TS-Optics Doublet SD-Apo 102 mm f/7 - FPL53 / Lanthanglasobjektiv Bewertungen

Geschrieben von Bruce C. am 27.02.2025

"Perfectly suits my use case. The views are astounding! I'm able to see Venus without flaring or turbulence. Same for Sirius. I am coming from an F10 102mm achromat, and apart from the improved views, it's much more portable and lighter. I love the compression ring for the diagonal as well. My one criticism would be mounting the TS reducer/corrector made for this scope that I also purchased. It requires either a tiny slot screwdriver or a 1.5mm Allen wrench (removing the compression ring requires one, removing the next ring requires the other, I don't remember which was which). This took several exchanges with support to understand what needed to be done, and is not something i want to do in the dark on a cold night. Something more consistent and universal would be welcome here."

"The scope is lightweight and robustly built. The focuser and the quicklock system is surprisingly high quality, given the price point. The optics is really-really good: tested at 186x with a binoviewer on Mars, Jupiter, Venus and at 50x on M42. On Mars you can see surface details and the polar ice cap, no CA detected. Jupiter was also very sharp quite some surface details could be seen, no CA detected. Venus was a bit disappointing, it's a very bright object and CA was detectable in the blue domain. M42 was excellent with pinpoint stars and cotrasty nebulosity. Tested few days after new moon. Overall, the scope is easy to handle and delivers excellent optical performance. The only thing I was missing is a handlebar, but you can purchase it separately. Highly recommended"

"Sehr gutes Preis-Leistungs-Verhältnis. Der Apo ist hochwertig und sauber verarbeitet. Erste Aufnahmen auch ohne Flattener zeigen nur minimale Randverzerrungen und keine chromatische Aberration."

"Voll zufrieden. Eine Fluse im Refraktor wurde zügig entfernt."

"Über die optische Leistung kann ich noch nichts schreiben, da es noch an CS fehlte. Aber die Verarbeitung und der gesamte Eindruck ist sehr gut."
