Messier 85 and NGC4394
Messier 85 (NGC4382) is a quite bright and easy target both for visual and photographic observations. It can be spotted with binoculars, and is an easy catch for larger telescopes. But if you expect t... Read More
NGC5033 spiral galaxy
NGC5033 is not in the primary or even secondary list of astrophotography targets. This spiral galaxy lies about 40 million light years away and can be found in the constellation Canes Venatici (Huntin... Read More
Menkalinan – spectroscopic binary star
Menkalinan (beta Aurigae) is a spectroscopic eclipsing binary star system. The two components appear as single star to the visual observations, but their orbit plane is almost aligned with our line of... Read More
NGC3718 and Hickson 56 in Ursa Major
This object was on my astroimaging target list since I remember. I am perfectly aware that imaging galaxies under suburban sky is pretty demanding task. I also know, that one clear night would be prob... Read More
Big Dipper cluster – Collinder 285 spectra
Big Dipper is a large asterism – a part of Ursa Major constellation. Asterism stars do not necessarily belong to the same constellation, and also may not be gravitationally bound. But this is no... Read More
Pleiades spectra
During last observing session I pointed telescope with attached spectroscope to well known Pleiades open cluster. It is also called “Seven Sisters” cluster, because this is the usual numbe... Read More
HD15558 – the most massive star in the Milky Way
Last session with LowSpec spectroscope was only a few hours long due to weather. But still it was enough to capture some spectra of Be type stars, but not only. I also pointed telescope to Melotte 15 ... Read More
Amateur measurements of radial velocity
Since you are here you probably are interested somehow in astronomy. And you probably already are aware of terms like Doppler effect or radial velocity. In ancient times, when I started to read about ... Read More
