Greetings,

I have an old star explorer SE114900 telescope (lens aperture of 114mm, focal length 900mm).

Is it safe to use this to project the sun onto a sheet of card. Or am I likely to melt something (internal). I am not overly fussed what happens to the scope as it has a big brother now.

Are there any safety concerns outside of looking into the eyepiece and setting my retina on fire? Or the screen?

Any tips and pointers would be greatly appreciated.

I had a brief play with the idea today and was able to project a reasonable image, although i have not figured out how to get clear shots on a white background with the digital SLR. Although i was able to make a quick sketch.
