Tom Jonard's 4-1/4" f/10.5 telescope

Here's my long 4" setup for solar viewing via projection during the Mercury transit of  November 15, 1999.  This is a 60's vintage Edmund "Palomar Jr." that I've refurbished several times.  The tube (which is aluminum), primary and cell, secondary and mount and focuser are original.  The 6X finder is a replacement.  The 0X finder is a modified Tasco gun sight.  The rings holding the OTA are over-sized to allow tube rotation.  The mount is a standard Polaris mount with Right Ascension drive.  The projection system is my own.
