Forensic photos of ED-X2 104mm
These were taken so that a remote buyer will see ahead of time "worst-case" dust and "imperfections" in the lens, even though they're not readily visible to the naked eye under most lighting conditions.
Lens dust has been blown with a bulb and dusted lightly with a soft lens brush - not cleaned (with fluid) or rubbed.
Camera lens is set to f/1.4 and overexposed two stops to make the dust visible.

Twin 90mm SolarMax II with Rich-View Tuning & BF30
- mounted on a William Optics Megrez FD-90.
Two SolarMax II 90mm external Etalons with Rich-View Tuning (if I recall, they generally don't recommend having two with the tuning, as it's an extra variable in the lightpath to tune...).
The etalons mount to the aluminum tube via the stadard adaptor (AP190). The aluminum slides over the FD-90s dewshield. Felt-tape provides a snug marring-free fit. A Losmandy dovetail is mounted to the aluminum tubing; the dovetail is hex-screwed to the FD-90s Vixen Dovetail. Removing the etalons for visual observing is done by removing the two screws to the Vixen dovetail and sliding off the etalon/tubing/lostmandy-dovetail unit.

Sky-Watcher Quantum 120ED F7 Tripliet
This is the precursor to Sky-Watcher's renowned Esprit series of triplets. This apparently is the same cell as the Esprit 120, but decked out in Carbon Fiber.
I wanted the biggest refractor I could fit in the "Bay Room", set up and ready to view. I also am fond of carbon fiber: it's a good look, it's robust and it hides blemishes well.
In it's case (which holds its accessories (the 50mm right-angle finder, bracket, custom flattener, diagonal), it's a bit to big to be a "grab and go" scope. With a heavy Berlebach tripod, it's a bit cumbersome for quick views on the patio, but it works. It really is the biggest refractor to leave set up inside that's ready for quick viewing.
I bought this from a guy in the very humid deep south a few years back. It had some issues that a purist would object to: the focuser locking nut was unlockable (to no ill effect) and the glass wasn't perfect. He had some spots between the lenses from the humidity. He pointed at the sun to dry out/kill the issue. I've seen zero additional issues in the intervening years (desert southwest is a far friendlier clime).
Considerably more detail on Jupiter (my baseline) than the 4-inch APOs I've had. Better views than the 120mm FPL-53 doublets I've had. This is a very capable refractor; I don't see ever needing anything bigger. Ever.
