Help needed
I seem to get colour abberations in my images like the one in this image.
It seems to be in the same direction regardless of the camera orientation to the scope or actual position, so I am not sure about the cause being telescope optics? My collimation was very good.
My set up in this image:
SCT 9.25" with f/6.3 reducer. Canon CDS 60d at -13C
about 80 x 30sec subs stacked with DSS and processed with photoshop.
At one stage I suspected that my corrector plate is out of alignment - but the orientation of the abberation would change with camera rotation.
Does anyone have any ideas what it could be and how to fix it??
Regards,
Tony.
