Orion StarBlast 4.5" Imaging Reflector Telescope Optical Tube

'

If you\'re looking for an exceptional telescope for astrophotography that won\'t cost you big bucks, then check out this affordable alternative. We\'ve optimized the optics of our popular short-focal-length Orion StarBlast 4.5 Imaging Reflector Optical Tube to give a fully illuminated field of view with the Orion StarShoot Deep-Space Imager and similar small-chip astronomical charge coupled device (CCD) cameras. The result is a compact imaging telescope with a price that will please the budget-conscious astrophotographer — beginner or expert — and with the performance that will give pricey refractors a run for their money.

With its big 4.5\" parabolic mirror and fast f/4 focal ratio, the Orion StarBlast 4.5 Imaging Reflector Optical Tube provides exquisite, high-quality images and it\'s simply the most affordable astrophotography-optimized telescope in the market. Unlike refractors, the Orion 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, we slightly widened the secondary mirror 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 charage coupled device (CCD) cameras. While the telescope works with standard 1.25\" eyepieces (Sirius Plossl recommended) some wide-field telescope eyepieces may require the use of an extension tube to reach focus.

At only 3.7 lbs, the StarBlast 4.5 doesn\'t require a heavy mount and it transports easily to your favorite site. The 1.25\" focuser accepts 1.25\" telescope eyepieces for visual use as well.

The Orion StarBlast 4.5 Imaging Reflector Optical Tube is offered as tube assembly only, with no accessories.
