Hello all
This is a bit of continuation on from my collimation thread I posted earlier. (
http://www.iceinspace.com.au/forum/s...310#post302310)
Basically, after collimating the scope and taken it out for it's first light, I noticed unless I had my eye dead on in centre, there would be a "ghosting" effect on the object I am looking (e.g. I'd see saturn and then a fainter version next to it which would move relative to my eye placement).
I am using 8mm Orion Stratus, 13mm Hyperion and 21mm Hyperion (also tested with 20mm Bintel Plossl), and it happens with all eyepieces (less with the plossl).
Can anyone shed some light on the matter as to why this is so? Your help is greatly appreciated thankyou.
