Solar film on 8 inch SCT

Postby Mibmom » Fri Feb 26, 2016 12:56 pm

Hi Guys.
With the coming of the solar eclipse, I am going to get a Solar film to apply to my 8" SCT.
Question is should it cover the whole aperture or just a small amount of centre?
Thanks!

Definitely whole aperture. You risk blinding yourself and destroying the scope otherwise.

Hi geyes30,

Thanks for the reply.
I meant to cover the whole aperture with the solar film or only have a small aperture with the solar film and cover the rest with cardboard.
eg below:

Won't make much of a difference save for resolution (of sunspots), which will be rather minute.

Hi Mariner,
So I should just save the extra filter and use it for some of the other scopes?

Ahh... That makes more sense. I thought that might be what you meant, but figured the PSA was more important. I am deciding between these options myself, and have decided to just go with a smaller scope. More portable, saves on film. :D

Thanks Geyes30. I should have been clear in my description.
It is good to not assume anyone knows how dangerous it is to do solar viewing.

Bad idea.

You need to reread the requirements for a herschel wedge.
