|The Upper Tube Assembly for John's 8" F4. Here the Moonlite|
2-speed focuser and filter slide is installed.
(note the 1-foot ruler for scale)
|The filter slide "clamps" to the draw tube. Easy to install|
and easy to remove if necessary.
|Under construction is an OTA for John's 8" F4 short-focus|
primary. The OTA will sport a Losmandy dovetail plate for
mounting on a couple of different platforms.
John lives in Richmond, Virginia
|John's OTA will be "similiar" to this 12" F4 made last year.|
