G'day Mike,
Do you wear glasses? Do you care about eye relief (how far you have to place your eyeball from the top of the eye lens)? What is your approximate budget? In advance of the above information I'd suggest a secondhand Meade 5000 SWA 20mm ocular if you can find one. They aren't the very best option but they were pretty good and Meade sold a large number of them at reduced prices a year or so ago. Other options include the Panoptic 19mm (really nice but considerably more expensive), the Explore Scientific 68° 20mm (basically the same as the Meade above in a different casing), and several others. Give us a few more hints about your preferences and I'm sure you'll get plenty of replies.
Whatever you get, I imagine your skies are
far darker than mine!
