Skywatcher 250mm Solar Filter for Reflector (Filter cell + Baader Solar film)

[Rogering1]

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..

Anyone else used this ?

On the specs, it shows: Size 60 mm (Outer Diameter 275 mm) I'm not sure what the size 60mm is all about....

It's likely that will just fit snug over the top of the tube. i have something similar for my 127 mak and it just fits tight around the rim. no real need for velcro etc, in fact you don't really want anything like that as something like a velcro patch will lift the seal of the rim and indirectly let light in, you want it as snug as possible
