Mizar and Alcor RGB

By |2020-04-12T17:03:46+00:0012 April 2020|Categories: News, Other|

Something to image in the strong moonlight. Mizar (Zeta Ursae Majoris) has 2 partners: the brighter one you can see is 14 arcsecs away at mag 4 but there’s also one at 0.04 arcsecs separation and mag. 2 that we can’t see separately. Alcor is a binary too with an 8th magnitude red dwarf companion, 1 arcsec away from the primary.

Wide angle Milky Way shots from the Languedoc

By |2019-08-07T20:42:30+00:004 August 2019|Categories: Milky Way, News, Other, Wide Angle|

So – because there’s no night in Scotland from May to August, I went south to the Languedoc hills. Sainte-Polycarpe in the Aude region to be precise. First real use of my Skywatcher Star Adventurer mount. Great fun, still a lot to learn, but got some decent images. Also made a fun little video story of my holiday in a beautiful region of France.
