Am I right in saying that the higher focal length eye prices are good for deep space, and the lower for planets?
On the subject of purchasing new pieces, I'd really prefer to only have a max of 4 eye pieces or ill end up spending all night changing them around haha.
At the moment I've got a 25mm plossl, 10mm plossl and a 12.5mm unknown brand (but is marked with an H).
I imagine my next step would be a 2x Barlow and probably something 4mm and under?
Any suggestions on what I should purchase/ read up on, I'd really appreciate it.
Thanks for spending your time on a rather long thread,
Andrew

That 25mm plossl is actually a good eyepiece. But I know how you're feeling, you've got the 10" Dob and now you want to maximise

Go hard and buy whatever you can afford, the TMBs and the GSOs will put you on the right path without breaking the bank, go on, you know you want to...
