Scopium SF132 solar filter in cell enables safe solar observation with telescopes of the appropriate size. One of the product's key advantages is its robust aluminium filter frame, providing a durable and reliable solution even with regular use.
The Scopium SF132 solar filter has a clear aperture of 132 mm and can be fitted to telescope optical tubes with an outer diameter of 124–150 mm from various manufacturers.
The retaining screws feature plastic inserts, offering a dual benefit: they ensure stable, vibration-free attachment while preventing scratches or damage to the outer surface of the optical tube.
A further advantage is that the filter can be replaced if damaged, making the system easier to maintain and extending its service life compared to fixed-design alternatives.
Thanks to front-mounted filtration, solar radiation is significantly reduced before it reaches the objective lens, which is an essential requirement for safe solar observation. When properly secured, the solar filter film is suitable for observing the solar disc, sunspots and other photospheric details, provided that the telescope specifications and observing conditions allow it. The filter displays the Sun in a pale yellow colour.
