Using A Solar Eclipse Glass as a Filter?

Hello SGL,

 

I've been thinking of using a solar eclipse glass a filter. I'm quite new to astronomy, I currently own a very poor 2" telescope ( My New Telescope should arrive this week, ordered a 3" reflector). And since I live in a region with more cloudy days than bright ones, the sun always appears as a target in the sky, because it's always there (duh) and I've been thinking instead of projecting and burning my material, why not use solar eclipse glasses as filters?

Like using that small hole in the anti-dust protection(reflector telescopes) to place the glasses...

 

Would it possible? If yes, should it give a good image?

Firstly welcome to SGL - And second - Be very careful when observing the Sun.  ONE mistake and you will bind yourself. You will not get a second chance.

I would suggest waiting for your 3" refractor to arrive and then buying either a ready made solar filter for it   http://www.firstlightoptics.com/solar-filters/astrozap-baader-solar-filter.html  (you should find a supplier in switzerland hopefully) or a sheet of Baader solar film and making yourself a proper filter holder.  The only skills you need are "scissors and glue" DIY ability.  http://www.baader-planetarium.com/sofifolie/bauanleitung-objektivfilter-en.pdf  will show you how to make a holder.

With that in place you will see sunspots (if there are any) and the bright faculae on the surface.

Thanks! It seems like the safest way anyways

With the Baader ND5 film on the incoming end of the scope, views of surface detail can be enhanced with a green visual filter at the eyepiece if you have one. The Baader Solar Continuum Filter allows only a small part of the green spectrum through, but enhances views of the faculae and sun spots. The green filter isn't quite as good as the Sol Cont filter, but will improve views compared to having none.

I did this imaging test with a Luminance, Red, Green and Blue filter. With identical processing, the green light image gives by far the clearest view. The Sun will of course appear green in the eyepiece, but it should enhance views.
