I recently got an LS-8 and I've gotten first light with it.
The tech is pretty cool but I've still some concerns about cord wrap with the thing.
Optics seem quite sharp right across the FOV with the use of a Plossl. Stars seemed to have a bluish tint and things seemed a bit dimmer than expected - I suspect this is an atmospheric effect and I'm going to want to do some comparisons with other OTAs before I really think this is a problem (I've several other 8" OTAs).
Weird that the card you use to re-load the firmware is a Mini SD. You can still get them but they really should work on updating the tech a bit.
