Dorset Binocular Observations – Tuesday 1 January 2013

Location : Poundbury, a garden
Conditions: Clear. Mild.
Equipment: Celestron 15×70 Binoculars
Highlights: Jupiter, M45 Pleiades, M31 Andromeda Galaxy, Orion, M42 Orion Nebula

First bit of observing in ages. Weather has been poor recently – wet and cloudy. I’ve also been very busy with the whole Christmas thing. The only times there has been a clear night I’ve either been out or needing to crack on with the online Astronomy course I’ve been doing. It’s frustrating to not be out observing because of it but with coursework and deadlines the study has to take a priority.

We were staying with friends in Poundbury, Dorset for New Year. Being a “model village” designed on environmental ideals, the brainchild of Prince Charles, light pollution is well under control My friends also live on the edge of the village so the skies were quite dark, despite a waning moon a few days past full. We popped out several times during the evening for a quick look. I hadn’t taken the scope down so we were using my 15×70 Celestron binoculars. Unfortunately we had to hand hold them as the tripod clamp had been damaged in flight back from the Oman trip and I hadn’t realised.
Jupiter was up high and bright with all 4 moons visible through the bins. Mike was quite impressed with it. He hadn’t seen the moons before. Jupiter is sitting in Taurus at the moment, very close to the Hyades cluster so there were a lot of stars also visible in the same field of view. I also pointed out the Pleiades nearby, which is a nice and easy binocular object. A little later when Orion was up high over the house we were out again looking at the M42 Orion Nebula which really was glowing. I think this was the best I’ve ever seen it. Giving it a few minutes through the bins also brought out more detail. As a final treat I showed them the M31 Andromeda Galaxy, 2.5 million light years away. This was trickier to spot as it wasn’t visible to the naked eye so needed a bit of a star hop. Both Rich and Mike found it after a few attempts. Again, with continued viewing it became more distinct and bright. I really enjoyed showing them a few interesting and rewarding objects. I think they were impressed with what they were seeing with just binoculars.

Observations – Wednesday 21 November 2012

Location : Home, next to the bench
Conditions: Clear. Had been raining earlier so damp.
Equipment: skywatcher 130 scope, AsdaCAM
Highlights: Jupiter, Auriga, M36-Pinwheel Cluster, M37, M38-Starfish Cluster

17:30 1st Quarter Moon, Jupiter
As I left work this evening the skies were reasonably clear with a quarter moon shining brightly to the South, after over a week of cloud. While driving home along the dark A38, I also spotted Jupiter up in the East. Was looking forwards to getting out when I got home.

21:00 Jupiter
In and out of the garden setting up while I was doing the tea. Got out to start observing just before 21:00. Spent until about 21:30 imaging Jupiter to the East before it went behind a fir tree. Used the AsdaCam. Used some of what I picked up from the Bromsgrove Astro session on webcam imaging on Monday. Found that I could shoot at 1280 rather than 640. Also ran it at the fasted frame rate I could in Sharpcam. Used the histogram to get the best exposure. Also picked up on the fact that Jupiter rotates quickly so kept my captures down to 45 seconds. I also captured some over exposed video so that I could combine the moons, 3 of which were visible in a line of to the the right side. It’s a shame that it went behind the tree when it did, as a Great Red Spot transit was due between 21:30 and 23:30. I’ll process the images in the next few days.

21:40 Auriga, Capella – Alpha Aurigae
The space to the left of the fir tree to the east was filled Auriga. Another new constellation that I can identify easily to help find my way around the sky. Capella is it’s brightest star.

22:10 Pinwheel Cluster – Messier 36 , Open Cluster in Auriga
I was intending to try for the Double Cluster next between Perseus and Cassiopeia but that part of the sky was right up at the zenith and I couldn’t get the scope there without it fouling on the tripod mount. So instead I used SkySafari+ to find out what was in the vicinity of Auriga. Delighted to find there were 3 Messier objects, all open clusters. So there’s my objective for the evening. I started with M36, the Pinwheel cluster. An easy starhop from Elnath-Beta Tauri via Chi Auriga. This was a rewarding target. It was a bit boring at first in the 25mm but stepping up to the 17mm Plossl eyepiece and spending time at the eyepiece brought out more stars in the cluster. It didn’t have a particularly recognisable or distinctive shape but I think that will come from more time spent on return visits. This is one of the targets in the Sky at Night Deep Sky Tour for November 2012. I also got the Turn Left at Orion book out to compare notes.

