Thanks, Col. I'm familiar with the Petzval design. I have a Tak FSQ-106ED. I was just wondering why the Vixen is not an apochromat. Does it mean they used the extra degree of freedom to correct something else?
Cheers,
Rick.

There are 2 ' elements ' at the front of the tube.....and 2 ' elements ' at the rear of the tube just in front of the focuser.
Looks very impressive, Col! I look forward to hearing yours thoughts on it
Laurie.....this is a beautiful Scope.... ' WOW ' is the only word I can describe when you look through one..... had to have another one.....so I bought a brand new one.....

Yes.....colour correction and a ' flatter ' field......
see pic's ....also a 5.5" inch APO would be a heck of a lot more $$$$ than this Achromat Scope.
Primarily...this Scope will be for visual use only....very nice wide field flat views with good colour correction.
Just looked at the OPT price. Looks like they used the extra degree of freedom to reduce cost which is a perfectly good compromise to make. An affordable refractor with that large an aperture is a good deal!

I've had a lot of good Scopes over the years....TeleVue...SharpStars....Wi lliam Optic's....Astro-Tech's...Meade....but there was something that didn't quite satisfy my ' niche ' ....until I bought one of these ...Vixen NA140.
This WILL stay with me ...and be my main viewing instrument....and will possibly be the ' last ' refractor I will buy....I have found my ' perfect ' Scope.

You hedged your bet there with the word "possibly" I see Col
Glad to hear it has finally arrived though, a great looking scope.
