Eyepiece projection is a method of capturing images through a telescope\u2019s eyepiece<\/a> using a camera with its lens removed, and is normally used where high magnification is required, for example when photographing the planets<\/a> or features on the Moon.<\/p>\n

One of the issues associated with this method of astrophotography<\/a> is attaching the camera adequately to the telescope, ensuring that it is accurately aligned with the eyepiece.<\/p>\n

There are several mounting systems that clamp onto the eyepiece body, but some eyepieces have a suitable thread built into their top to take an adaptor to produce a very solid and perfectly aligned threaded attachment point.<\/p>\n

The Baader Hyperion zoom lens has such a thread and would be a good choice. However, this method of photography can be quite fiddly.<\/p>\n

You would probably achieve better results using a high quality 3x Barlow lens<\/a> like the Explore Scientific 3x Focal Extender, Celestron X-CEL LX 3x Barlow or a Televue 2.5x Powermate.<\/p>\n
