SVBONY SV137 Lente Barlow 3x excelente compra!!

El Lente Barlow 3x fue una mejora significativa para mis oculares y mi telescopio. Los materiales son de buena calidad, lo recomiendo mucho, pero hay que checar si se ajusta a tu telescopio, porque si lo usamos con demasiados aumentos la imagen pierde luminosidad.
