2-Inch Adapter

This adapter threads onto the T-ring on one side and the focuser of your telescope on the other.

IR/UV Blocking Filter, Coma Corrector (If Required):

If you are planning to take exposures with a refractor, you should consider buying a 2-inch UV/IR blocking filter (see page 22). If you are using a Newton telescope, you might have to employ a coma corrector in order to capture pinpoint stars all the way into the corners of your image (see page 107).

Budget

The table on the next page shows a sample purchase price including the camera body. All prices are reference values (June 2007); products from other manufacturers may vary in price. The calculation excludes the following items, assuming that they are already available: a telescope on an equatorial mount offering the capability to make fine adjustments; a guide scope with a reticle eyepiece; a computer with sufficient disk space, image processing software, and backup devices.
