The SFF60 Field Flattener for SV60 Apo Doublet is designed to rival the quality of more expensive telephoto lenses. With this dedicated flattener you can now expect to get the same performance as shown in the image below of the Heart Nebula below taken by astrophotographer Jon Talbot (using a Canon 60D camera). The 330 mm focal length of this telescope provides very wide field images using this flattener.
The SFF60 Field Flattener threads onto the SV60 focuser and works with a DSLR camera and t-ring. To mount, simply unthread the focuser's 2" adapter and thread this flattener in place. This flattener will improve the flatness of field of the SV60 when used with APS or smaller chips. If you are using a ccd camera you may need to add some t-thread extensions in order to reach 55 mm back focus spacing on your camera.
