 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.
