William Optics Redcat

apochromatischer Refraktor

...ein leichter Petzval Apo für die Widefield Astrofotografie

Der neue William Optics Redcat Apo ist ein echtes Petzval Design, im Fokus hat man automatisch die beste Feldkorrektur und muss keinen Arbeitsabstand berücksichtigen.
Beim Fokussieren wird die ganze kleine Teleskop Einheit im Tubus verschoben, der Helical Fokussierer ist griffig gummiarmiert und die Gängigkeit einstellbar.
Die Optik hat uns im Test überzeugt, die Farbkorrektur ist aussergewöhnlich gut und die Sterne bleiben bis in die Vollformat Ecken nahezu rund.
Testergebnisse siehe Foto Tab. Das Objektiv ist justierbar und die Abbildung kann somit von uns gepflegt werden.
