Hola, seguramente os parezca una tontería lo q pregunto pero es q todavia no lo tengo mu claro. Al introducir una barlow, ya sea pa observacion o foto, se esta duplicando la Focal???? Usease, si mi teles tiene F10, al meterle Barlow estaria viendo en F20???? no se si me he explicado bene.

Gracias y saludos

Exactamente, si tu telescopio es un F10 y le adaptas una x2 obtendrás una relación F20.


Salu2.
