Rotate image 180º

[Sergi]

Hi,

when the mount changes the meridian, the images rotate 180 degrees. Is there a way to rotate the image from BYEOS ?
I just downloaded the version 3.1.5

 

regards,

Yes, and no.

 

In Imaging mode, you can choose to rotate the displayed image, but the saved image is not rotated.  This is the way it must be. 

 

If the saved image were rotated, then your calibration software would have to know that in order to correctly apply calibration frames (master darks and flats would also have to be rotated before they could be applied).  If your stacking software does not automatically recognize a meridian flip occurred then you will have to de-rotate the post-flip images before aligning them.

Thanks Astroman133 . I think that pixinsight rotates images when stacking.

Yes it does

Deep Sky Stacker also rotates when stacking. I think that's a standard feature of any stacking program, to re align dithered and rotated images.

If anyone knows how to do automatic de-rotation in CCDStack 2, please let me know.  My scripts have a manual blink step to allow me to de-rotate images before aligning them.

 

Thanks,

I've never noticed a problem in CCDStack2, but then I just recently learned that iTelescope.net does auto meridian flips so I was avoiding meridian flips previously. Another possibility is that I also have ccdinspector, which adds some alignment capability to ccdstack, possibly including rotation.

 

I look for some rotated data to test.
