Camera orientation in push to.

[Keith Hewitt]

I've have a manual eq5 mount with RA motor. I have successfully imaged over several nights, matching the position carefully with push to, and guessing the orientation of the camera. However, recently I decided to use the new camera orientation feature on push to. I plate solved an image from a previous night to get the orientation (on the trifid nebula) of 82° E of N. I then polar aligned and manually rotated the camera to this orientation. When I got to the trifid nebula again, I expected the orientation to be correct and match the previous night. It didn't seem to, I used the ghosted image feature as always. Can anybody explain this? I'm sure I'm missing something obvious.

Hi,

the only 'obvious' thing would be if you are/were using the flip function of the camera on one of the captures but not on the other - that could upset the matching up of the orientations. Otherwise the value is calculated the same way for the image from the previous day as it is for the image when you are pushing to, so it should be fine.

How far out do you find yourself? That could provide a hint to what is going on (for instance if it is 180 degrees out)

cheers,
