New mount for TAL 200K: Synta EQ6

Last week I got a new mount for the TAL 200K. Problem with the old mount was, that with high magnifications of more than 200x focussing became more difficult (much too wobbly). The EQ6 can take the 11-kilo TAL OTA easily. It can carry up to 22kg. The first lunar

Some digital images of Venus

On May 18th and 19th I took some images of Venus in the western evening sky. Venus is still very bright with a magnitude of -4.0. Through my big binoculars it looked like a small crescent moon. At the moment about 1/10 of the surface is lit by the Sun. Looking through the telescope I realized how big the diameter is at the moment (49.1"). Here are some images I took during .......follow this link to read the full report

Deepsky Top-100 (11): Y Canum Venaticorum or La Superba

In Canes Venatici, the hunting dogs, you can find a beautiful red star, Y Canum Venaticorum, or “La Superba”. Y CVn is a carbon star. Most of these class C stars are evolved cooling giants with a large abundance of carbon dust in their outer shells.
