Good value but not entirely compatible...
on September 12, 2011
This kit is good value for money and is significantly cheaper than buying the components individually. But... despite it being named `Astromaster Accessory kit' it is not fully compatible with all Astromaster scopes. One of the key pieces in this kit is the 2x Power lens. This 2x lens is mounted on a threaded Barlow tube which means that a T-mount ring can be attached to the tube and to that can then be attached an SLR camera. The problem occurs though if you are using an Astromaster 70mm refractor. The documentation that comes with the kit shows the doubling lens/Barlow tube nicely fitted into the focusing tube of an Astromaster 90mm refractor but unfortunately the focusing tube of the Astromaster 70mm refractor is too small for the diameter of the doubling lens (this may not be an issue with the Astromaster Reflectors as they have a different eye piece mount, though it is best to check first). Celestron Support suggest putting the doubling lens/Barlow tube into the `diagonal' (which may have some use for general viewing) though this then makes it impractical for land photography as the image is inconviniently inverted and, even more of a problem, because the camera is then effectively mounted on a lever at right angles to the focusing tube the eyepiece set screws cannot hold the weight of an SLR camera safely. Overall this kit is probably a good investment, the only weak point being the un-stated lack of compatibility with the Astromaster 70mm Refractor.
