I'm glad they've helped. That a good idea turning the plastic caps. I'd be interested in any differences. I'm imagining it will be something similar to what Orion and I were posting in his mask thread.
I've got a couple of other designs in mind to try so I'll do a bit of construction next weekend, and hope for some clear skies after that. I want to try to remove that last bit of unsurity through focus. The design may be restricted or work best with fairly bright stars but I think I can do it.. I'll certainly post how I go.

I'm kicking myself at the moment. I deleted the Avies and stills processed from them of those first tests I did. (desperately needed space on my HDD and didn't think I'd need them again.) I'll just have to redo them for comparisons and for

Mikes review. I should have known. First rule of Astrophotography: Don't throw anything out. You never know when you'll need it.
