Looking into the Sun with a solar filter

Показать описание

I designed and 3D printed this solar filter adapter for my 80mm binoculars so I can look into the sun. Sadly, the magnification is not that great and it looks like an orange, but we can see a few dark spots.

I used the Kingroon KP3S Pro and PETG filament for the printed part.

I got the Celestron SkyMaster Pro 20x80 hoping to use them for stargazing. Turns out more difficult than I thought beyond watching the Sun and Moon.

Bro could see the edge of the universe with those binoculars 💀

Maybe next time you could measure the radius of the circle and use a compass to mark the cut, that way no risk of damage

That is the reason 3d printing came to my life. To prepare components and adapters for my telescope!

Interesting thing about the sun filter material in this video is it starts out as a clear plastic film with sun filter material laminated on both sides, at least the good stuff does, don’t cheap out on this and get a single sided filter. Even though only one is adequate protection they do this in case there is a pin hole in the sun filter material. This type of filter is used to observe eclipse etc. There are purpose specific telescopes that will allow you to observe the turbulence at the surface of the sun.

Many years ago a telescope accessory manufacturer sold a eye peace that had a built in sun filter that replaced your eyepiece. Major problem, as the observer was looking at the sun the filter component in the eye piece started to heat up eventually shattered allowing the concentrated sun rays into the eye, blinding the observer.

Be very careful looking at the sun, any filter that does not filter the sun BEFORE it enters the telescope’s optical path can overheat the telescope and damage it as well as burn your eye out. There are purpose specific telescopes that can handle the heat as well as filter out dangerous light.
