    As it happens, Patrick Moore is on Sky at Night right now, advising to either start with a pair of binoculars or go straight to a phat telescope.

    Er. Fat. A big fat telescope that does everything. Moore was saying either go cheap and practical, or get the best you can afford.

    I don't think there's anything condescending about binos either - you can see a lot through them and they're much less of a faff. Something you can just stick in your rucksack wherever.

    How much do you want to spend?

    I just sat in my back garden and watched 16 satellites go over in the course of about an hour. Maybe 17 if the ISS was due to go over tonight. I've never seen even one satellite before, but I was wearing my glasses which I only got fairly recently.

    I've got a fat telescope too, but there are no planets round to take advantage of it.

    There's a poplar tree about 800m away, that if I put my phone camera up to the lens, the top of which looks like this, which is flipped annoyingly:

    I'll get some moon pics, cloud permitting.

    http://www.heavens-above.com/ is jolly good for telling you what satellites are going overhead. Put your location in (reg required) and it will tell you what's overhead. Some of the shit up there is interesting - especially the dodgy Russion stuff. Iridium satellites are nice and bright, 'cos they've got large polished panels which catch the sun.

    I've had my scope out just once all fucking 'summer'.

    I use SkyMap, you point your phone at the sky and it tells you about everything you're pointed at.

    Satellites too? That'd be great. Maybe I should get with the times and dump the old Nokia.

    An international team of astronomers has caught a star in the act of devouring one of its planets. BD+48 740, a red giant they observed using the 9.2-meter Hobby-Eberly Telescope at the McDonald Observatory in Texas, appears to have the fumes of a scorched planet in its atmosphere. This is consistent with a rocky world, recently destroyed.

    Could the same thing happen to Earth?

    Yes indeed, says Alex Faszpaln, a member of the research team from Penn State University: "A similar fate may await the inner planets in our solar system when the sun becomes a red giant some five billion years from now."
    The monster.

    This is just brilliant - an idea to deflect asteroids from a (lengthy, I guess) collision course by using paint.

    Can some recommend me a telescope for a lay person? Cheers!

    I was looking about a month ago but got steered away in favour of some bins. Picked up a pair of Olympus DPSi 10x50 for 35 delivered and they're *superb*. Jupiter & moons are extremely clear and the light that the large lenses captures brings out a lot more detail in the sky than you might expect

    Failing that, a cheap starter option for a scope is to go for a cheap Dobsonian

    I follow this guy on twitter and iirc he recommends a telecsope that's ~120 or so

    Cheers Rhythm! You can see the the moons of Jupiter or was that just a typo? :o

    I was looking at this one:

    Any good? I'll take a look at the olympus one too!

    I have a Celestron, which I'm very happy with. They're great value for money IMO. Mine is entry-level and cost just over 100.

    Get a Celestron Astromaster 130 EQ. Or an equivalent Skywatcher.

    Can pick them up for 100 - 150 and are fantastic. Don't bother with the motorised version. Also check the astronomy forums and pick up some extra eyepieces second hand.

    Don't buy anything cheaper than this as it is just a waste. This scope will let you see the rings of saturn, sometimes even the Cassini division on a good night, mars, nebula, moons of Jupiter etc.

    Avoid.

    One thing with the scopes is you have to get a decent brand or you are getting a toy which is not worth anything. Go Celestron, Skywatcher or Meade .

    SW are a good brand, decent optics at affordable prices. You'll need a decent star-chart and a planisphere if you're going full manual.

    If you don't know what you're doing and money is no object, get a Meade LS. Automatic everything!

    Oh, and I probably wouldn't get a EQ mount as someone suggested above as a beginner. They're a pain in the arse to learn to use. Don't see much overall benefit of a non-motorised EQ, tbh either. If you're going EQ, get a motorised one.

    Not a typo, I can see the moons of Jupiter. You'd be amazed at what you can see with even pretty cheap equipment

    If you have the room and limited budget, I'd recommend going for the largest Dobsonian you can. Biggest light gatherer for the littlest money (relatively speaking).

    They do have a learning curve, but I'd say it's worth it. Being able to just turn on knob to keep uranus in sight* if the scope is north aligned rather than having the duel movement of an AZ mount makes it well worth the effort to learn. Especially when using higher magnifications and stuff is moving fast.

    Yeah, I agree. I have an EQ mount and a Dob, and for planetary work I would always use the EQ. However, it takes about 20 minutes of faffing to set up. As a beginner, you've got plenty of other things to worry about and multiple other learning curves to keep you occupied. It's just one more thing that may possibly lead to frustration and disillusionment and result in the scope being on ebay in a few months, unused.

    Following from Chopsen's post, check eBay for unused scopes ;-P

    Jessops have a half price deal on telescopes at the mo. I take it the Jessops own brand stuff is garbage?

    LB, you really are a massive geek.
