Thanks guys, though I maintain I've got nothing compared to Antza's work. smile

One more for M31.

Nice ones, Wats! The technical details?

Sure thing:
Canon EOS Rebel T3 @ 18mm (EF-S 18-55mm f/3.5-5.6 IS II lens)
20s @ f/3.5, ISO1600
Tungsten white balance (raised to 4200K; incandescent might have been better)
RAW format with post editing in Gimp/UFRaw.

The first two were taken at Mount Baker, where the sky is pretty dark (limiting magnitude 6.6-7.0) though the rising gibbous moon degraded sky quality a bit. Reasonable trade-off for illuminating the volcano in the second shot. smile The third was taken on my deck (limiting magnitude 5.5-6.0), with no moonlight.

I've got the Rokinon 16M-C 16mm f/2.0 lens on my Christmas list, can't wait to see how that performs in comparison to the zoom.

I have almost no zoom lenses because of the speed loss, but zoom lenses aren't such a show stopper for low light photography as they used to be (back in the analogue days).

Looks like a meteor, but it partly travels in front of terrain and it only appears in one frame of a video. So most likely it's a cosmic ray artifact. The biggest one that I've seen, though. Close up:

That's definitely NOT a meteor! If it was, it would go behind the terrain. I think a single cosmic ray sneaking through Earths magnetic field is definately possible, especially since you live closer to the north pole where they (along with solar wind) play a part in the formation of the Aurora Borealis.

Also, What are those black boxes? Are there vehicles there that you (or your neighbors) didn't want to be shown online?

I thought cosmic ray strikes usually appeared as specks. They sometimes appear linear? Seems like it would take a very improbable intersection angle on the sensor.

Close-up of the Andromeda Galaxy with just the DSLR and tripod (no tracking mount). Even got M32 and M110!

Great job! But I am jealous of your sky. This is what it looks like where I live under the best circumstances (single exposure). M 110 is barely visible.




Keep the photos coming Wats!

My camera with a 300mm lens is almost exactly as capable as Galileo's telescope was (low-light and wide-field abilities aside). When I take pictures of the Moon, or Jupiter, or Saturn, I see almost exactly the things that Galileo saw; in fact his sketches and descriptions match my images almost perfectly. I feel a personal connection to history when I capture and view those images, it's a wonderful thing.

That actually looks extremely similar to my raw frames. Here's one with no editing, just luminance desaturation and rotated to be in same angle:



I bet you could get really good results with RAW & stacking, even with the light pollution. smile
