EXPLORE SCIENTIFIC 2" H-Beta Nebula Filter

One of the most important obstacles for the exploration of the night sky is the brightening of the night sky by artificial lighting, such as streetlights. The night sky is not really dark in the vicinity of towns or cities, which reduces the visibility of objects beyond the solar system enormously. Depending on the type of celestial object, it is possible to increase the contrast dramatically by blocking the interfering artificial light. The EXPLORE SCIENTIFIC O-III filter uses a characteristic property of the so-called emmission nebulae. Those objects glow in special colors, the so-called emmission lines. Those emmission lines are linked to chemical elements - in this case oxygen. The EXPLORE SCIENTIFIC O-III nebula filter blocks all other colors (and thereby nearly all of the artificial light) and only the two emmission lines of the oxygen can pass the filter. The result is astonishing: suddenly, nebulae are visible in locations that were completely empty without using filters. In suburban skies, for example, the veil nebula NGC 6992 is almost invisible with a 200 mm telescope. By using this filter you can see the nebula and its structures without any difficulties. A must for every visual observer and for astrophotography.

The AP-SM mount is an enhancement of the AP mount. Unlike the AP mount, it has an RA motor and is equipped with the STARBOOK ONE controller. The AP mount provides a secure, stable support for your telescope. Thanks to the slip clutch mechanism, the mount can be adjusted quicky to the target object. There is a wide range of optional accessories. The ADVANCED POLARIS mount is ideal for both beginners and advanced observers who require a lightweight travel mount. STYLISH DESIGN The AP mount features an ultra-smooth finish without any projecting parts. Simply place your telescope on the mount and move it to the desired celestial object without having to loosen any clamps! QUICK POLAR ALIGNMENT The slip clutches allow you to adjust the telescope to your target object easily – no more searching for adjustment clamps in the dark! An optional polar meter is available, which enables you to locate the celestial pole when it is hidden by trees or buildings. OPTIONAL POLAR FINDER SCOPE The innovative polar finder scope provides a new way to polar align your telescope. Simply align the stars in the crosshair reticle with the same stars in the night sky. Polar alignment is achieved using 3 reference stars. The polar finder is illuminated to facilitate orientation and switches off automatically after 3 minutes to save battery power. POWER SUPPLY The RA and DEC motor modules are powered by four AA alkaline, Ni-MH or Ni-CD batteries. The RA motor module has a USB Micro-B port for an external power supply. A USB power pack or car charging cable can be used for longer observation sessions. STAR BOOK ONE CONTROLLER The STAR BOOK ONE is a multifunctional and intuitive controller that tracks in the RA and DC axis with a range of different speeds. The tracking options are designed for time-lapse cameras at a wide range of speeds, including sidereal, lunar and solar rates. The controller also offers many useful functions such as backlash compensation, autoguider port, PEC and a built-in red LED light. FEATURES R.A. Worm wheels: 58.4 mm Ø gear wheel with 140 teeth DEC.
