not coming into focus
Posted By jerry palmer
i am new to the refracter scene.i just bought a genesis non sdf, i put my newer 2 inch televue diagonal in it and a 12mm type 2 nagler. when i rack the focuser out all the way stars do not come into focus. it needs about another quarter inch of travel to come into clear focus.so i have been moving the diagonal itself back to gain focus,is this right??i currently own a sct with no problems with this diagonal. so is the genesis at fault???
