Manual: SolarSpectrum H-alpha-Filter and Baader Planetarium Telecentric Systems
Example Adaptations
On the following pages we will show you some configuration examples, below a
complete setup using a refractor as an example, the other detailed examples using a
TriBand Schmidt Cassegrain (f/10) with integrated energy protection filter, to which the
telecentric is screwed via the SC thread. The examples refer to the Research Grade
TZ3 with 250 mm working distance and may have to be adapted to the working dis-
tance of your telecentric.
The examples are guiding values that work because of the parallel beam path of the
telecentrics – in practice it is not necessary to keep the calculated distances exactly to
the millimetre to get good results. Since the examples do not take into account the dif-
ferent optical lengths of the various H-alpha filters, you can determine exact distances
using the method described on page 28.
For SolarSpectrum filters, the red side always faces towards the observer, while the
silver side faces towards the telescope.
SolarSpectrum H-alpha-Filter example setup – complete system
The following image shows a fully equipped refractor telescope. The Dielectric Energy
Rejection Filter is instaled together with the variable diaphragm in front of the lens, the
telecentric system is inside of the M68 tele-Compendium.
The solar shade places the eyepiece into the shadow, which makes a better cont-
rast possible when looking in the eyepiece. The VarioFinder can be equipped with the
65 mm AstroSolar Spotting Scope Filter (ASSF)
