• Sturdy swivel arm with clickstop for cameras up to 1.5 kg
• For afocal projection photography
• ClickStop Twist-Lock-Mechanism

Photography with larger cameras

The Microstage II is the universal solution for small compact cameras. Large cameras up to DSLR require a sturdier connection. In this PDF you find an overview of all adaptation options using the camera bayonet or lens thread

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!
