Amateur Astronomer Bruce Berger Talks About Meteors and Telescopes (Video) 36

Bruce Berger is an IT guy, but he's also an amateur astronomer who takes at least one aspect of astronomy more seriously than most sky-watchers. Not content with what he could buy when he first wanted a telescope of his own, Berger set out to make one -- it turned out so well, he says he'll never part with it, and he's made several others since, and taught many other people to do the same. In this pursuit, he's also been a long-time member of the Amateur Telescope Makers of Boston, including a stint as the group's president. (Berger's custom license plate reads "SCPMKR.") In the video below, though, I caught up with him in Maine between evenings watching this year's spectacular Perseid showers (and without any of his home-built scopes to hand), to give some insight about what would-be skywatchers should consider in looking at scopes. It's surprising just how good today's telescopes are for the money, but it's easy to be ripped off, too, or at least disappointed. (And besides avoiding department store junk, building your own is still Bruce's strongest advice.) Ed note: This Video is Part 1 of 2. Part 2 will run tomorrow.

    • I figured they meant Perseid.

    • Leonids happens in November (15th-20th to be exact).
      Perseid peeked a few days ago.
    • Yea, my thought exactly. Us amateurs have to wait until November for them. But I'm really not sure if they got the name wrong, or if this is just very dated and "this year's" refers to something that happened last year. Sloppy reporting either way, makes me not trust anything else that it might say.

      I've had two telescopes, not including binoculars and cheapo dime-store stuff. My first scope was 4 1/4" f10 Newtonian. Bulky to haul out with the steel mount, but a lot of fun. I was enthusiastic enough in my teens to haul it out when there was snow on the ground. Cold Winter nights had the clearest air in Northern Virginia, even if you didn't have the spectacle of the Summer Milky Way.

      When I went to school I traded it in for the compact backpack scope that Edmund was selling at the time. This baby wa

      I hate to put it this way but most would-be astronomy buffs would be seriously turned off by a Dob. Most people expect much more out of a scope to begin with without all the pains of being a Dob owner. I say this as the proud owner of a 12 inch Meade Lightbridge.

    So... what does his license plate mean? I assume it's related to being in the ATMoB since the snippet comes right after, but what's the [SCP]-Maker supposed to mean?

    He makes Special Containment Procedures to Secure, Contain and Protect makers?

    I think I'll just buy a Meade scope with the autostar system. Sure it's more expensive, but it's a whole lot less work for someone like me who just wants to gaze occasionally. I've got a little Bausch and Laumb SCT that I bought at a pawn shop for about $200 when I was in college. Equatorial mount but a real PAIN to align. The modern scopes with GPS and auto-alignment are a breeze.

    I was really hoping he was going to talk about building your own telescope and grinding your own lens.

    • by timothy (36799) Works for Slashdot

      Other years, Berger told me, he's brought materials to camp to demo the lens grinding process, but this year brought only ready-made stuff -- only so much fits in the Prius at once ;) I hope I'll get a demo of the grinding / design process later on, though. In the meantime, there's a lot of good info at the ATMOB site linked in the summary.

       

    • Some amateurs do grind their own mirrors, but lens grinding is a whole different kettle of fish. Hardly anyone does that. A little Googling will soon get you started with mirror grinding.

    For those that are interested here is a little more info. As you may know, the larger the diameter of the telescope, the more light gathering power it has. Similar to a bucket catching rain, the wider the bucket the more it catches.

    Refractors have two main disadvantages, one, the larger the aperture, the thicker the lens has to be as well, making the lense heavy. IIRC it also requires longer and longer tubes to focus the light.

    A reflector mirror on the other hand can be much shorter for the aperture size and the mirror can be lighter than a similarly sized lens, as it only needs to be a reflective film or coating on a lighter substrate, as long as it has minimal imperfections.

    Really good and large mirrors are expensive though. Here is a place that will sell you good mirrors if you want to make your own. http://zambutomirrors.com/mirrors.html [zambutomirrors.com]

      Very true, but at the same time, while "size matters" is true in astronomy, I also often see amateur astronomers fall for this thing and think that they should invest in a large "first scope", often with a large aperture. Most of the times these are Newtons, sometimes if money ain't a problem even larger Schmidt-Cassegrains.

      While with the SCs the problem is not that important as nearly all of them have the same aperture of f/10, with faster newtons people often are sold a large telescope because it is ea

      While size matters, the way the telescope is used matters even more.

      The last Astronomy party I attended featured a spectacular 28" Dobsonian scope built by a company called poetically "Size Does Matter". The Eastern Veil looked great through it. I then went back to my small 8" Schmidt-Cassegrain bolted a camera to the back, pointed it to the Eastern Veil and took a 2 hour photo that looks much better than anything I could see through the telescope 10 times the cost of mine.

      My suggestion to anyone who wants

    • Zambuto makes very expensive, high end, mirrors. Most beginners would be far better off spending $500 on a complete telescope from http://www.telescope.com/ [telescope.com]

    That barn in the background, is it covered with solar panels? LIke 200 of them? I'm getting ~20 panels on my house roof and it is expected to supply my annually-integrated electrical consumption!

      Yes, that's a barn covered with solar panels. I meant to count 'em, but forgot -- don't think it's quite 200, but it's a whole lot.

      I talked this morning with one of the camp's owners, and he said of the installation (which has taken a few years to complete) "I wish we had a bigger roof ..." It's supplying something over half of the camp's electricity needs, but not all. There are also solar heaters for water on some of the cabins, and generally they try to be efficient generally.

  • I'm an amateur astronomer. If you haven't seen the night sky from a really dark location then you owe it to yourself to do so. This map of the US shows you where's dark and where's not: http://www.jshine.net/astronomy/dark_sky/ [jshine.net] Basically, anywhere "blue" and darker will be breathtaking. You can go and just look up or bring binoculars and a simple star chart. You don't need fancy equipment to enjoy astronomy, but a dark sky is important.
