• For highest contrast even at strongest light pollution, minimizes star size, emphasizes finest nebula detail – indispensable under Bortle 9/8/7/(6) skies
• Reflex-Blocker™ hard coated and planeoptically polished – with sealed coating edges (Life-Coat™)
• Blackened edges all around, with filter-lead-side-indicator in the form of a telescope-sided black outer rim

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!

• 2" camera adapter for digital compact cameras (for eyepieces with diameters between 29 and 63mm )

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