M62




M62
Globular cluster
Constellation - Ophiuchus
Distance - 22Kly
Mag 6.4

Date 27/5/14
Transparency - Poor
SQM 21.39 (LM 6.3)

Telescope 16" f/4.5
EP - Leica ASPH x205

Sketch notes
This was the last observation of the night and some low cloud had drifted across making transparency poor and difficult to resolve the stars.
It did appear bright with a tightly packed core with a few outlying stars.

M19




M19
Constellation - Ophiuchus
Globular cluster
Distance - 29Kly
Mag 6.7

Date 27/5/14
Transparency - Good
SQM 21.42 (LM 6.3)

Telescope 16" f/4.5
EP - Leica ASPH x205

Sketch notes
Tightly packed core with a slight oval shape to it.

M80




M80
Constellation - Scorpius
Globular cluster

Mag 7.3

Date 27/5/14
Transparency - Good
SQM 21.45 (LM 6.3)

Telescope 16" f/4.5
EP - Leica ASPH

Sketch notes
Bright and tightly packed although all the stars can be resolved to the core.

Distance 21Kly
Mag - 7.9

Date 27/5/14
Transparency - Good

Telescope 16" f/4.5
EP - Leica ASPH zoom x205

Sketch notes
Fairly large and open cluster with bright stars that are evenly spread even towards the core.

M51




M51
Constellation - Canes Venatici
Spiral galaxy
Distance - 27mly
Mag 8.39

Date 2/5/14
Transparency - Excellent
SQM 21.6 (LM 6.4)

Telescope 16" f/4.5
EP 14mm Delos x135 (TFoV 0.32')

Sketch notes
Compared to the previous observation of M101, M51 was just an explosion of bright twisting arms. At first these arms appeared to circle around the core but when my eyes had settled I started to notice faint breaks in contrast which showed two large arms extending 180˚ from the core.
The bridge connecting M51 to NGC 5195 was just seen with direct vision.
Again this was just off the zenith in perfect transparency, easily the best I have ever seen M51.

M101




M101
Constellation - Ursa Major
Spiral galaxy
Distance - 22mly
Mag 7.9

Date 1/5/14
Transparency - Excellent
SQM 21.51 (LM 6.4)

Telescope 16" f/4.5
EP 14mm Delos x135 (TFoV 0.32')

Sketch notes
Just a few degrees of the zenith with excellent transparency, this was the best I've ever seen M101 although it still took my eyes a while to adjust and get used to how dim it is due to its low surface brightness. The sketch makes the spiral arms look alot more pronounced than what they actually look like.
I would have liked to increased magnification and maybe try a UHC but nudging the scope at those altitudes was just too hard, I'II come back to this sketch another time and try to add more detail.
Two bright patches were seen, at the top was NGC 5450/5447 and the bottom arm showed another hazy patch which I think was NGC5462.
