Baader 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

• 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,-)

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!
