William Optics Gran Turismo 71 mm f/5.9 Apo with FPL53 Triplet Lens - RED Reviews
1/1 Reviews
Wrote by Steffen W. on 25.01.2023
"Dieser APO beeindruckt durch seine (Farb-)Reinheit. Den visuellen Mauertest hat er bestens bestanden. Keine Verzeichnungen zu erkennen. Alle Fugen sind gleichmäßig und scharf zu erkennen. Ich nutze diesen vorrangig für die Astrofotografie - keine Farbfehler an den Sternen und keine Eiersterne im Randbereich. ***"
