thanks orion,
not sure what you mean by field rotation, if the image is being tracked, then are you saying that a object taking up the width of a image ie nebula etc will rotate around on the screen, some of it will be fixed, but maybe the outer edges will rotate?
whilst with a eq mount the whole image remains tracked and not rotating
ssshhh, don't tell asmiov about this advantage of the eq, we all had converted asimov to believing that dobs are the best and eq's are sh1t that it is much better to push it two directions than one!!!! now where is that little smiley guy with a stick? argh here it is...
