[QUOTE="Binastro, post: 3170776, member: 111403"] . Firstly, why do I get an advert for Bed bug removal just above this message box? Very strange. Anyway, Grando, I think that Baader planetarium eclipse specs may be pretty similar to the free ones. Maybe one is better at resisting scratches or less likely to have pinholes. Somebody else will have to advise. This morning, with a very clear transparent sky at 0850 UTC I got a good but slightly strange coloured view of the Sun. It looks orange, which is not unpleasant, using the sky at night free solar specs. It was high pressure 1038Hp. Just now in the Street I again got a good view, however the Sun looked a bit dimmer. I think that the reason was that looking out of the kitchen window the pupil size of my eyes was larger than when I was out in the Street in very bright sunlight. The free solar specs seem to be the correct shade. There were no sunspots visible today with protected unaided eyes. There are two close sunspots, which are nearing the limb of the Sun, as it rotates, but these are too small to be seen without a properly filtered telescope. I think that they may be too small even for binocular projection. I also viewed the Sun this morning with an H Alpha telescope. There was medium activity, some prominences not large, some filaments, and a few small sunspots. But the activity on the Sun changes constantly, and it is quite likely next week there may be some larger sunspots. For consideration of safety I will quote what is written on the inside right part of the free solar specs. ' SAFE FOR DIRECT SOLAR VIEWING. Maximum continuous viewing three minutes; intermittent viewing several hours. Do not use if lenses have scratches, pinholes or tears. Do not clean or disinfect. Do not use with other optical devices. Do not move around when wearing glasses. Do not wear if you have an eye disease or after eye surgery. This is not a Toy: use by children under adult supervision only. WARNING: NEVER LOOK AT THE SUN WITHOUT SPECIAL EYE PROTECTION. Use these glasses to protect your eyes from solar radiation any time you look directly at the Sun or its reflection, no matter how small a part of it is visible. On the left side of the free specs are the European standards specifications, which is good I was not aware that there are now official transmittance requirements, also maybe for Australia and New Zealand. These free specs are manufactured or at least supplied from America. One slight problem that I had was that although they stayed on easily without glasses, when I was wearing my distance glasses then I had to put the free solar specs just in front of my glasses, and although they did hold, they did not do this very well. So you may have to hold them with your fingers if you use your glasses with the free solar specs in front of them. This is to ensure that they don't fall off or slip so that you might accidentally view the Sun without protection. [/QUOTE]
