The Scopium SF192 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 cell, offering a durable and reliable solution even with regular use.
The Scopium SF192 solar filter has a clear aperture of 192 mm and can be fitted to telescope tubes with an outer diameter of 184–210 mm from various manufacturers.
The fastening 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 telescope 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 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, as well as examining sunspots and other photospheric details, provided that the telescope specifications and observing conditions allow it. The filter presents the Sun in a pale yellow colour.
