3x Barlow lens telescoop Barlow lenzen M42x0.75 draad interface voor 1,25 inch astronomie telescoop oculairs

Ajustado a la descripción, se ve de material solido y encajaba sin problemas en el telescopio. La optica aun no la he podido probar.

I only just started with my telescope however this increased the magnification and seems to work well. Im not sure if the dearer ones are any better but seems ok to me

Profucto que cumple su cometido, sin ser nada excepcional. Construcción con demasiada holgura con el soporte del telescopio.

When I tested this barlow and compared it against my existing 2x barlow lens it gave a slightly smaller magnification than the 2x. I know from imaging the moon at prime focus that my 2x barlow gives a genuine 2x magnification.I was very disappointed in the 3x barlow so sent it back.
