I think I will go with that Bob. I sometimes barlow my 11mm on good nights ( we have pretty dark sky here and sometimes very clear) and get pretty good view at 218× especially planets. My old Parks (about 23yrs) still got it! But I guess ideally 140 to 150× would be ideal for my scope and my preference to view mainly planets, plan neb and brighter galaxies, and globs.
As for clubs none within cooee but did go to last SV astrocamp for a look (about 400ks) and really enjoyed it. If shift work allows will try to go again. Thanks again, cheers Richard
