Cons: QA issues (focuser not adjusted properly on delivery, focuser locking lever fell off) and missing accessories, all of which required me chasing up the distributor. Ultimately got everything sorted but it took a while.
Never had to adjust focus throughout the night before on any of the other aforementioned scopes, but this one needs it done very frequently. Most nights I can see the FWHM go up in every 8min sub. You'll either need lower standards for focus, be happy babysitting it a lot, or automated focusing.
Bottom line: Very solid performer. Would buy again.

could it be because it is that much sharper that you notice the focus drift more easily?
