I do not like finding faint fuzzies.
There. I said it. I’ve always known it but for a long time I’ve been embarrassed to own it. It has often felt like if you’re an amateur astronomer, the whole point is to go hunting for faint galaxies and planetary nebulae. Which is why so many of them get aperture fever and hunger after ever larger and faster mirrors for their Dobsonians.
But I have a refractor.
This is actually a chicken and egg scenario. My – our – first telescope was a Tak refractor, because that’s what James bought me for my birthday. So with that to learn on, I went to what it was good at looking at: planets and double stars. Planets were always going to be one of the great joys of my observing life. I was initially unsure about whether hunting double stars was worthwhile, but with some time and an understanding of what refractor was able to do, I discovered the joy of tracking them down and in particular how awesome it is to look at the differently coloured ones. Having a 90mm refractor meant that looking at faint galaxies was never going to be worthwhile.
But even when James got his 16” Dob, and started chasing faint fuzzies, I didn’t get the bug. In honesty I don’t think I have the eyes for it, and that has certainly added to the frustration the few times that I have joined in the galaxy quest (heh). Plus I just don’t get it. All I see are fuzzy grey blobs that rarely have any shape to speak of (to my eyes) and so… what is the point?
All of this has meant that I’ve sometimes felt on the outer amongst amateur astronomers. As if looking at things that aren’t incredibly hard to find is somehow… cheating? A waste of time? Letting down the community? Demonstrative that I haven’t levelled up to being a ‘real’ astronomer? Which hasn’t been a lot of fun.
Of course this is all at the same time as having people comment that my refractors have excellent optics and that the stars look great through them and the view of planets are wonderfully sharp. I never said it was entirely logical.
Anyway. I’m slowly owning all of my own preferences and desires and peculiarities. I don’t have to go along with what anyone else likes and thinks is right in such incredibly subjective areas. I can look at whatever I like.
If I want to spend the entire night looking at Orion’s Nebula, Jupiter, and Saturn, and then the Eta Carina Nebula in a 31mm Nagler, then that’s okay. And would be quite a nice night, actually.
Of course if James pulled up the Eight-Burst Nebula or the Ghost of Jupiter, I’d sure go have a look at those. Maybe the Grus quartet. But anything from the ARP catalogue? Nah.
Last weekend we travelled to the ASV dark site for the annual star-b-cue, and it was awesome.
We went up on the Friday night. We set up in the early evening and then had to wait around for hours as the sun slowly went down. I did manage to get a good look at the moon, in a lovely crescent – I haven’t made the effort to see the moon in a long time, and it was glorious. That night involved a lot of reminding ourselves of the sky and also introducing some friends to our telescopes. One of them is an exceptional astronomer but from the northern hemisphere, so it was amusing to hear him talk about which bits he can’t see at all from home (like 47 Tuc!). And complain that Orion is upside-down. I didn’t have a viewing plan for the evening so I went with whims. Amongst the best things I saw was two moons around Uranus (Oberon and Titania, apparently) and I split Sirius! Unbelievable! I piked earlier than I had hoped – around 1am I think – I had hoped to see Jupiter but we were in spot such that it was still behind the trees when I was flagging.
Saturday was the actual star party. During the day I set up the solar telescope and various people looked through it; there were, I think, maybe six solar scopes set up – more than I’ve seen at any other time. And the sun was looking pretty fine; not incredibly active but some beautiful prominences and a set of sun spots in a cluster. I also took a wander around the site and checked out the new radio shack they’ve set up, recording the sun, meteors and Jupiter. The guy in charge was very pleased to play us the recording of a solar flare from October.
The evening progressed as these things do. The Lions Club provided a great BBQ dinner; there was a quiz – entirely music based this time, so I did ok; and there were heaps of people. There were dozens of scopes set up on the observing field; I didn’t bother going down to the photographers to check out their set ups. It makes me too sad to see Takahashis being used solely for imaging. Anyway eventually the sun went down, again; I looked at the moon, again, and had to make sure I stopped doing that early enough that I could get light-adapted, given how very bright it was. Again, I had no plan… so I looked at some globular clusters, and some planetaries; I saw some galaxies through the Dob. And I stayed up late enough to see Jupiter. Not a great view, to be sure, but when the seeing snapped in it was definitely worth staying up until *mumble230mumble*. Galilean moons all in a row.
Pretty much exactly what the name says, the VicSouth star party happens every year at the Little Desert Nature Lodge just outside of Nhill. It’s usually held over the Melbourne Cup not-actually-a-long-weekend, and this year I was fortunate enough to be able to go for most of the weekend. I was very excited.
The event itself
… was very well organised. The location itself is excellent for astronomy – James checked the sky each night and got readings to indicate it’s the darkest skies we’ve ever observed under. There’s a big field that’s perfect for setting up many telescopes; there were lots of cables running to power but that’s always going to be the case. The field’s flat, it’s grassed, and it’s near the dining room which meant that the urn wasn’t too far away when it got to midnight and we were cold but still keen.
