Adding an additional available double-stack Etalon system will reduce the bandwidth to ~<0.55 Angstrom.

BRESSER Space Explorer 150/750 Telescope with EQ3 Mount
€499.00*
The BRESSER Space Explorer 150/750 Telescope with an EQ-3 Mount shows you the night sky in stunning detail. Go on a journey into distant worlds: Thanks to the combination of a large 150 mm aperture and a short 750 mm focal length, you can marvel at a vast array of celestial objects such as large nebula, open star clusters or the Andromeda galaxy. The powerful Newton reflector telescope is also great for observing our own solar system: with the 25-mm Plössl eyepiece, you can view the moon in 30x magnification. The premium parabolic primary mirror produces significantly sharper images and better contrasts than a comparable telescope with a simple spherical mirror. In addition, the telescope also has a large 55 mm secondary mirror that illuminates the field of view perfectly to create a bright image.
Portable design - with the 150/750 reflector telescope
Can't wait to get out of the house to view the Orion Nebula or the Pleiades? With this telescope, you can search for the perfect observation spot: thanks to the short focal length, the tube is short and easy to transport. In addition, the premium equatorial mount allows even beginners to set up the telescope in no time. Tracking is also very simple - you can compensate for the earth's movements manually so that your observed objects stay within the field of view. To ensure maximum viewing comfort, the focuser on this Newton reflector telescope is attached to the side of the tube. The aluminium tripod is height-adjustable and features an accessory tray so that you can keep all your important gear within reach. The 6x30 finder scope with reticle allows you to align the telescope with objects in the night sky. The reticle indicates the position at which your telescope is pointing. If you want to capture images of your nighttime discoveries, you can connect your smartphone to the telescope via the smartphone camera adapter.
