50 Minutes Of Venus
Posted By: Nitrok, 02-12-2009, 09:29 AM

Wasn't sure at first should i post this or not but decided to show what an 50min exposure taken with K10D looks like.
As you can see the noise levels are getting quite high even at ISO100 and the corners are a bit purple because sensor is getting warmer.

Noise does not bother me at all, I like how the sky turned out! Venus looks like a sharp scratch, though

Actually it is very good result with one 50 minute exposure. Even at ISO100 i would have expected much more noise or even a failure (ton of hot pixels, false or actual battery depleted) of some sort, as with my k100ds.
Was it taken with noise reduction on (50+50 minutes)?
It is fantastic how you got the sky and overall scene exposed so good with such a long/random time.
Is it more after the sunset or before sunrise? Was there a moon (does not looks like)?
Cool shot!

Thank you Georg! Venus is so bright right now so it really stands out.

Thanks ytterbium! Yes i forgot to turn off the noise reduction so it was 50+50.
I had to add a bit more exposure in Lightroom so maybe it affects also on the noise levels. I did couple of test exposures with higher iso settings and tried to calculate right settings and time for this one.
I started the exposure about an hour after the sunset. The moon was not visible at the time i took this photo.

Yes! Venus will be in its brightest nicely just on Valentine's Day this Saturday (Feb 14 2009)! Everyone interested to shoot Venus go get out next Saturday!

Which lens did you use, btw, the "scratch-like" appearance is due to those extremely sharp edges in its path, amazing!

Thanks for the info! I hope the sky is clear at Saturday.
I used Sigma 10-20mm @ 10mm.

Should have guessed! I hold my Sigma as one of the sharpest lenses I have!

Thanks Dan!
Drinking couple cups of hot coffee and watching starry sky. Time goes faster when you are doing something meanwhile camera takes the photo.
