Maybe I just needed a darker sky.  |
mmmmmmmm.......I understand but mistakes can be made even by sellers. It's a possibility that they slipped you the wrong one (by accident of course).
From what I've seen the photographic ones are more expensive, so you may have received more than you bargained for.
All things mentioned in this thread are valid. Light pollution, eyepiece used, eye condition, OIII filter and scope type etc...all these factors may or may not contribute to your situation. It may also be the case that all these factors are contributing to your situation. At least now you have something to go on. Good luck with it and hope you get it sorted out.
Please let us know how it turns out.
