I got these for my Explore Scientific 80 mm Triplet Essential, then quickly switched to the carbon fiber version. They fit the former, but not the latter. I’ve owned them for less than a month, however, they do so signs of wear (see photos). They will fit an Orion ST80. $20 shipped to the lower 48. Check preferred.
