Well, as much I would love to join the Tak VIP club, my current 4" triplet seems good enough for my purposes, so my thoughts keep gravitating towards either a 10" reflector (RC or Newton) or a 5"+ refractor. But most importantly, hopefully the new location will soon allow me to use what I already have more often!
I haven't seen any good images with an FSQ130 yet. The owners must be very shy.
An AP130GTX with the quad corrector giving F4.5 or so may well be better than an FSQ130 but of course its all fun speculation.

I’ve seen one person post some images with a FSQ130 and Nikon D810A at full resolution. The AP with Quad Corrector will be good but whether it has <5 micron stars 22mm off-axis is another thing.