22:43 Messier 37 Open Cluster in Auriga
This was a tricky starhop. I tried from Elath first and got lost so tried again from Theta Auriga and found it on the second attempt. I was hopping using quite faint stars and it was pleasing to be doing so with confidence. My starhop skills with the RACI really have improved. M37 was just about visible in the RACI. Moving to the scope and looking through the 17mm Plossl I was struggling to make out any detail other than a fuzzy. There was a bit of thin cloud about but this was reasonably fast moving so not too much of a problem. The glare of the street light was not helping either. I had my baffle screen out but I couldn’t get it close enough to the scope without having to move everything and without it obscuring the sky. It was difficult to resolve individual stars but it was definitely there as I could make out the fuzziness. I was a bit surprised by this as SkySafari+ was claiming it to be quite a bright object. Changing to the 25mm in an attempt to improve the brightness of the image was actually worse and I pretty much lost it altogether. Checking in Turn Left at Orion helped and reassured me that I was looking at M37, 4,600 light years away as it described it as fuzzy and challenging. It also suggested that in a small to medium scope it wouldn’t resolve to individual stars and looks a bit like a globular cluster.

23:02 Starfish Cluster – Messier 38 Open Cluster in Auriga
My favourite cluster of the evening and my 3rd new Messier in this session. Takes my count up to 11/110. SkySafari+ didn’t know why it’s called Starfish but I think it does look a bit like one. It certainly seems to radiate out from a centre. The 17m eyepiece is definitely the eyepiece of choice for these Open Clusters. Again this is a cluster that rewards patience and persistence at the eyepiece. It’s resolving into stars well and there is some nebulosity there. The seeing is quite still now.

23:31 Crab Nebula – Messier 1 Nebula in Taurus
Tried but did not find. Needs to be a target for the next few days. I’m adding it to the general list on my observing plans. It should be just above Zeta Tauri on the lower horn of Taurus but I’m having problems reorientating myself now. Might not have been helped by moving the scope down the garden a bit without going through a full realignment.

23:45 Packing Up and Conclusions
Just before packing up I noticed that Orion was up to the South East. Some treats in store here in coming weeks, I think. I also had a quick look at M45, the Pleiades through the binoculars which is always a treat. I do love the way they glow blue. The nebulous glow is just visible with the naked eye which draws me to them when just gazing at the sky. It was a cold evening tonight but that wasn’t a problem. Was wearing my snowboarding base layer, walking trousers, hiking boots and socks, hoody, body warmer and waterproof. Also had on a hat and scarf and my North Face eTip gloves were essential to working the laptop trackpad and the iPad. Time to pack up as lights have gone on around the house now as A heads to bed. Called to through the window so had to go into the house so my night vision is shot now anyway. One thing I noticed this evening is that now the leaves have gone from the trees there is more sky available but there is much less shade from the orange glow of the streetlights. Making these final notes I notice that the cloud has come in and only Jupiter and Capella are visible now. The cloud has been drifting across all night but with some pace so has not been a problem. It’s been a good observing session. I’m very pleased with the three new Messiers.

Another Night Out, Another Clear Sky – Saturday 13-Sunday 14 October 2012

Location: Walking home
Conditions: 4 or 5 pints, 1/2 pint pork scratchings, chicken tikka in a naan
Highlights: Oxjam, Moselele, beer, friends, pork scratchings, music, Jupiter, Orion, M45 Pleiades

Had a gig this evening playing at the OxjamBrum festival with my uke band Moselele. Afterward I stayed out around town with friends taking in some of the other bands. I had a great time. I got the taxi to drop me at the kebab shop and I walked home from there. Once again, as previously commented whenever I go out, it turns out to be a nice clear night.

I had had a couple of beers so I’ve pieced these observations together from my tweets at the time.

01:30 Walking home I noticed Jupiter shining bright and Orion was up and nearby the Pleiades open cluster, M45 was very noticable as a blueish fuzz.
Arriving home, I popped back out quickly with the bins for a closer look. Standing in the street with a pair of binoculars at 1am – that’s not odd behavior is it?

