Hi M,
As long as your collimation is accurate, this is important in any scope especially anything F5 and below.
The E/P's that you're using sound like the culprits.
These are more suited to scopes with F stops of 6 and above.
If you are able to use another set of good quality e/p's you will see a difference.
BTW where are you situated?
Cheers, John.
