Asterism: Coathanger / Collinder 399 / Brocchi's Cluster, Square of Pegasus, Summer Triangle / DAVe
Stars: Deneb, Lyra ε1, Lyra ε2, Lyra δ1, Lyra δ2, Mizar/Alcor, Polaris, Vega
Planet: Saturn
Satellite:
 (2)
Meteor

Location: Home
Date: 2017-07-30
Time: 9:00 PM - 11:53 PM
Instrument: Visual + Binocular 10x30 IS + 10" Meade SCT (100 mm + 30 mm eyepieces)
Transparency: Good (3)
Seeing: Good (3)
Temperature: 19º C - 14º C

Clear skies. No wind; a small breeze mid-evening that was barely discernible. First Quarter Moon in the sky.

Saturn
Time: 9:15 PM
Instrument: Visual + 10" Meade SCT, 10 mm + 30 mm eyepiece
The planet was very bright in the night sky. Rings covered the bottom of the plant and I could just make out a broad band on the planet just above Saturn's equator. One of the Moons was quite distant (3-4 times the rings' diameter.

  

Ursa Major (UMa)
Time: 10:15 PM
Instrument: Visual + 10" Meade SCT with 30 mm eyepiece
S&T Chart Reference: 43, 32

All the stars were visible at 10:15 PM but it was 20 minutes later that Dubhe could be easily seen visually. Polaris could easily be found visually.

Using the telescope at 10:44 PM, I looked at Mizar and Alcor, Mizar being the brighter of the pair. 

Cassiopeia
Time: 10:35 PM
Instrument: Visual
S&T Chart Reference: 1, 3, 72

Had no problem identify the 5 bright stars in this constellation.

 

Satellite
Time: 10:46 PM
Instrument: Visual
Passed from Cygnus through the head of Draco, then disappeared.

Summer Triangle / DAVe
Time: not recorded
Instrument: Visual
Despite the Moon, I was able to locate Vega, Altair and Deneb, in that order as they became apparent in the darkening skies.

 M51 (Whirlpool Galaxy)
Time: 10:54 PM
Instrument: Binoculars 10x30 IS
S&T Chart Reference: 32, 43

Using the distance between Alkaid and Mizar, I looked below Alkaid just a little lesss than this distance and saw a faint, grey circular smudge. Not positive it was M51 but it was the only "smudge" in the vicinity. Next time look at the adjacent star patterns to ensure identification.

Cygnus
Time: 11:07 PM
Instrument: Binoculars 10x30 IS
S&T Chart Reference: 43, 32

The Moon obscured the dimmer stars visually. At this time, the constellation was overhead. The stars ζ, η and ι were not easily seen visually. Used Albireo as a way to locate the Coathanger.

Coathanger / Collinder 399 / Brocchi's Cluster
Time: 11:07 PM
Instrument: Binoculars 10x30 IS
S&T Chart Reference: 43, 32

Travelled down the stars of Cygnus to Albireo then found the Coathanger - all 10 stars were clearly identified.

 

Canes Venatici
Time: 11:11 PM
Instrument: Binoculars 10x30 IS
S&T Chart Reference: 43, 32

Decided to look for this constellation and one of the arms of Boötes because the sky in this direction was darker and not affected by the lights of Halifax.

Using my S&T Atlas, I found this constellation lay directly below Ursa Major's handle. Specifically, Cor Caroli (α)was directly below Alkaid; this was easily found visually and I also looked for Arcturus as another guide. With my binoculars, I was able to find Cor Caroli. Jubilation at also being able to find Chara (β) with binoculars! It wasn't until I looked on the internet and at my map more closely that I discovered α was a binary star. I will look more closely next time.

   

Boötes
Time: 11:15 PM
Instrument: Binoculars 10x30 IS
S&T Chart Reference: 42, 44, 53, 55

Saw most of the stars in Boötes except Seginus. Looking at the star Atlas made me want to look for an extension away from the "kite" that contained θ, κ and λ. I located Alkaid and looked one FOV above it and there it was. The 4 stars of the corner were very clear and were in 1 FOV of my binoculars. SkySafariPro helped me identify the names of the stars. I was thrilled to be able to find this group of stars using landmarks as guides.

   

Lyra
Time: 11:35 PM
Instrument: Binoculars 10x30 IS
S&T Chart Reference: 63

Searched for the Lyra stars in this constellation to confirm the two sets of double stars. Lyra εand Lyra ε2 were easily found in binoculars. Following through Lyra ζ, I was able to locate the red and yellow Lyra δ1 and Lyra δ2 respectively. Vega, Lyra ζ, Lyra δ1 and Lyra δ2  were in one FOV and I was able to centre them in the middle of the FOV.

 

   

Delphinus
Time: 11:42 PM
Instrument: Binoculars 10x30 IS
S&T Chart Reference: 64

The 5 stars of Delphinus were visible but were considerably fainter due to the First Quarter Moon.

Equuleus
Time: 11:42 PM
Instrument: Binoculars 10x30 IS
S&T Chart Reference: 43, 32

I looked to Delphinus and after several second found α, δ, and γ Equ. It took a while to find ε with the binoculars. In examining γ Equ, I could see two stars there - γ Equi + 6 Equ. At ε Equ, I could make out 4 Equ and 3 Equ. I didn't take the time to note the colour differentiation (if any) or brightness, Next time?

   

Satellite
Time: 11:49 PM
Instrument: Binoculars 10x30 IS
Satellite crossed my FOV while looking at M31. It travelled from Andromeda to Perseus before disappearing.

Meteor
Time: 11:49 PM
Instrument: Visual
Travelled through Hercules towards Libra but disappeared before leaving Hercules.

Pegasus
Time: 11:50 PM
Instrument: Visual
S&T Chart Reference: 74, 75
Had to go to the deck side of the house to find Cassiopeia and the Square of Pegasus. There were limitations to seeing not only due to the Moon but also due to street lights if I walked too close to the front of the house.

M31 / Andromeda Galaxy
Time: 11:50 PM
Instrument: Binoculars
S&T Chart Reference: 3, 72
I used Cassiopeia and the Square of Pegasus to locate M31 - a grey oval smudge - with my binoculars.
