Well that was fun. I had forgotten just how *dark* skies can get! Thankfully the moon didn’t rise until late in the evening, which left plenty of visual opportunities before bed.
Some of the objects I saw:
- Saturn and Titan with my 30×100 binos – it was easy to make out the rings (though not separate rings), and Titan was there in all its miniscule glory
- It was dark enough to see the Coal Stack
- I reckon I actually saw Eta Carinae without the need of the binos, and of course seeing it through the binos was great fun
- A satellite. I shall need to check stellarium to try to figure out which one it was
- some meteors
So I’m going camping up at Poona for this easter long weekend. Should be fun; fishing, relaxing, reading, relaxing, playing board games, swimming… oh and relaxing.
The skies shouldn’t be too bad except for the moon still being between about 83% and 64% luminous over the 3 nights we’re there.
My star gazing goals for the trip are:
I saw the ISS for about 3 minutes on Sunday April 10th. huzzah! I know it’s been there for years, and will be there for many more, but hey: this is what amateur astronomy is all about!
I’m surprised it was so bright. I saw it with the naked eye and also trained my 30×100 binos on it. It seemed to just be a bright blob; not sure whether i was out of focus, or whether my eyes were failing me (I had been inside all day staring at a computer, and for a good 5-10 mins before the sighting time everything at a distance was doubled)
Unfortunately the long April 11 sighting opportunity was a no-go due to clouds.
So it would appear there is a good 5-minute opporunity to view the ISS from Brisbane / Gold Coast region next week. Hopefully my Arnold Schwarzenegger arms (a pre-requisite for owning 30×100 binoculars without a tripod) will be up to the challenge of tracking it! I don’t think I’d be able to track it with the telescope very easily; that would involve leaning over on a weird angle, trying to find the sat through the finder scope, getting the focus right, using an appropriate eyepiece, and guiding it by hand.

We shall see.
A great night to be viewing the heavens: the temperature has dropped off, not a cloud in the sky, not too much of a breeze. Visual magnitude is about a 6, and earth hour was on lol.
Tonight I saw with my 1200mm 8″ dob (with 25 and 10mm eyepieces):
- Saturn and four of its moons! Titan, Tethys, Dione and Rhea. :O
- Eta Carinae
- Tarantula nebula
- the Alpha Centauri double star
- tracked a satellite for a bit across the sky with my 25mm ep from southwest to south! Thankfully I have Stellarium and there just happened to be a sat passing over the right spot at the right time – Radio-Sputnik 15!
I love it when NASA does this sort of thing… have a watch, it’s really good.
Here’s a direct download of the 400mb 640×480 mpeg file.
On another note it is probably worth mentioning that I saw Neptune for the first time with my 25×100 binoculars a couple of weeks ago (well, a few months ago)… and yes, it is blue!
I also saw the Galilean moons – Io, Europa, Ganymede, and Callisto. They were just dots, but still it was amazing. The binoculars were strong enough, though, to show Jupiter quite clearly as a small disc rather than a dot too.
