I recently installed the telescope permanently in my observatory and use it know with Mel Bartel's AltAz system. The modifications of the mount, necessary for use as a computerized telescope, you can find on mycomputerized Dob page . I also designed a PCB for the electronics of the system. For free download of the artwork and diagrams please visit myPCB page .
To have easy access to the mirror without having to open the complete tube and to allow faster cooling of the mirror, I installed a mirror access and ventilation door in the tube. The door turned out to be very practical for cleaning the mirror, too. Since I clean the mirror with Collodion, I do not have to remove it from the telescope.
The cut-out from the front baffle serves as counterweight that can easily be fixed to the front or rear end of the tube. By adding small wood circles, the weight can be changed.
To have easy access to eyepieces and filters while observing, I added an eyepiece board to the mount. It can hold 7 eyepieces and 7 filters. As most of the telescope, it is made of plywood.
Also have a look at mySliding focuser design !
While in Richard Berry's book the tube is only baffled with 1 central baffle, I added three additional Baffles between the middle and the mirror to increase contrast.
