Orion StarBlast 4.5" Imaging Reflector Optical Tube with Software

The Orion StarBlast 4.5 Imaging Reflector Optical Tube provides exquisite, high-quality images with its big 4.5" parabolic mirror and fast f/4 focal ratio. Unlike refractors, the StarBlast introduces no chromatic aberration with negligible coma. The fast focal ratio also minimizes exposure time and guiding errors. To achieve 100% illumination with the StarShoot Deep Space Imaging Camera, the secondary mirror is slightly widened and extended the focal point further out in the focuser.

The short focal length provides a wide field of view for imaging with small-chip CCD cameras. While the telescope works with standard 1.25" eyepieces (Sirius Plossl recommended) some wide-field eyepieces may require the use of an extension tube to reach focus. At only 3.7 lbs, the StarBlast doesn't require a heavy mount and it transports easily to your favorite site. The 1.25" focuser accepts 1.25" eyepieces for visual use as well.
