Above image is first light through new Celestron EdgeHD 0.7
focal reducer. Also first use of Optec TCF-Si
temperature-controlled focuser. Image is cropped only by a
few pixels at right and top, to remove dithering effects.
For comparison to same object taken with Optec's Lepus 0.62
focal reducer (no TCF-Si), click
