The RC optical design delivers coma, spherical and chromatic aberration free results, perfect for color or monochrome imaging. A fixed position primary mirror eliminates image shift that occurs from focusing with other telescope designs. The iOptron RC6 comes with a 2" dual-speed Crayford focuser. Three focuser extension rings are provided for a &ldquo;flex-free&rdquo; solid extension as a means to take up any unneeded back focus. Its steel tube is equipped with knife edge baffles to diminish contrast reducing stray light, improving the instrument in both visual and imaging uses. A RC6 model comes with a Vixen style dovetail plates.</span></div> </td> </tr> </tbody> </table> </td> <td style="font-size: 13px;" valign="middle" width="1"><img src="http://www.ioptron.com/v/vspfiles/templates/192/images/clear1x1.gif" alt="" width="1" height="1" /></td> </tr> </tbody> </table> <div id="ProductDetail_ProductDetails_div2" style="color: #585858;"> <table class="colors_descriptionbox" border="0" width="100%" cellspacing="0" cellpadding="0"> <tbody> <tr> <td style="font-size: 13px;" valign="bottom" width="1"><img src="http://www.ioptron.com/v/vspfiles/templates/192/images/DBox_Border_Left_Bottom.gif" alt="" /></td> <td style="font-size: 13px;" valign="top" width="100%"><img src="http://www.ioptron.com/v/vspfiles/templates/192/images/clear1x1.gif" alt="" width="1" height="1" /></td> <td style="font-size: 13px;" align="left" valign="bottom" width="1"><img src="http://www.ioptron.com/v/vspfiles/templates/192/images/DBox_Border_Right_Bottom.gif" alt="" /></td> </tr> <tr> <td style="font-size: 13px;" align="left" valign="top" width="1"><img src="http://www.ioptron.com/v/vspfiles/templates/192/images/DBox_Border_Left_MidDiv.gif" alt="" /></td> <td style="font-size: 13px;" valign="top" width="100%"><img src="http://www.ioptron.com/v/vspfiles/templates/192/images/clear1x1.gif" alt="" width="1" height="1" /></td> <td style="font-size: 13px;" align="left" valign="top" width="1"><img src="http://www.ioptron.com/v/vspfiles/templates/192/images/DBox_Border_Right_MidDiv.gif" alt="" /></td> </tr> <tr> <td style="font-size: 13px;" valign="middle" width="1"><img src="http://www.ioptron.com/v/vspfiles/templates/192/images/clear1x1.gif" alt="" width="1" height="1" /></td> <td style="font-size: 13px;" valign="top" width="100%"> <table border="0" width="100%" cellspacing="0" cellpadding="0"> <tbody> <tr> <td style="color: #585858; font-size: 13px;"><strong>Features</strong><br /> <ul> <li>Coma free, chromatic aberration-free, spherical aberration-free optics</li> <li>150mm (6") optical aperture</li> <li>1370mm focal length</li> <li>f/9 focal ratio</li> <li>Fixed primary</li> <li>Low thermal expansion quartz mirrors</li> <li>Multiple knife-edge baffle system</li> <li>2" dual-speed Crayford focuser</li> <li>Finder scope base and dovetails bar</li> <li>Optional finder scope, diagonal and 1.25" eyepiece</li> <li>Optional iOptron Electric Focuser (#8451)</li> </ul> <br /><strong>Package includes</strong><br /><strong>#6111</strong>&nbsp;6" RC OTA only<br /> <ul> <li>OTA w/2" dual speed Crayford focuser</li> <li>2X25mm, 1X 50mm focus extention</li> <li>1.25" accessory adapter</li> <li>Vixen dovetail bar</li> </ul> <table border="0" width="100%" cellspacing="0" cellpadding="0"> <tbody> <tr> <td> <div id="ProductDetail_TechSpecs_div"> <table style="color: #000000;" border="1" cellspacing="0" cellpadding="0"> <tbody> <tr> <td align="right" width="206">Optical Design</td> <td align="center" width="396">Ritchey-Chretien</td> </tr> <tr> <td align="right">Clear Aperture</td> <td align="center">150mm</td> </tr> <tr> <td align="right">Focal Length</td> <td align="center">1370mm</td> </tr> <tr> <td align="right">Focal Ratio</td> <td align="center">f/9</td> </tr> <tr> <td align="right">Resolving Power</td> <td align="center">0.76 arc seconds</td> </tr> <tr> <td align="right">Limiting Magnitude</td> <td align="center">13.6</td> </tr> <tr> <td align="right">Highest Useful Magnification</td> <td align="center">180X</td> </tr> <tr> <td align="right">Secondary Mirror Size</td> <td align="center">67mm</td> </tr> <tr> <td align="right">Focuser</td> <td align="center">10:1 Crayford dual-speed</td> </tr> <tr> <td align="right">Focuser size</td> <td align="center">2&rdquo;</td> </tr> <tr> <td align="right">Dovetail Bar</td> <td align="center">Vixen-style</td> </tr> <tr> <td align="right">Finderscope Base</td> <td align="center">Yes</td> </tr> <tr> <td align="right">Finder scope</td> <td align="center">Optional</td> </tr> <tr> <td align="right">Tube material</td> <td align="center">Steel</td> </tr> <tr> <td align="right">Tube Length</td> <td align="center">19.1&rdquo;</td> </tr> <tr> <td align="right">Tube Weight</td> <td align="center">12 lbs</td> </tr> <tr> <td align="right">Other Accessories</td> <td align="center">2&rdquo; to 1.25&rdquo; compression ring adapter;&nbsp;<br />1" long extension tube X2&nbsp;<br />2" long extension tube X1</td> </tr> <tr> <td align="right">Gross Weight</td> <td align="center">18 lbs</td> </tr> <tr> <td align="right">Warranty</td> <td align="center">One year limited</td> </tr> </tbody> </table> </div> </td> </tr> </tbody> </table> </td> </tr> </tbody> </table> </td> </tr> </tbody> </table> </div>
