  • I have seen the Geminids regularly and find them very impressive. I saw one when I was younger and I was hooked. So hooked I need to see more! I have luck with these. I can usually find a good clear night in December (nearly the longest nights of the year).
  • Ever been to a star party with nothing to see? Here you have 3 objects of different sizes (and phases) moving around over a week – easy to plan an event knowing that there are more days following where weather might not be an issue. Early evening too, so no late nights.
  • Interesting to see objects change their place in space over time, plus an opportunity to hone your photography skills – how do you get a bright moon and a dimmer planet in the same picture
  • Although this is all very interesting and I’m hopeful that it will be an awesome comet. It’s two months away and it still isn’t visible to the naked eye or binoculars – and might be visible for one or two days at most when it nears the Sun.
  • Although this is a very optimistic representation, there may be only a few days where we see it on the western horizon of the size of comet West.
  • Hone your photography skills – figure out what you want to get in the shot? 8 pm on Wednesday August 7
  • Sit outside, have a party
  • Hone your skills for the Mercury transit in 2016
  • Honing your site location choices, your photography skills
  • I don’t want to be fooled by a comet, but I’d like to prepare for a spectacular event. What parameters mark a good commet?