Shangri La, Muscat, Oman Observations – Thursday 4 October 2012

Location: Barr Al Jissa Shangri La Hotel, Muscat, Oman
Conditions: Clear
Equipment: Naked eye, Celestron Skymaster 15×50 binoculars
Highlights: Mars,

18:00-ish watched the sunset from the sea having a bob. Best way to watch the sun go down. The resort had a Lazy River running through it – a long loop styled on a falaj (Omani irrigation system used to bring water from the pools in the upper reaches of the wadis to the villages) with water jets to keep it flowing. We had one last float around on a rubber ring round this from where I could see a few stars coming out and in particular Mars high to the West.
We returned to our room via the pool where I had a moment lying on my back in the empty pool looking up at the stars at the zenith. The moon was not yet up. Once again Cygnus was at the zenith and I could just make out a faint fuzz of the Milky Way across to Cassiopeia. That’s quite a way to see it I suppose and in some ways summed up the great day we’d had doing very little around the resort, just reading and messing about in the water.

We ate on the Corniche in Muttrach at Fast Food and Juice Centre cafe again, which serves great shawarma, felafel, hummus and a really refreshing lemon mint drink. A Tunisian family at the next table struck up conversation in a mix of French and English. They lived and worked in Oman and were very hospitable, inviting us to their home, which we had to decline as we were flying onto Dubai the next day. When we came to settle our bill we found they had very kindly paid it. “Welcome to Oman!”. This friendliness and generosity seems to be very much part of the culture and having travelled and been hassled in other countries was very surprising and refreshing. All too often you think that somebody has an angle. Whilst you should never be naive, people in Oman and generally and genuinely nice.

11:20 Back at the room, another observation of Jupiter through the bins. Didn’t sketch this time but did take a screenshot with SkySafari+ just to track the Galilean moons again.
screenshot from SkySafari+ Where is Io though?

Having sketched and tracked the positions of Jupiter’s moons nearly every evening I ought to make a chart of my observations to show the day to day movements. I know there is one printed in Sky at Night magazine each month but it would be interesting to compare and confirm my observations.

I also took some photos of Orion. I’ll have a go a stacking and processing them later, when I’m back home and it’s a cloudy night.

This was my last night of stargazing on this holiday. After this we had a couple of days in Dubai before returning home. This had been an incredible holiday. It was very much a holiday and all the stargazing I did was a bonus extra. I tried not to let it dominate but at the same time took the opportunity where I could.

Shangri La, Muscat, Oman Observations – Wednesday 3 October into Thursday 4 October, 2012

Location: Barr Al Jissa Shangri La Hotel, Muscat, Oman
Conditions: Clear
Equipment: Celestron Skymaster 15×50 binoculars
Highlights: Jupiter, Orion, M42 Orion Nebula, Trapezium

We left the desert and spent a day exploring Wadi Bani Khalid. We swam in the clear freshwater pools of the canyon up in the mountains. We wouldn’t need to visit Wild Wadi back in Dubai after this. I crawled down into the Mukhal cave with my headtorch and before long was quite deep within the cave where it was very hot and dark. Turning a corner and taking care to be able to trace my route back, I could hear running water. I headed towards it for a few minutes and it got louder but I never saw the waterfall that’s supposedly in there. I was conscious that A was waiting for me outside and didn’t want her worrying so I headed back.
It was over a three hour drive back to Muscat and with some fun stress with the traffic we finally arrived at the Shangri La, Barr Al Jissah well after dark.
I had high hopes for this as a decent place for some stargazing. Before we’d headed out to Oman I’d had a discussion with somebody on Stargazers Lounge that suggested it was a good site. The resort is quite isolated, in it’s own grounds, some way South of Muscat. We had a seaview room so when we arrived there were dark skies out over the sea to the East.

12:48 After a late dinner I went out on the balcony and set the binoculars up on the tripod. The moon was out, about 3-4 days past full but very high so almost out of sight from the balcony. It did wash out the sky a bit but looking east there was no orange glow of light pollution. As I’ve done every evening I’ve been able to on this trip, I took a look at Jupiter and made a quick sketch of it’s moons.

It was interesting this evening and I needed to use SkySafari+ again to identify and locate moons. Io was in front and on the edge of the disk of Jupiter. I couldn’t make it out individually but there did appear to be a slight notch to the disk. It was hard to be sure if this was being caused by the shadow of Io on the disk or was just an artefact of the fact that the disk is very bright. It might have been due to a bit of flare or radial spiking. I get that sometimes due, I think, to my contact lenses.

12:55 Orion was up and on it’s side.

M42, the Orion Nebula was clearly visible as a smudge to the naked eye. It showed up well in the binoculars and seemed to surround a couple of the brighter stars. One of these brighter stars was actually the open cluster known as the Trapezium, although I was unable to resolve that to individual stars in the bins.
Observing M42, the Orion Nebula means another Messier Object spotted, taking my tally up to 8/110.
