Longer cell in the FD design.The new cell is bigger as is shown in the picture. You will have to cut some foam in the carrying case. If youorder the microfocuser more cutting is required.You have to use an extension to be able to focus with the new cell.The new microfocuserthe photo tripod setupThis is not necessarily a downside because I think that will help you to use binoviewers although I have to saythat I have not performed that test. It will also help when adding a focal reducer. I have used a Meade 0.63Xfocal reducer (with the SD) and it works but a lot of in focus travel is required.
OM-1 + 0.63 focal reducerRequired hardwareBefore getting into the imaging tests lets take a look at the physical arrangement inside the Megrez tube. Therehas been a lot of discussion about whether or not the light cone is obstructed by the baffles. From mymeasuring there is not a problem. I did not move the baffles back into the tube.Baffle trainHowever you have to verify your own telescope or ask William Optics. In my case the baffles are located 71mmform the lens side and that is OK. How the same baffle can work with a f/ 6.25 in a f/ 6.94 light cone I don’t know.I guess the effect is not that important if there is not an obstruction.
