Thanks for that Allan. I hope to be watching on Friday night.
I saw Io disappear behind Jupiter a week or so ago, quite impressive. I find Jupiter so bright it may be hard to actually see Io as it transits but hopefully the shadow will stand out. That’s why Callisto seems a better proposition as it is much larger than Io. I'm still using the EPs that came with the scope so I may be battling to see detail using high mag.
Shaun, see this post by Allan, it's post No 12

You seem pleased with your Orion edge on planetary Shaun. I've been considering one of them as a replacement for the EPs that came with my scope. Difficult decisions to make
