Hi guys,
I'm thinking about purchasing the Skywatcher 250mm Solar Filter (Filter cell + Baader Solar film) to use on my 10" GSO dob, but the following pic (link) shows no attachment screws.......... hopefully I can use Velcro to attaching it to the scope....
anyone else used this filter?
On the specs, it shows: Size 60 mm (Outer Diameter 275 mm) I'm not sure what the size 60mm is all about....
