					<description><![CDATA[<p>The TS 70mm f6.78 Quad is a great travel telescope for photographers and observers. The corrector is built into the OTA, so you just focus and you're automatically at the optimal distance. The TSED70Q has a comfortable working distance of 135mm from the 2" end, so you can easily use 2" star diagonals and eyepieces and still reach focus.</p>

										<content:encoded><![CDATA[<p>TS 70mm f6.78 Quad, 4 element ED refractor with built in field corrector, for imaging and observation<br />
Fully corrected and illuminated field is 32mm diameter &#8211; ideal for APS-C DSLR cameras</p>
<p>TheTS 70mm f6.78 Quad is part of the Imaging Star Line and an ideal travel telescope for all photographers.</p>
<p>The Apo is very well corrected for imaging and also offers good visual performance.</p>
<p><span class="goog-text-highlight">Magnifications up to 150x are handled very well by the ED lens, chromatic aberration is significantly reduced. </span><span class="goog-text-highlight">This TS 70mm f6.78 Quad is recommended for all nature observers, photographers and amateur astronomers who are looking for a compact telescope that does everything well.</span></p>
<p>The length of only 30cm (with retracted dew cap) makes the Apo very easy to transport in its case.</p>
<p>&nbsp;</p>
<p><strong>Advantages of the TS Imaging Star 70mm ED quadruplet:</strong></p>
<p>&#8211; very good field correction with the built in 2 element corrector<br />
&#8211; camera sensors up to 32mm diagonal are covered<br />
&#8211; 2 &#8220;dual speed Crayford allows photography and observation<br />
&#8211; 360 ° rotation of the drawer for the image positioning<br />
&#8211; flexible multifunction connection plate for direct attachment to camera tripods and mounts<br />
&#8211; Well corrected doublet lens with two special glasses (1x lanthanum) for a clear contrasty image</p>
<p>&nbsp;</p>
<p><strong>Two inch Crayford focuser with 1:10 micro reduction</strong></p>
<p>The 2 &#8220;Crayford keeps even heavy accessories secure by using reinforced ball bearings It guarantees a very precise adjustment with 1:10 micro reduction. If you have focus set accurately you can fix the position with a knurled screw. Long exposure times are possible without adjusting focus.</p>
<p>&nbsp;</p>
<p><strong>Imaging with the TS 70mm f6.78 Quad:</strong></p>
<p>Just connect your DSLR or CCD camera through a 2 &#8220;focal adapter or via the M48 screw adapter.</p>
<p>&nbsp;</p>

<p>&nbsp;</p>
<p>&nbsp;</p>
<p>This Apo is  optimized for imaging, but it also offers very good performance for visual observation.</p>
<p><span style="font-size: small;">The focal position allows the use of 1.25 &#8220;diagonals or Amici prism for erecting the image. </span></p>
<p><span style="font-size: small;">You can get, eg with a 32mm Super Plössl, a gigantic field of view of 3.5 ° at only 14x magnification. </span></p>
<p><span style="font-size: small;">You have the perfect overview.</span></p>
<p><span style="font-size: small;">With a 3mm Planetary eyepiece you get 148x magnification and can observe details on the moon and planets very well. </span></p>
<p>&nbsp;</p>
