You can do some wonderful work with DSLR cameras. I've just posted a batch of images, one of which uses color data that I captured with my old 300D (The Andromeda Galaxy shot).
Do you have a wedge for your telescope? You'll be extremely limited without one as you will have field rotation on any significantly exposure length. -Jeff |

Rickj, would i need a wedge for my etx 125 ?, i noticed on TelescopeHouse, that there is a wedge for my scope priced at about £40.I finally got the scope up and running with the PC and got autostar updated etc..... i think myself that the pc cable was to long, it was 10metres, why do they sell them that length if they know themselves that it will degrade the signal, i plugged the 6ft cable in, and it worked straight away

For planetary imaging no as rotation of field isn't a problem with such short exposures. Nor for visual use is one needed.
For longer exposure deep sky photography you need to tilt it to your latitude and align to the pole to prevent rotation of the field. A wedge is a good way of doing this, though not the only one it is the easiest for most. Though I don't know of the drive is up to long exposures, I've never used one this way. Rick |
