Even with a really good 5-6" scope, you'd better have dark skies and a handful of expensive filters (hydrogen a, hydrogen b, oxygen III, at the least, each about a hundredish dollars) Also plan on good eyepieces.<br /><br />My NexStar 5 (very good optics) under less than ideal skies (euphemism) can show me the Orion Nebula in grays with a hint of blues. The snowball with a hint of blue. But most other nebula are well out of its reach.<br /><br />The 10" is another story...<br /><br /><br />If nebula observing is your prime goal, I second the Dobsonian. My choice, under decent skies, would be the Orion XT12 ($999 without computer, $1119 with). The 10" is a good pricepoint though, the XT10 is $669 without computer, $789 with. If you get the Intelliscope line, you can always upgrade with the computer add-on later.<br /><br />If your skies are good, it's all about aperture (and decent eyepieces). <div class="Discussion_UserSignature"> <p>.</p><p><font size="3">bipartisan</font> (<span style="color:blue" class="pointer"><span class="pron"><font face="Lucida Sans Unicode" size="2">bī-pär'tĭ-zən, -sən</font></span></span>) [Adj.] Maintaining the ability to blame republications when your stimulus plan proves to be a devastating failure.</p><p><strong><font color="#ff0000"><font color="#ff0000">IMPE</font><font color="#c0c0c0">ACH</font> <font color="#0000ff"><font color="#c0c0c0">O</font>BAMA</font>!</font></strong></p> </div>
