I am selling my Spectrum 60mm for upgrade $450.00 since I now own a Solarmax 90mm. The upgrade is less then 6 months old with no damage. The PST body does not come with it thats why I have it greyed out. You will receive the 60MM F10 tube, the larger focusing knob, and the clam shell. This sells for $600 ($499 tube, $100 Clam Shell. Here is the link to the product:

I had to wait 2 months for the upgrade + send in my scope. Then I had to ask for my original tube back which took another 1 month. You keep everything and I send you the upgrade. You just unscrew the 40mm tube from the etalon and screw the 60mm tube in. Thats its ... easy.
Sorry US only.
