Originally posted by Erictator I am another viewer inspired to want to try some night shooting after seeing your work Patriot. I've tried my old Tokina 20-35mm in the past, w/ single 30 sec or less exp and it was fair. Thinking the FA31mm might do a better job, my other options are my Irix 15mm or Soligor 20mm ... but the FA is the fastest of the bunch and maybe the sharpest. Not sure how bad CA will be on stars? I'd love to try deep sky stuff, but as I understand it, the Astrotracker in the K-1 doesn't move enough for long lenses like my 150-450, and I don't have an Eq mount.

Eric for shooting the starry sky it is best to use a wide-angle lens like Irix with a 2.4 aperture is enough, with iso set to 1000-1500 and speed like 20-25 sek.
Another thing is the background, to get it in acceptable quality you need to set speed like 3-5 minutes.
So you need make two shots in the same positions, first for the sky and second for background and then to merge them in Photoshop.
All frames with a starry sky and with a well-drawn background are made in this way.
Many photographers shoot the background in the full moon, in good light, and then add the starry sky shot in the complete absence of the moon, when the stars are best seen.
Hope this helps
