[QUOTE="Felisek, post: 427238, member: 23887"] Old good days of floppy disks! The disk inside was a perfect solar filter for viewing eclipses. I even made a filter to put on top of my MTO telescope using a 5" floppy, if I remember correctly (it was in 1999!). I used cardboard and parcel tape. The floppy disk did not cover the entire aperture of the mirror lens, but it was good enough to take a few shots. I must have filled the central hole in the disk somehow, though I don't remember how I did it. Nowadays, you can [URL="http://www.amazon.co.uk/Solar-Filter-Telescopes-Binoculars-Cameras/dp/B00DS7IFQS"]buy solar filter sheet[/URL]. I might be tempted to get one. [/QUOTE]
