While observing the celestial wonders, the 240mm AstroSolar Telescope Filter from Baader Planetarium ensures you experience the highest quality images. This filter, designed for astrophotography, is crafted with the renowned AstroSolar Safety Film OD 5.0, which has been the choice of astronomy enthusiasts for over 15 years. Unlike many ready-made filters, the Baader AstroSolar Filter is designed to maintain the true optical quality of the diffraction-limited AstroSolar Safety Film. It is mounted stress-free, ensuring it performs like a high precision plane optical window, which is essential for high magnification work. The filter is housed in a clear white IR-rejecting front ring with reinforcing raised edges. This design protects the solar filter material from contact with any sharp metal edge, ensuring its durability. The filter can be easily mounted and adjusted to fit a wide variety of mechanical tube diameters, thanks to its non-rotating sliding fasteners made from aluminum. For user convenience, the filter features an index scale beside each adjustment slot, allowing for fast and repeatable adjustment of the filter cell onto different telescope tubes. It also includes three security straps to ensure a secure fit in front of the telescope under any circumstances, such as a gust of wind. The AstroSolar Telescope Filter is safe for solar observation and photography with all high-end telescopes and extreme tele-lenses. It is suitable for the highest magnifications and detailed observation of individual sunspots. The temperature-compensated cell enables the AstroSolar filter material to retain its excellent optical quality at any temperature, from -30Deg C to +50Deg C. In the box, you'll find the ASTF Filter with two sets of centering bolts in 38mm length, three safety straps with glue-pads, and three rubber plugs to cover the holes that are not used, along with mounting instructions. Experience the sun like never before with the 240mm AstroSolar Telescope Filter from Baader Planetarium.
