I've come up W/ my own design for a two mirror telescope, and I'm curious if it's any good. Basicly, It's like a newtonian, exept that the diagonal is full apeture w/ a small central hole. Light enters through the side, and is focused through this hole into th eyepeice behind it. I think this would allow for a very "fast" system yet w/ a small obstruction. It could be dobsonoian mounted because the focuser is on top. Some of the drawbacks I could think of are: Weight of the larger diagonal; Coma from the fast paraboloid; baffling; and mounting the focuser on a tilted surface. I've also come up w/ some partial solutions. E-mail me if you're intrested in disscussing this idea, or have the knowledge I lack of optics, and telescope making. DanRubright@USA.net
