For sale is a ST-4, it is an older version (SN#900998) and shows some wear, but works perfectly.
I bought it used about 5 years ago and have used it only about 6 times (hense the sale).
All the mechanical relays were replaced recently and I have an additional never used set which is included.
The person I bought it from made a modification on the cooling fins to
accept a fan which helps the cooling of the CCD chip in warmer climates.
It comes with all cables including the cable the goes from the ST-4 to a G-11 mount, case and SBIG ST-4 Ver 2.08 floppy. Newer versions are available from SBIG on line. Also have original manuals and the original 1.25 nosepiece all in a fitted case.
The ST-4 also comes with a 120v ac adapter and a 12v adapter. Also it
has the Spectra flip mirror and focusing/centering eyepiece but no
I have some pictures (sorry in advance about the webam) if you need more.
I am asking $625.00 including shipping. CONUSA only.
Payment by postal money order, cashiers check, Paypal (add 3%) or personal check (add about 7 working day to clear).
