Its not long before the transit of Mercury on November 11th 2019 – see our recent blog to read more on this event. To observe or image this event one must be very careful as viewing the Sun without proper safety equipment can cause permanent blindness and/or damage to photographic equipment.
Baader Planetarium offer a range of Solar filters for viewing and imaging the Sun, and can be used for this Mercury transit event. One of the most popular, and inexpensive, Solar filters they offer is their AstroSolar sheets which are ~A4 in size (20x29cm).
A fun part of buying one of these AstroSolar sheets is being able to make your own filter holder for your telescope, camera lens or binoculars. Baader Planetarium have published some useful guides on how to make such a filter holder you may find useful.

As a final but important note it is important to review the safety aspects with Solar observation – you can read more here.
