Is the Pentax K-5 good for astrophoto?

Hi everyone!

I am looking for a good camera to start photographing the night sky.
Mostly just stars and such, I don't have a telescope.

What I would like to do is setting the camera for long timelapses throughout the night.

I would be very thankful if anyone have got any photos or information regarding the K-5 and night sky photographing.

I'm kind of new into this so I haven't got too much knowledge about what to think about.

At the moment I am using a Olympus SP560UZ, but it's not very good with the ISO settins and the sensor easily get's warm and produce light pollution on long shutters.

Thankful for help!

Sincerely,
Peter

the longest exposure I did was slightly over 2 minutes, but the noise was remarkably low. I think it is among the best. Also Canon DSLR cameras have long reputation of handling the long exposures very well.

Thanks a lot for the reply!
I see, that sounds very promising!

You wouldn't happen to have some shots to share?
Would love to see it in action.

This was a 78 minute exposure. I came out nearly white as there is a lot of light pollution in the area but, the K5 is more than up to the task IMO.

Here is a 4+ minute on a different night with a different lens.

Wow those are really nice shots!

As you don't mention the post-processing stage, may I ask how it was?

The truly amazing thing about the K5 is not it's high ISO capability. While it's a plus what really makes the camera stand out for me, is the dynamic range. With the long star trail shot, it's Pulled about 4 stops. It was taken with an 85mm lens.

The other one, taken with the DA12-24 with my house peak in the shot is pretty much as shot. The 78 minute shot by the way was taken from the window shown in the second photo.

If I got out into an area where there wasn't so much light pollution, and had a tracking device, I have no doubt could do a lot more with it.

Thank you very much for information!
I live on the countryside so I think light pollution shouldn't be a big problem at here. I better start saving up for the K-5 and a good lens!
