ghosting
After taking some pics tonight I noticed during processing there was some blurring of the image, almost like ghosting. It may well be collimation - I didn't check before taking images (in a rush...), having done a daylight collimation yesterday.
I'll make sure I do a star test before the next session, but in the meantime I'm just wondering if this ghosting is a symptom of poor seeing? It's more noticeable in the Saturn pic...
Cheers
Stephen
