Observing Log 26/5/2018, LRO, Lichfield, UK, Andy and Damian.
Damian came around to my house and he demonstrated that the iPad Air 2 that he owns works with my older SkyFi wireless box on my Synscan EQ 6 mount – important as I need to upgrade my very old iPad and have been considering what is the best option to replace it. Earlier today, I had great difficulty getting my Windows 10 laptop to link to it, ruling out the option of a windows-based tablet.
The sky is quite bright tonight with a virtually full moon. For a bank holiday Saturday, the main A38 is quite noise at this time of night – unexpected. Also, it is very windy. Thunder predicted later in the night. On the positive side, Damian is having a whale of a time playing around with his laptop controlling the mount whilst I write this!
ISS (ZARYA), Satellite in Ophiuchus,26 May 2018, 23:22:36, Just watched the ISS rise over my house and brighten greatly as it rises higher until it was a spectacular sight near culmination and then slowly fade as it moved to the east.
Bode’s Nebulae – Messier 81, Spiral Galaxy in Ursa Major,26 May 2018, 23:43:23, Took two attempts at alignment to get scope working well tonight. This is often the case. I have read online that it may be due to backlash when the user must fiddle back and for with the controls to centralise alignment stars, causing errors to creep in. Second time lucky today! M81 proved that alignment had been successful by appearing in the centre of the field of view. It only appeared as faint smudge with brighter nucleus – and looked smaller compared to our usual view, again demonstrating the poor sky. Currently, we are using my Explore Scientific 14mm 100-degree field of view eyepiece.
Hercules Cluster – Messier 13, Globular Cluster in Hercules,26 May 2018, 23:49:41, Top left of view of field so not quite spot on re GOTO but is putting objects in field of view of 14mm eyepiece tonight.
Whirlpool Galaxy – Messier 51, Spiral Galaxy in Canes Venatici,26 May 2018, 23:50: 39, which means that the fact that we could not see this pair galaxies demonstrates again the poor sky quality as we would expect to see it with this scope from this location.
Messier 92, Globular Cluster in Hercules,26 May 2018, 23:51:35, Seen but difficult to resolve stars similar to limitations in our view of M13 – I think sky is not transparent even though can’t see the cloud easily.
Ring Nebula – Messier 57, Planetary Nebula in Lyra,26 May 2018, 23:52:44, Better view but higher in sky. clear Outside app suggested 68-90% cloud by midnight – not that from here but still there is something obscuring view, suggesting the app has identified correctly deteriorating sky conditions.
Double Double – Epsilon1 Lyrae, Double Star in Lyra,26 May 2018, 23:54:44, With 14mm eyepiece we can just about split each of pairs.
NGC 6229, Globular Cluster in Hercules,26 May 2018, 23:57:31, Visible without too much difficult. Mag 9+ so surprising we can see it but prob as high up. This is a globular that we rarely look at – in fact, I can’t remember seeing it before. Not a bad one – recommend folks add it to their observing lists!
Kuma – Nu1 Draconis, Star in Draco,26 May 2018, 23:59:52, Lovely bright easily split double – to me looked like white and yellow/white stars, about same brightness.
Cat’s Eye Nebula – NGC 6543, Planetary Nebula in Draco,27 May 2018, 00:01:04, In Draco too, easily seen as out of focus star.
17 Draconis, Double Star in Draco,27 May 2018, 00:02:55, To me this double star looks like blue white and yellow white pair.
100 Herculis, Double Star in Hercules,27 May 2018, 00:04:03, A little known and little seen double star pairing, Sky Safari says – but we saw it tonight!
Omicron Herculis, Variable Double Star in Hercules,27 May 2018, 00:05:39, I could not split this even with 6mm Ethos, but it did not appear round but oval suggesting the double. These are 0.1 arc seconds apart, so we were asking too much of the scope in this sky to see this.
Nu Herculis, Variable Double Star in Hercules,27 May 2018, 00:10:55, Could not split this either – 0.5 secs.
(With all these double stars, we feel like we are following IN Nick’s footsteps!)
b Herculis, Double Star in Hercules,27 May 2018, 00:12:50, Can’t split this either tonight – 1.4 arc seconds.
Mu Herculis, Double Star in Hercules,27 May 2018, 00:15:31, these stars are 35 arc seconds apart according to Sky Safari app in the iPad. To me, the second one is much fainter than the primary component – easily seen pairing.
Sarin – Delta Herculis, Double Star in Hercules,27 May 2018, 00:20:26, Strange that we could not see this double star at all, even after checking the alignment of the mount to ensure that we were pointing at the correct location in the sky. Possibly the reason we can’t see it is that the sky is deteriorating. It is starting to feel like rain soon and the sky has a varying tint across it which suggests high moisture content and formation cloud. We will try to view M13 again. That will be a good test of sky conditions….
Out last object we viewed tonight: Hercules Cluster – Messier 13, Globular Cluster in Hercules,27 May 2018, 00:23:20, We could just about resolve some stars but not a great view. Time to pack up.
