Optically amazing. You will not find better glass with this aperture at this price point. I am exceptionally pleased with making this purchase and would do so again in a heartbeat. There are a couple minor nits to pick, but every product has them, so I don't believe it's worthwhile to dock stars for them. Like: - 102mm of aperture! - Outstanding optics. Pinpoint sharp stars. Sharpest scope I own, now. - Excellent resolution (~1.14 Dawes limit). - f/5.6 with a 0.8x reducer (compatible with a number of different reducer/flattener brands) - Light weight. - Includes all the backfocus spacers you'll need. Dislikes/Nits: - The carry handle is annoying for attaching peripherals, but not excessively so. - Focuser is quite smooth except at a small pinch point every full rotation, but it's only noticeable when using the gross adjustment knob. I didn't notice the same issue using the fine adjustment knob. - My copy arrived with a small dent in the dew shield. It is unclear whether the damage was missed by QA or occurred in transit, but the package was not in the greatest shape when it arrived so I'm assuming the latter. Regardless, the damage is cosmetic-only and did not affect collimation or performance of the OTA.
