Product description

Carbon Fibre Tube

This apochromat is well suitable to visual observing but was, in fact, developed especially for astrophotography. Use the advantages of a carbon fibre tube: it is particularly light and so even perfectly suitable for using on smaller mounts. The tube also offers a very high inherent stability and only minimal thermal expansion. These advantages are particularly useful for astrophotography, as the focus remains stable for the whole night. The dew shield is also carbon fibre and can be extended easily. In addition, the tube is lined with black felt.

TS Optics is a brand of Teleskop-Service.
