Trevor, yes the limb is still not perfect, a combination of the not-so-perfect seeing and processing I think. Also saturn is dim and this leads to under-exposure especially as I still insist on using 25fps :-)
I currently use a TV 5x powermate which has 4 lenses. I saw a cheapie 5x barlow on bintels site on Friday that has 3, I'm guessing it's a rebadged GSO 5x barlow (but thats a guess). I've read some reviews of the GSO 5x barlow that seemed pretty good so I've bought this 5x barlow and I'll compare it to the powermate.
cheers, Bird
