Hello, Currently I am looking for some information on solar wedges, I have heard that they are quite safe and that they are very similar to each other, I have seen that there are Lunt, Baader and Lacerta, Altair ... as main brands, maybe there are others. I have read that Lacerta has a special characteristic, the angle in 56.6 degrees that the prism presents, will you notice a difference in the solar image in relation to those that present the prism at 90º? I would also like to ask you, apart from the ND3 filter, which filters are worth putting in the sun wedge? I have read that if a polarizer, that if a solar continuum, that if another of lower density neutral density ... in short, a whole mess for me that I have never had a solar wedge ..., I want it for visual observation! Ah ... I forgot, is it true that 1.25 "wedges are only valid for refractor telescopes up to 4"? and the 2 "ones for refractors up to 175mm? Thanks in advance for your valuable advice. Cheers, Tico.