The location also works well during the day. We splurged and got a cabin – nice to collapse into a good bed – and we also went with the food package, which meant lunch and dinner. The dining room comes with big round tables that seat 8-10, which meant that we were forced to talk to people (the horror!) at each meal – we had some great conversations about astronomy and even other things. And the food was pretty good too. The organisers planned things for during the day, and I even got to some of it despite needing to nap each afternoon to prepare for the night’s viewing. A number of people volunteered to give talks, on everything from the geology of the local area, to ways the universe is trying to kill you; from astrophotography to organising your observing lists. It was a pretty good mix. And apparently each night there was a movie on the screen (including On the Beach), but I didn’t get to those.
I went without any preparation, except for the vague desire to get up and see Comet ISON. Since that’s the only thing that could be called a goal, as of the Friday afternoon, you could say that I failed, since 5am did not see me awake on any morning. Given that a small group of people did get up and then reported that it was a fizzer, I’m not too fussed.
We only got in a couple of hours on my first night before the clouds rolled in. Had a great view of Venus… because for a while it was pretty much the only thing to look at, given its insane magnitude and height in the sky. Also 47 Tuc, which rather started a theme for the weekend… I do love me a globular cluster.
The next night more than made up for the first, though, and we stayed up until about 2.30. I had made a List, and got through a number of doubles before I got distracted. I looked at some globular clusters, including some in the Large Magellanic, which I didn’t realise you could do. I also looked at Uranus and Neptune – to my everlasting delight we bagged Triton, Neptune’s main moon, too. James contributed to my distraction by convincing me that Andromeda through my ‘scope was the best idea, given its wider view; and we managed to see the two other galaxies around it, too, which did indeed look spectacular. He was concentrating on some faint fuzzies, and called me over to test my eyesight on some mag 13-14 galaxies… most of which I managed to see, or at least could convince myself that I did. And of course I greedily admired the Orion Nebula; I will never ever get bored by it. I was sad by how late Jupiter was rising – I saw it through the trees, and the Galilean moons were all in a row, but the view was utter mush.
The last night of viewing was also spectacular, but we sensibly didn’t stay up as late since we had to drive home the next day; so we pulled out at about 1.15. Again, I bagged a number of double stars – to my delight I discovered that I could split down to a 4″ separation! I didn’t think that was possible through the 120mm. I looked a few open clusters, but mostly they bore me; the Ink Spot and cluster of NGC 6520 were pretty cool, though, as the dark nebula of the Spot was quite noticeable with it being so dark. Again I got distracted by globulars, doing so a bit more systematically by dialling up all the globs in Sagittarius (there are so many Messier objects there!) on the Argo and working through most of them.
And there was observing during the day, too. I had taken my solar scope, but someone else had their much-bigger, double-stacked one rigged up next to a white-light solar scope, so… yeh. Mine didn’t come out. I was mighty impressed with his set up: he’d got a piece of core flute, and attached to the scopes, so that they acted as a sun shield. BRILLIANCE. But, um… maybe a little bit TOO attractive….
Last year we became members of the Astronomical Society of Victoria and one of the perks is access to the club’s dark site. Each year they run a few public access events to promote the club and astronomy, so we took it as a good chance to head up – check out the dark site and share our scopes and love of the night sky with some new folks.
We headed up under perfect clear blue skies and set up on the main field – I picked a spot between three big Dob brothers, an 18″, 20″ and 25″. Secretly I hoped they might act as a bit of a decoy for my baby 16″, to keep away most of the crowds, but once again the magic of observing with both feet on the ground seemed to draw people in. Alex set up our 5″ APO next door; she drew a bigger crowd than me!
It was fabulous to see so many people having their first experience of astronomy under a proper dark sky (SQM 21.5 last night). The local Lions Club put on food, the club put on a range of short and interesting talks as well as tours of the site, and after dark one of the night sky.
The evening started off pretty quietly with most of the visitors engaged with the night sky tour but that soon ended and for the next few hours the observing field was awash with the curious, interested and far too many far too-bright red lights. But hey, we’ve all gotta start somewhere.
In keeping with the Charles Messier theme of the evening I made a point to try and show people a few interesting Messier catalog objects as well as a number of the usual showpiece objects. I also always like to show people one or two of the more impressive galaxies that are up too; regularly seeing these objects which put everything else in the sky into context is one of the privileges of owning a big scope.
Over the evening I observed and shared these and more:
M46 OC + NGC2438 PN
NGC 3115 Gal – Spindle Galaxy
NGC 5128 Gal – Centaurus A (saw the bright strip through the dust lane)
M104 Gal – Sombrero Galaxy
NGC 2392 PN – Eskimo Nebula
NGC 3242 PN – Ghost of Jupiter
M42 and M43 Neb – Great Nebula in Orion
NGC 1365 Gal – Zorro is sadly chasing the sunset at this time of year.
NGC 2024 Neb – Flame Nebulae.
B33 Dark Neb – Horsehead (Hb Filter) – With Orion high in the sky it was the easiest view I’ve had of the normally elusive Horsehead, I managed to show Alex and 2 or 3 others who all saw it. Normally I struggle to see it myself, let alone help anyone else see it.
NGC 2070 Neb – Tarantula and region in the LMC
NGC 3372 Neb – Eta Carinae
47 Tuc GC
NGC 5139 GC – Omega Centarus
NGC 4755 OC – Jewel Box
NGC 3293 OC – Gem Cluster
While I wouldn’t want all my observing sessions to be like this it feels good to go and be part of an event like this a few times a year.
