Thanks for your replies. It's helped to straighten out my thinking abit.
Patrick,
Yes now that you mention it, it doesn't really make sense to get too worried about deep sky on the meade. A 2 inch filter on the dob will be how I'll use it. I might have been thinking about how I like to mount the meade on the star adventurer for the RA tracking but that's only really an issue on planets. In general I have some work to do on the dob to refine the alt az performance.
Thanks you both for the idea of the ES 30mm - I did a real quick google on it and it seems that it's a pretty good contender and I'm keen to limit what I spend if I can. I like value for money
I'd prefer to buy pre-loved gear abut I suppose these more premium eye pieces are a bit like heirloom items and people usually only part with them if forced to. I'll put a post in trade wanted anyway in case.
So i think I'm heading for a baader zoom with matching 2x barlow + ES 30mm and a UHC (prob astronomik). Now off to the bank manager
Thanks
Dave
