The Leo Triplet

This is a group of galaxies in Leo, the Lion constellation that dominates spring nights. M65, M66 and NGC3628. At distances of 35, 42 and 37 Million light years, they form a fysical group in space  Tidal forces rip apart the extremities of NGC3628. The smallest galaxy identified in this image is PGC1423398 at a distance of 2 Billion light years: so glad those fotons travelled that distance in space & time only to get caught in my camera!!

M51: the Whirlpool Galaxy in Canes Venatici

This is a famous sight: Messier 51, also known as the Whirlpool Galaxy (not hard to see why!) in the Hounting Dogs constellation (Canes Venatici).

I remember being able first time ever to see this galaxy with 8×40 binoculars when I was 14. That was a major achievement back then.  We spent the night under the stars in April with three friends, and as the spring sky is not very rewarding to binocular users, at least this one made our hearts beat faster.

In this picture, images from last year in April are combined with images from February 15th, 2018. All are taken with the C11, Nikon D750 and now in February with the ASI174MM as a guiding camera, replacing the Lacerta MGEN for off-axis guiding work.

The ASI174MM has delivered every time since it’s purchase in January a decent guiding star. With PHD combined with BackYardNikon the guiding goes excellent.
