Don't forget the dark cloth to throw over their heads when looking through any solar telescope. I tried black plastic trash bags, but it gets too hot inside them. And you need several to stop the light. Dark cloth works best. And you need the right coated eyepiece to get the best view. Too low and you miss a lot. Too powerful and you lose detail, fast ! The view through a solar telescope in H- alpha generally wows anybody. The view through a 90mm solar telescope is shocking. So is the price, but the view is worth it. You still need to block out as much outside light as possible to appreciate the fine detail.
You might want to mention to them that The Economist has a Feb. 28 article in the 'Science & Technology' section entitled, 'A Comet Headed For Mars' about a comet that is going to do a Mars near miss during the fall of 2014. Too bad it won't be a near miss of Earth. Those Martian rovers are lucky, unless it hits. They estimate that a Mars hit could be seen from Earth, during the DAYLIGHT! Maybe a close pass to Earth wouldn't be such a great idea. It makes you wonder what would happen if one hit our Moon. Those robotic telescopes are finding a lot of stuff flying around out there. I mean really, what is the chance of a comet just missing Mars? Not much. Giant Jupiter sure, but Mars? Maybe I should have studied how that Mayan calendar works?
Does this cost money to enter?
@RDeCory, yes, it's $20 per day, or $35 for a two-day pass. You can purchase tickets online at rockland-astronomy-club.myshopify.com/.../neaf
