Sun Filter for 150mm Newton Telescopes

thingiverse

I created a Sun Filter that should fit most 150mm Reflector Telescopes. I´m using it with my SkyWatcher 150/750 Explorer -Get yourself a filterfoil and cut it out with 140mm diameter. -Print out the two parts -Put the foil in the outer ring and push the inner ring in gently. Pay attention to not touch the foil with your fingers as it might damage it -Maybe add some layers of tape around the outer ring (as shown in the pictures) to garantee a tight fitting (The Filter should not fall out while looking at the sun this is very DANGEROUS!) -Enjoy the view;) !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Never look directly at the sun especially through a telescope without a FIlter. Only buy a certified sunfilter foil! Cover your finder scope while pointing at the sun. Risk of blindness Don´t use it if it doesn´t fit perfectly to your Telescope. Use it at own risk. !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
