Delivered without blocking filter, use for H-Alpha sun observation only possible with additional blocking filter!This telescope is supplied without blocking filter. We offer a wide range of additionally available blocking filters in different sizes, either mounted in a 90° star-diagonal housing or in a straight extension tube. These are all usable with this telescope.ATTENTION: Without such an additional blocking filter you cannot use this telescope for H-alpha solar observation!Solar observing in H-alpha:The LS60MT is a telescope for observing the sun in H-alpha light, with 60mm free aperture (no central obstruction) and 420mm focal length. The H-alpha wavelength is the most impressive way to observe the sun, showing protuberances at the sun's edge, filaments and flares on the surface, and much more. An internal Etalon filter achieves a bandwidth of <0.7 Angstrom with the innovative air pressure tuning system Pressure-Tuner. Tuning is done by slightly changing the air pressure in a pressure chamber inside the telescope. This changes the refractive index of the air, making it easy to tune to the H-alpha line. The pressure tuner guarantees a homogeneous image, without central obstruction, and a permanently protected Etalon without erosion. A set of collimating lenses installed in the telescope ensures best performance.Fine adjustment is achieved with a solid 2 inch Rack&Pinion focuser with 10:1 reduction.This version of the LS60MT is delivered without blocking filter. Therefore an additional blocking filter is required to use the telescope for solar observation in the H-alpha wavelength.

The philosophy behind the Nebula GoTo system is to provide the user with a control system independent of a normal PC, which can be remotely controlled in all its functions via a smart device such as a mobile phone or tablet. However, this does not exclude the traditional use of computers of all types and brands, which can be connected to the system either wired or wirelessly. The BRESSER Nebula GoTo System Controller is a Raspberry Pi 4 microcomputer, which allows complete control of the setup (mount, camera, etc.) without the need for any other external device. The BRESSER Nebula GoTo system is already equipped with all Linux-based applications necessary for performing all astrophotographic functions.The existing INDI environment allows the control of almost all devices (cameras, filter wheels, rotators, including observatory domes), necessary for conducting local or remote astrophotography sessions. The system also offers high flexibility for users who prefer to use traditional computer client applications such as Cart du Ciel (Star Chart), TheSkyX, SkySafari, Stellarium, and other planetarium programs as well as SGP, Nina, CCD Ciel, and other astrophotography tools. This complete compatibility is ensured through the adoption of the Alpaca communication protocol, which allows the use of traditional ASCOM platform drivers for native INDI devices. State-of-the-art mount construction The BRESSER Nebula mounts are CNC-manufactured from stainless steel and aluminum. The simple and functional design is thanks to a renowned Italian mount manufacturer, who has designed and now also manufactures these fine BRESSER products 100%. So, look forward to a stable yet easily transportable mount, which despite its light weight of only 16 kg (including tripod) allows a high load capacity of up to 25 kg. Visual Observation For visual observation and direct use, control the mount with the hand control box included in the package. Alternatively, connect the Nebula 6 via WLAN directly to your smartphone or tablet and use the virtual hand control box. Of course, all adjustment parameters can also be adjusted via the web application. The user interface is deliberately simple and clear to ensure intuitive operation. Astrophotography Here, the Nebula mount shows its full strength. Whether mobile or stationary, remote capability is crucial. Connect your laptop or PC either via WLAN or with an Ethernet cable (recommended for faster data transfer) directly to the Raspberry-Pi control unit of the mount. Then use the pre-installed software Kstars/EKOS to control the mount and all external devices such as cameras, motor focus, filter wheel, etc. Alternatively, you can also directly control the unit with your own software. Applications such as Cart du Ciel (Star Chart), TheSkyX, SkySafari, Stellarium, and other planetarium programs as well as SGP, Nina, CCD Ciel, and other astrophotography tools can be used without any issues. 2-in-1 Mount with EQ and AZ Mode If required, the Nebula can be switched from the equatorial mode to the azimuthal mode. This is particularly advantageous for observing nature or tracking satellites. Thus, the mount can be used for various applications and is not limited to astronomy only. Attachment of up to two optics Would you like to adapt multiple optics? No problem. Simply use the option to replace the counterweight bar with another telescope. Use the second optic simply as a counterweight to the main telescope. Set the Nebula 6 to azimuthal mode, remove the counterweight bar, and screw on an extension adapter with a suitable second telescope clamp directly to the mount.
