Description

When looking at the technical data, 70mm aperture may not look too impressive. During the observation the impact of the 36 % more light gathering power in respect to a 60mm refractor are easily visible: Details are seen more clearly in the Bresser Sirius and from a distance of 600 million km the main cloud bands on the planet Jupiter get visible.

With the included smartphone camera adapter you can take pictures of your best observations right through the telescope.
