• Weight: 1070g

• 1¼" Double Stacked Baader Solar Continuum Filter. 8nm / CWL 540nm.
• Includes 1x AstroSolar^® Photo Film OD 3.8 20x29 cm. The filter includes two Baader Solar Continuum Filters in a single filter cell which have been stacked for even higher contrast.
• Enhances the contrast and reduces the effect of atmospheric turbulence.
• This filter must be used in conjunction with a Baader Herschel Wedge or Baader AstroSolar^® Safety Film 5.0 (not included) for solar observations otherwise equipment damage may occur. The included Baader AstroSolar^® Photo Film 3.8 must not be used for visual observation but only for solar photography (e.g. lucky imaging).

• Suitable for all UFC systems
• Closes the aperture of UFC and telescopes at the same time to create darks with CMOS Cameras

• M68 changer for Zeiss adapter system
• Hardened steel - no impressions in the mating surfaces of the dovetail may occur even with the greatest burden

• Complete packaging for The Original: Baader Planetarium (#2000000 , € 2450,-)
• Already 1x included with the planetarium

• Adapter with M43 x 0,75 male thread to T-2 (M42 x 0,75) male thread, e.g. for Takahashi instruments
• This connection ring allows to connect e.g. a binoviewer or a ClickLock^® eyepiece directly at the focuser with M43 x 0,75 female thread (e.g. Takahashi)
• Our M43x0.75 / T-2 (TAK)-Adapter includes a M34 inner thread to mount our T-2 Glasspath-Correctors to use with Binoviewers
• Optical path length only 0.8 mm
• To use T-2 parts on a M43i x1 female thread (meaning a M43 female thread with 1mm pitch per turn), we recommend our Baader M43a x 1 / T-2a Adapter (e.g. for Vixen) (#1508037 , € 33,-)

• Enables the use of up to three instruments at the focal plane of a telescope.
• Designed, manufactured and assembled in Germany
• The light passes through the IMP either undisturbed to the rear port (port 1 with 85 mm free diameter), or it can be deflected to the left or right (ports 2 and 3 with 67 mm free diameter) via two automated 40 x 40 mm mirrors with BBHS coating.
• Can be controlled by a keypad or remotely via a webinterface.

• made of V2A stainless steel
• Ø 140x30mm, bore Ø 28,7mm
• 3 kg

• Nosepiece 2" to M54a, ultra-hard with Safety-Kerfs
• Focus-sided M54 male thread
• Telescope-sided 2" barrel with 2" filter thread (M48)
• Insert depth 23 mm, optical path length 4,3mm

• Baader M55a / M68a (Zeiss) adapter for all Baader 2" mirror and prism star diagonals, for direct connection to the M68 Zeiss thread
• With this adapter you can convert your Baader 2" Diagonal on both sides to M68 thread connection. To do so, remove the 2" nosepiece or ClickLock^® and the M55/2"/S58 ring from the housing of the star diagonal and screw in the M55/M68 Adaper instead.
• To remove the black 2 "SC / S58 threaded ring from the housing and expose the M55 thread, you will need the Adjustable pin type face wrench ø 2mm (#2450062 , € 17,-)
• Suitable for the following 2" mirrors/prisms (already included in the delivery of Baader 2" ClickLock Diagonal Mirror M68 thread (Zeiss) (#2956100Z , € 309,-) ):
  • Baader 2" ClickLock Diagonal Mirror (#2956100 , € 296,-)
  • Baader 2" BBHS ® Mirror Diagonal with 2" ClickLock Clamp (#2456115 , € 479,-)
  • Baader 2" BBHS ® Prism Star Diagonal Prism with 2" ClickLock Clamp (#2456117 , € 505,-)

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!
