Star Field

[Fotografer]

Greetings:</p>
<p>&nbsp;</p>
<p>It has been a while since I've dropped by. Hello again. </p>
<p>&nbsp;</p>
<p>I have been attempting to photograph star fields. But I think my first attempts are a bit crap. Can anyone give suggestions?</p>
<p>&nbsp;</p>
<p>I have a D90, use a tripod and remote, and no filters.</p>

<p>I'm looking forward to hearing your pointers. I am especially interested in hearing from D90 owners who has done this in the past.</p>
