Are these long exposure or is your view of the stars just that awesome (I see 10-12 a night, so seeing more can cause me to have aneurisms and strokes).

A new mix of pictures.

Transits and occultations involving the planets are always fun to photograph since they reveal a sense of scale.


A bunch of ice halos:


Iridium flash:

The shots are taken with about 27 second exposure and a fairly large ISO. The shot right above the panorama is pretty close to what the sky looks to the naked eye.

If you spend enough time looking at the sky, so that your eyes get adjusted to the dark and the sky is clear enough, you start to notice that the sky is not actually dark at all, but a mass of stars. It is really an eye opening experiance.

I occasionally get requests about permission to use that Iridium picture in teaching materials. Most recently it was featured in a 12 lecture DVD series by Alex Filippenko. It's Iridium 19, photographed in 1998, btw.

---------------------------------------------
Satellite flares are very common in Norway (and often mistaken for meteors), since many satellites have polar orbits making the sky pretty crowded here. I posted an animation a while ago showing flares in roughly the same spot on subsequent nights. Here's a new extended version showing the same over a period of more than two weeks (cloudy nights excluded):

There is one picture per night and all are taken at roughly the same time (±15 minutes, check Jupiter to the right). Some nights have three flares in the same area and all these occur a few minutes apart.

I don't know what satellites these are (I couldn't find any matching Iridiums). It's perhaps not surprising that there are several flares in the same area of the sky, if the satellites have roughly the same orientation relative to the Earth and the sun.

Huh. Any chance for rough coordinates and time? I could run it through a sat-tracking program to see what's going through that area.

59.97048N 10.64917E 346 masl. Period: 27th March till 10th April. Looking WNW. Around 22:30 UTC, drifting slightly from before this time to after this time as the days went by, if I recall correctly.

I'm pretty sure those are Iridium afterall. Here's an animation for some passes around 22:30 from March 27 through April 1. Some of those flares were really bright, down to -7 magnitude!



Typical values for the passes (at least for those among the first six nights)
Times: 22:30 UTC, plus or minus 10 minutes.
Azimuth: 250 to 260 degrees
Elevation: 20 to 15 degrees

Yes, that looks like perfect matches, and it went on like that well into April. I've been using the Heavens Above website, and either I recall incorrectly or the site failed to hindcast accurately.

The frequency of -7 and brighter Iridiums increases rapidly further north. In northern Norway, 70N, expect to see a couple of them a day. When you approach 80N or as far as civilisation goes, there are several every day, sometimes as many as around 10. You see them all the time up there and they've become a feature of the night sky. And if you look towards a certain region of the northern sky, you will almost always spot one or two faint satellites within a few seconds.

Wow, all your pictures of the night sky are just awesome! I can't wait until I get my Canon 1000d camera and start taking photographs myself! Unfortunately for me (and us, I see many of you are from the Nordic countries!), living at 60th latitude north, the bright summer nights have already come. sad

This is a picture of the moon that I took about a year ago. Through a small telescope without any other equipment with my phone camera! Not as good as yours, but maybe someone likes it. smile





Love Space Engine!

Nice job! I tried a similar setup with my hunting monocular and my Galaxy S2. Result shown here:
