Does anyone have any comments about this telescope?  At around $2,000 (different prices at different dealers), the price is certainly right to pique my interest!

How do you want to use it? Visual or AP or both? I think you could compare it to this one from Stellarvue. Both are nice scopes and I have scopes from both. I admit to bias for Stellarvue but in this case I'd call them equal in quality.

So it’s basically an Access on steroids (better build quality).

I would wonder how well a 126mm F7.7 doublet would work for imaging. Sure hope it is mated with Lanthanum at least. Seems a little odd to me that they went heavy duty with the big focuser and Losmandy dovetail on a doublet. Usually the doublets are equipped more for visual and triplets for imaging.

I'm a fan of WO scopes, I currently own one and have owned another.  I'll likely buy at least one more.

However, *right now,* I'd jump on the Stellarview 125.  It's a steal at $1495, and is at least as good as the WO if not better.  You don't get the handle-top or focus mask, but are those worth $500-$600?

In fact, I'm thinking of jumping on the Stellarview myself...that's a terrific deal.

Probably very well. I have a doublet at F/7 with FPL 53 Stars show no color , also not on pictures. It is mated with Lanthanum in my case. Of couse the specs of the 126 mm are different but if well made such a doublet  is quite impressive,

Yes but your model has Lanthanum as a mating element and it has less aperture. Obviously it could work for AP but just seems like a visual scope with an AP focuser and dovetail bar. But that may just be me.

A doublet is right on the edge at f/7.7 for colour/sphero but it should be very nice.  I've always liked the Zenithstars, not so much the Megrez's.

How are the fit and finish? Any small dings or scuffs on the tube?

Thank you.

$2000 is rather steep for a 5" doublet imo. Granted you get the WO brand name and service, but you can easily get a 5" triplet at that price

 I'm sure it has lanthanum as a mating element like all the other 125s. I agree the WO ZS126 is pretty heavy for a doublet being same weight as the WO 132 FLT  triplet. I bought a Vixen 130ED SS F7.4 with FPL153 and lanthanum on Amart a few months ago and it has zero CA even at 460X.  Vic at SV said he still had some 125 objectives  and could make someone a very high strehl  SVX125D . For me it was too close size wise to my WO ZS110 triplet. The Altar 125 is .95 strehl or better . I don't know if the WO ZS126 is. David

I'm on the fence with the ZenithStar 126mm f/7.7 doublet and the Gran Turismo 102mm triplet.

Looking to do more imaging than visual but would like the extra light grasp of the 126mm.

I've heard a good quality doublet will produce very nice images and it's not always a "must" to go triplet but have no experience with Refractor scopes, only SCT and Netwonian.

 

Thoughts? Advice?

If you get the ZenithStar you will for ever wonder about the Gran Turismo. If you get the Gran Turismo you will for ever wonder about the ZenithStar. It's mental 'catch 22'.

 

Me... Because I'm an imager and I've had a Gran Turismo (the GTF 5 element 81mm) I would buy that one for AP work over the ZenithStar.

Here's one positive review of the 126mm doublet:
