Making a Sun Filter for the Starblast 4.5

To make the filter I used a sheet of Seymour Solar film, construction paper, wood glue, double sided tape and a strip of moleskin.

First step cut the construction paper into strips.


 I took two pieces and taped the together around the front of the scope to size the filter ring.  Then started gluing the remaining strips to the ring with the wood glue and let them dry over night.  
  After it was together I used sandpaper to smooth out the edges.
(One tip would be to size the filter ring a little big because after it was done it got a little tight around the scope.)


Next step was to trace out some rings on a thin sheet of cardboard.  
I used the filter ring as my guide for the outer edge then a roll of masking tape to trace the inside edge.



I cut them out with an Olfa knife and and glued one to the filter ring and let it dry over night.



After it was dry I put little pieces of double sided tape on both sides of the rings then turned the whole filter ring upside down on the Seymour film and using the Olfa cut the film to fit.



The top ring was then put on top of the filter and pressed down to make sure the double sided tape was stuck.


Just as a precaution to keep it all together I used a strip of moleskin around the edge.  




The filter is now done and ready for viewing!


The first views!  I tried to take a picture with my phone which was a little difficult to line up.  The view was a lot better through the eyepiece.  


There was a Sun spot in the lower right that was difficult to focus on with the phone so I zoomed in for a better view.


The Sun filter was pretty quick and easy to make and like I stated earlier the views of the Sun spot were much better than what the pictures show!
