Baader Planetarium

• Baader H-alpha Ultra-Narrowband Filter – Premium Grade
• 3.5 nm FWHM (to harmonize the exposure time with O-III / S-II), recommended for optical systems from > f/3.4
• For highest contrast even at strongest light pollution, minimizes star size, emphasizes finest nebula detail – indispensable under Bortle 9/8/7/(6) skies
• Reflex-Blocker™ hard coated and planeoptically polished – with sealed coating edges (Life-Coat™)
• Blackened edges all around, with filter-lead-side-indicator in the form of a telescope-sided black outer rim
• Optimized for modern CMOS cameras, but likewise excellent for CCD camera technologies

We explicitly warn against observing the sun with a DeepSky 3.5 nm (equivalent to 35 Ångstroem) H-alpha narrowband filter, specialized solar chromosphere and prominence filters from SolarSpectrum start at 0.8 Ångstroem. Photographic experiments with a camera are theoretically possible, but by no means observe the sun with naked eyes – you endanger your eyesight!

• Baader levelling flanges are used to adjust the unevenness of the foundation or the concrete pillar as well as other deviations of the substructure from the perfect north-south alignment. They adjust these imperfections as close as possible to the mount, very precisely and steady, without reducing the stability of the pillar
• suitable as a pillar adapter flange to the
• Top plate precision milled flat and threaded to fit the base plate.
• Overall height: 100 mm

• Input voltage 220/230 volts, output voltage 25 volts / 10.5 A factory setting
• Why 25V? The control box of 10 Micron mounts can work with 24V up to a maximum of 27V. Since 24V power supplies can occasionally drop below 24V at high loads and low temperatures - which can lead to the failure of the control computer - the power supplies for GM 2000 HPS, GM 3000 HPS and GM 4000 HPS are therefore preset to 25V. This value has proven itself over the years.
