Scopium SF72 mounted solar filter enables safe solar observation with telescopes of the appropriate size. One of the product's key advantages is its robust aluminium filter frame, offering a durable and reliable solution even with regular use.
The Scopium SF72 solar filter has a clear aperture of 72 mm and can be fitted to telescope tubes from various manufacturers with an outer diameter of 64–90 mm.
The retaining screws feature plastic inserts, providing a dual benefit: the attachment remains secure and vibration-free while preventing scratches or damage to the outer surface of the tube.
Another 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, as well as examining sunspots and other photospheric details, provided that the telescope specifications and observing conditions allow it. The filter displays the Sun in a light yellow colour.
