5-inch f8.1 fluorite refractor (2.7-inch focusing tube) complete with f5.9 focal reducer, 1.25-inch extension tubes, 2-inch ocular adaptor, 1.25-inch star diagonal and camera angle adjuster plus foam-lined wooden storage/transporting box.
Price $4800 plus delivery. (Note that the total new replacement cost for a TOA-130 which has replaced the FS-128 is about $9800.)
Why am I selling this great telescope? Because when the FS-128 was designed in the 1990s, Takahashi considered it unnecessary to provide a flattener for the film and smallish CCDs then in use. I am now using an STL 11k CCD camera with a 36 x 24mm chip and a flattener is needed to achieve round stars at the edges of the large field. (Stars are round over the complete field of a 22 x 15mm DSLR chip.) See aaq.org.au/member services/member galleries/max kilmister for some of my images taken with this telescope.

If you get the 4 inch focuser (from Texas Nautical) (US$895) you can use the FS152 flattener which comes up on Astromart every now and then (US$695) and you should get round stars to the corner with an FS128. I had an FS152 and did that and it had round stars to the corner with an STL11.
