Intes Micro 503 with great optics, certified 1/6 wave and I believe it. Very sharp in-focus diffraction patterns, identical intra- and extra-focal diffraction patterns. Very contrasty images due among other things to series of knife edge baffles lining the tube. Comes with Intes Micro thread-on 1.25" mirror diagonal, 0.6x large aperture focal reducer, 2.4x barlow, 15mm 55 degree field Intes Micro eyepiece, piggy back camera adapter (removable) and removable Intes Micro finder (its dew shild is baffled). Gives excellent views of the moon and planets. Coatings on mirrors and lens in fine shape. No dings in tube. Rear thread takes SCT accessories. Carrying case, instructions and optical certification included. Caps for OTA and finder. Please note that the photo tripod is not included.
If you are thinking of purchasing a Chinese Mak-Cass, you ought to look at this one.
Thanks for looking,
