So I was always planning on getting a TS-Optics PHOTOLINE 130 mm f/7 (3.7") towards the end of this year. That one retails for about € 2k.
The similar scope in this new line is this one
What makes this latter scope €600 more expensive? Am I missing something?
From the TS website...
"The color-pure 130 mm apochromat is equally well suited for visual observation and astrophotography. Thanks to the FPL55 APO element, the imaging is first-class and in practice indistinguishable from the world-famous LZOS lenses from Russia."
"The Apos are equipped with new R&P ball bearing slides that support heavy accessories."
"Each CF-APO is optically checked before shipment. A certificate with serial number is enclosed to the apos."
Based on the above statements from TS, I’m guessing that TS wants you to believe that the optical figure on the lens is better, the focuser is up a notch in quality and the scopes are checked before shipping.
Now, that is what they “say”. Whether any of that is true is another question. Is the optical figure “in practice” as good as a lens from LZOS like they say? And what does “in practice” mean? The lens is either as good as a LZOS lens or it is not. Sounds like a marketing phrase to me, unless they can clarify. One might also wonder why the APM/LZOS 130 F6 is TWICE the price of this scope.
Certificates are worthless. Getting a piece of paper does not mean that you are getting a good lens. Just ask if there is a minimum optical quality guarantee on these new offerings and what that might be. And how is that different from similar previous offerings. Also ask if you have the scope independently tested and the results differ, can you return the scope for a full refund?
I’m sure these scopes are fine telescopes but there are some marketing/promotional gray areas that need clarification.
