    Thanks for the link - that's a helpful summary of the influence of the spider on diffraction. Ed

    Secondary mirror size?

    Hi - this should give you all the parameters: http://stellafane.org/tm/newt-web/newt-web.html It's a very interesting site, that calculates all the maths for newts. Ed

    Adjustable Observing Chair

    Good piece of work. I'm thinking of having a crack at something like this. They had a good project like this in the recent S@N magazine.

    Dob mount altitude bearing material

    I got the teflon from ebay, a small piece was pretty cheap, and it cuts easily into squares with a knife or fine saw.

    Authorities switching off lights

    Just wait until the neighbours discover solar powered garden lights, mounted on top of the fence. No power bills, and they light up just as it goes dark and stay on all night. Great! I think they've sat out under the lights for a couple of nights this summer....Luckily the lights are not too bright, and an empty plant pot over the top blocks out unwanted light. LP has definitely got worse over the last couple of years as security lights etc have become much cheaper. Our street lights are still on as well. According the the Campaign for Dark Skies website, the more light at night, the greater the problem with crime. It doesn't work the other way round - i.e. darkness encourages crime, which is unfortunately the 'common sense' view.

    To take a scope or not

    Take the scope! The skies can be incredibly dark in Cornwall and on a good night you'll be amazed at what you can see. I've seen the tiny Leo triplet galaxies through an 80mm refractor (ST80). If you've got the space to take the scope, I don't think you'll be disappointed, weather permitting! Oh to be down there this week......But then again, sweeping through the Milky Way with binos at this time of year is a treat...... Ed

    180 Pro?

    I have the 150 Mak Pro - it's a great scope. I would probably only swap it for a 180! I love it for double stars, planets, lunar, and dsos like planetary nebula. Ed
