Our cyc is around 20+ feet high, and prolly a good fifty plus feet wide, and there is a need for a 'star field' effect for the upcoming show... Ive tried gobo's in our ERS's that Ive made with pie tins and a nail to punch through, either I get the hole to small, and it doesnt go through the metal, or to big and it looks like a friggan lighthouse or something, or I get it just about right, but many of the holes in the metal arent square shaped or round shaped anymore, and look like uh, odd geometric shapes, quite unlike stars... I'm going for a 'night sky' effect, using strips on my last electric batton with deep blue gels for the 'color' but I need to get a star effect across the whole cyc. Using ERS's and gobos Ive gotten select spots that SORT of work, but also, they're way to small... Ive only got four ERS's to cover the whole cyc. Im thinking of moving them even farther back away from the cyc but that means finding a way to make smaller holes in the gobos without mesisng up... Ive tried using a mirror ball also, while getting GREAT spread from just one instrument, and a rather nice intensity, the shapes produced by mirroring a par64 instument, or an ers just turn out to be blotches of light, circular and prolly close to a foot in diameter near the edges of the cyc. What can I do to make a better gobo, or some other way of projecting an image of the stars and a night sky?
