Built-in Bahtinov Mask Dust Cover!

The GT 71 APO Telescope from William Optics comes standard with a dust cover that has a built-in, clear Bahtinov Mask for perfect focusing every time. Simply remove the flat front cover plate, leaving the dust cover cuff in place on the telescope. Point the telescope at a bright star, and focus carefully. When the bright central diffraction spike looks exactly centered between the other two spikes forming an "X", then your telescope is in exact focus for stars. Remove the dust cover cuff carefully from the objective end of the telescope, and you are ready to image.

Please Note:  We have included images of the Gold version of the GT71 due to the lack of photos of the Red Version.  The scope you will receive with this order is the popular White with Red Highlights.  See the first image to help you visualize the rest.  Thanks!
