Scopium SF92 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 SF92 solar filter has a clear aperture of 92 mm and can be fitted to telescope tubes with an outer diameter of 84–110 mm from various manufacturers.
The securing screws feature plastic inserts, offering a dual benefit: they provide stable, vibration-free attachment while preventing scratches or damage to the outer surface of the 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 enters the objective lens, which is essential 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’s specifications and observing conditions allow it. The filter displays the Sun in a light yellow colour.
