Recently acquired a SSAG but noticed while using it with PHD during the clibration phase that E/W movements took place on the vertical bar with East at the top and N/S on the horizontal bar North to the left.

Although guiding went fine it was a bit disconcerting that the directions disagreed with the EQ-ASCOM controls.

Is this normal or do you re-orient the camera body for general use?

I don't worry about the SSAG orientation. One of my experiment was to make several tries at 45* increments (yes this led to some odd orientations) to see if it made any difference in tracking results, 'no difference noted'. You can try this to verify.

Hi Counterweight,

Thanks for your response which is more than adequate. Just want to make sure it didn't matter since I only used it for one short session. It replaced another imaging camera which operated just the opposite.

To make it easier to drift align with the SSAG and PHD, I orient my SSAG to fit the Y and X with Dec and Ra. For reference, this means that the label on the back of the camera is "vertical".
