Orion 5560 1.25-Inch Variable Polarizing Filter

This filter appears to do its job, allowing different users to adjust the brightness to their particular preferences. It represents a more flexible and convenient alternative to that of buying several fixed-transmission filters. A more proficient astronomer may be able to shed light (no pun intended) on the disadvantages of doubling the number of surfaces.

There is not much to say: The two parts operate well together, and it does exactly what it is supposed to do.

Economical, good value, well-built. Best Moon filter I have tried. I use it visually on my APO Sky-Watcher.

The quality of these filters is good. The stack of two doesn't cause any discernable image degradation and they provide good control of the light level on brighter objects like Venus, Jupiter, and the Moon. Be advised that not all eyepieces have the same thread. These filters fit most of my eyepieces, but not all of them.

Ich bin sehr zufrieden. Sehr gut geeignet um damit den Mond zu beobachten. Ich verwende es an einem Teleskop mit 200mm Öffnung, 1200mm Brennweite.Besonders gefällt mir, dass ich den Grad der Abdunklung verstellen kann, je nachdem, wie groß der Mond jeweils erscheint.

Creo que está bien para observar con luna llena. Al poder regularlo dejas el brillo que deseas. Inconveniente es que para regularlo tienes que quitar el ocular.El mio daba la sensación de que se había usado, pero como no tenía desperfectos me lo quedé.Actualización: Tras un poco de uso y unos meses después, una de las dos partes del filtro se ha dividido en 2. El vendedor me ha reemplazado el producto de manera muy rápida y eficiente. En cuanto al filtro es estupendo

filtro polarizzatore variabile di discreta qualità utile e funzionale ottimo su giove luna e oggetti molto luminosi.il problema è che ne ho ordinato uno ma me ne sono arrivati DIECI sto impazzendo per restituire gli altri NOVE senza pagare le spese di spedizione.Un po forse perchè non conosco bene l' inglese e la ditta si trova in olanda.
