    Micro-guttering for observatory roof?

    Cable trunking could work, although its mostly white

    Tripod for SW-SA

    I've tried a couple of different tripods with the star adventurer, and conclude that the best one is the one on FLO from sky watcher, here main difference is the central brace of the legs which helps a lot with stability cheers Mike

    Practical Astro show.

    looks good, one glaring omission from the exhibitors, is it too far from Exeter?
  4. lower temperature, no damage will result,
  5. Hi Andy that will be a really nice setup, many people would 'progress' to that on their 2nd generation of equipment. However, I would like to throw a couple of comments out for your consideration: Visually, the 80mm is ok but nothing spectacular, as the light gathering will be limited by the aperture. Photographically, it's a great setup, especially with the 0.87 reducer, even if F6.6 is not the 'fastest'. But it will be easy to get going, reliable and not need things like collimation, so an added bonus. In summary, like many things, it's a compromise that edges toward imaging rather than visual, but if that's what you're after, its spot on with great quality components Mike

    i have a relatively cheap one, i needed to collimate that first, so it needs to have adjustment screws, but then relatively easy to do, and only needed once (so far). the better ones, such as Howie Glatter, have a better focus or pattern of the laser which helps also. Catseye are superb but out of my range. in summary, cheap one is ok, but you should compliment it with a cheshire (or even just use the cheshire..), although i prefer to have both to hand

    http://www.astro-baby.com/astrobaby/help/collimation-guide-newtonian-reflector/ start with that problem with the laser is that it doesn't sort out the secondary mirror, (at least it can still allow errors in that part of the optical train), so a collimation cap or cheshire would be a good addition for you also..

    What`s your favourite constellation?

    Split decision for me, Corona Borealis as the one i remember from star gazing as a child, but Ursa Major and Orion for all their riches of different object types

    Pier height recommendations

    Apart from the visual/imaging consideration, and the longer term reflector/refractor consideration (looking into the top or bottom!), I measured the height of my AZEQ6 for the pier height, and reduced it a bit as i always needed a step up for viewing anything close to zenith. i've just been out and measured it again its 27" or 700mm from ground to top of pier plate, which is good for my 250pds, although for visual, 75mm less would have been better.

    New Toy for Imagers

    yes Trevor does a great job, his enthusiasm and 'old school' approach is really appreciated by me and many others. He dedicates a lot of time to this and his blog. This, in particular, is a great review especially as he says 'I didn't even read the manual and still set it up to guide and image from my tablet!' good call sunshine 4
  15. Personally, i find leaving a 10 sec delay between exposures sufficient for the temp to stabilise at about 5 deg above ambient (which will be pretty cold for you soon anyway ). i know this because on a canon, APT records the exif temp with each frame. i agree with you any more time delay is wasted time in my view. in fact, these days i use dithering rather than dark frames with good results, hope that helps, of course, there will be other opinions Mike
