200mm AstroSolar OD 5.0 Filter

The Baader Planetarium 200mm AstroSolar OD 5.0 Filter is designed for visual solar observation and imaging. It uses AstroSolar Safety Film to deliver high-resolution views of the sun while protecting eyes and equipment. The filter fits telescopes with specific outer and inner diameter ranges. It is intended for astronomers who require a secure, stress-free mounted solar filter.

Multiple safety straps and glue pads

The filter includes multiple safety straps and glue pads that secure the unit to the telescope tube. This mounting system prevents accidental dislodgement during observation sessions. Adjustable clamping ranges of 230-260mm and 220-250mm outer, plus 250-280mm and 260-290mm inner, accommodate various telescope models using the supplied bolts. The hardware ensures a firm attachment without stretching the film.

Stress-free film mounting

The AstroSolar film is mounted entirely stress-free to preserve diffraction-limited optical quality and avoid the ripples that degrade high-magnification performance. A clear white IR-rejecting front ring with reinforcing raised edges adds structural rigidity while reflecting infrared energy. This construction maintains the film's precise optical flatness for detailed solar imaging and visual use.

Questions about this item

How often should the AstroSolar Safety Film OD 5.0 be inspected or replaced?

The film is mounted stress‑free in a cell and quality‑inspected; with careful handling and storage it remains optically stable for many years of visual and imaging use.

What clamping range should I check first when fitting the filter to my 200 mm telescope?

Verify the outer clamping range of 220–250 mm or 230–260 mm against your tube diameter; the correct range prevents stress on the film and keeps the safety straps secure.

Does the OD 5.0 film heat up noticeably during all‑day solar imaging sessions?

The white IR‑rejecting front ring with raised edges reflects infrared energy, so the filter itself stays cool even during extended visual or photographic sessions.
