Hi Hilmar

Is it so small as to make it useless to view objects that you mentioned in your reply. I know this is not the top-of-the-line, more like bottom-of-the-line telescope, but if the planets still look like fatter dots or the orion nebula still like a hazy dot (no addition to details I mean) as it does in the binoc.s then I don't know if it will perk up any more interest in my kid than he has right now.
Thanks for your response, in fact I felt like getting more costly one and sitting star-gazing myself :). Seriously I do like astronomy myself but have never got around to buying a telescope till now.
