After I completed my first telescope , I finished this telescope colorful again using vivid blue and silver colored cutting sheet .
Sealing the cutting sheet on the plastic tube is rather harder than on paper tube .
I surfer from air gaps between tube and the sheet .
I finally succeeded by using water spray like when you used it to add film on the car window.
Much brighter than my first 40 mm F10.5 telescope .
I want to try to make a mounting of metal like aluminum in the future with the help of my friend who works at the factory
I am planning to go to sea shore or mountains to enjoy seeing stars with my kids .
