Well, all I can tell you is I know what I saw through the guys scope. As I recall there was some blue-green as well but almost the whole thing looked red. This was the first time I'd looked through a big scope and it was my first star party before I got hooked on this hobby. I don't have any specialty filters so I can't say anything about them. Could I have "imagined" it? I was so awestruck when I saw it maybe so Outside of used anybody know the least expensive ones to get and where (outside of AM or course)?
