Narrowband Bi-Colour imaging is a growing new trend in astrophotography, especially popular in light polluted areas, or for imaging in rural areas in moonlight.
The Altair 1.25" Solar Continuum filter Enhances sunspots, granulation, and fine photosphere detail. For use with Baader Solar Filter or Herschel Wedge.
The Altair 2" Solar Continuum filter Enhances sunspots, granulation, and fine photosphere detail. For use with Baader Solar Filter or Herschel Wedge.
Altair Starwave v3 0.8x Reduces exposure time and gives a larger, flatter field with various refractors.
Antares Secondary Elliptical Mirrors 2.6" 1/30 wave
Clear view, clear decision: Choose Antares and experience astronomical observations in a new dimension. Our secondary mirrors allow you to capture the beauty of the cosmos with razor-sharp clarity.
Choice of different sizes and wavefront errors (Wave PV):
Note: The minimum requirement for diffraction limited optics is L/4
