| In order to observer and take pictures of the sun it is an
absolute MUST that you use a solar filter which
blocks 99.9% of the sun's energy from entering the telescope. You
can purchase a filter on line or you can build your own using
Baader solar film. This can be purchased in various sizes ranging from
A4 sheets to rolls. Various online sources are are available. (

I
opted to build my own filter using a 6" embroidery hoop which I
absconded with from my wife's sewing supplies. These hoops come in
various sizes. You have to check out a sewing supply store
to see if they have something that will fit your scope
Fortunately the outside of the scope tube is 5.5" allowing me
to put .25" rubber foam weather seal tape around the inside of the
ring providing a snug fit around the outside of the tube.
To compete the filter I sandwiched the filter
foil between the inner
and outer ring and tightened the thumb screw. Just to make sure
that the filter stayed in place you can applied some tape around the
outer ring
Obviously, this worked for me because the size of the tube matched the
rings.
If you want to try making your own solar filter you
will have to hunt around for hoops to match you telescopes
out side diameter.
