Which 4" ED/APO for visual?

I would be tempted at that price. I see Andrews has responded with their pricing.

Both shops now selling the ED100 for less than the ED80.

Been out for the last hour or so with the SV110ED looking at Mars & Saturn.

Contrast is good, not as good as a Tak, obviously, but acceptable. A bit of CA that comes and goes with the seeing. When it settles there's a subtle purple glow around only the brightest objects - for example a little on Mars, none on Saturn - but this isn't objectionable to me.

I love having a good focuser again. That was the weak point of the FS-102. The Stellarvue dual-speed R&P is a pleasure to use.

Pretty happy to have the scope back. Some day I'll go Tak again, but for now this will do nicely.

Congrats !

I have the same ED110 from 'Kunming' and have the same experiences. Slight (almost negligible) purple halo around Jupiter, but none around Mars and Saturn.
I use this one as a travel scope as it fits within in the carry-on requirements of the airlines when I remove the focuser.

For me it is for both visual and photo (Canon 6d) use.

Take some beating ,,, both ways .. visual and AP .

Great to see these are getting finally ( Lewis ) appreciated , amongst the best ever made . ( Takitis )

( its strehl is better than the atmosphere we live in for clarity )

I have a 120ed I use for astrophotography and have no problem with CA though it must be there though very slight. As for the focuser , I find it robust enough to hold more than 1 kg of camera with no sag or change in focus. I would think the focuser on the BD 100ed would be a similar 10 :1 focuser. However some of the other clones like Saxon have single speed focusers.

I think all current Synta versions have a dual-speed focuser now.

There's nothing 'wrong' with the Synta focuser but like any piece of kit, once you've used something better it can be hard to go back. I have the dual-speed on the Saxon Newtonian I bought last year and it's good enough but not as solid or smooth as the focuser on my Stellarvue, which in turn isn't as good as a FeatherTouch, etc.
