  1. Page 22 of the Manual http://www.skywatcher.com/downloads/SynScan_HandControl_web_280313V3.pdf
  2. Orion is easily visible through binoculars, along with a few others. Dumbbell, Helix and Tarantula are also visible under dark skies. Andromeda and other bright galaxies are also visible. Star clusters, both open and globular, are ideal binocular targets.
  3. I've been using this app for the last 6 months. It's my most used astronomy app. Just fantastic.
  4. I should have qualified my statement better to start off with. I was talking merely with regards to reflectors. Most of the tabletop dobsonian reflectors have serious compromises. For example, you need a sturdy base for them. Some have limited collimation options. I just felt that whilst an 8" dob is the ideal reflector option, it's just that bit dearer than a 6", and if you buy a 6", I feel that the only compromise you have made is on aperture. The 6" is forgiving on collimation, while still remaining very sturdy, easy to align, easy to setup. It has that "wow" factor when people see it, which is always good. I'd love to have more experience with a good refractor, and I'm sure most of the affordable 50-70mm refrectors are perfectly usable, but they nearly all come with poor tripods and/or mounts. An AZ on a good tripod would be good, but a lot of them seem to come with those awful EQ-2 style mounts. I hope I've explained my opinions.
  5. Just buy a family membership to the local astro society, and have the use of many scopes available to you. If you absolutely have to buy a scope, I wouldn't settle for less than a 150/1200, the only compromise on that scope is that it isn't a 200/1200. Anything less has far too many compromises/
  6. I've been buying Astronomy, S&T, and Sky At Night for the last 12 months. Sky At Night is a very friendly, beginner oriented mag. S&T seems to me to focus on AP and strong science. For my money Astronomy provides a good balance. I've purchased a couple of issues of All About Space in the past, which is fine if you want to read about colonising other planets.
  7. Don't rush into collimation. Do a star test first. Even if it's a little off, it should still be good enough for visual use.
  8. It certainly won't be very useful. There is one of these in a local store. I'll have a look at it Thursday or Friday and see what I can make of it.
  9. Does the front flip over? With southern hemisphere printed on the back?
  10. For eyepieces on a budget, look at the 9mm "gold line" eyepiece to replace your 10mm. The 25mm should be good enough.
  11. They're a great design. I own the 10x50, and the locking focus and detent on the diopter adjustment sold me on them.
  12. Fantastic shots. I'm not really interested in astrophotography (I'm just not dedicated enough) but I'd be happy to capture images like this. I couldn't find details on your mount. Alt-Az or EQ?
  13. My son is the same age as your son. He too asked for a telescope for christmas (which is how I got into this whole caper). I decided to pool the money that we, my parents, and the in-laws would spend, and came up with AU$400 (~GBP190). I then did my research, and found that a 6" SkyWatcher dob fitted the bill. I made sure he understood the limitations and weaknesses of the scope. We went out to a Star Party at the local astro society, which only served to bolster our confidence over the decision. We haven't looked back. If you can find a second hand 6" (or 8") or can stretch the budget for a new one, I can highly recommend it. We have seen all the things on your checklist, and so much more.
  14. I'm not quite sure what you mean here. Stars are among the brightest objects in the night sky after (most of) the Solar System objects. What are you expecting to see?
  15. I was looking the other day, and there are a few 8" dobs on Gumtree. Only 1 in Vic, but quite a few on the east coast.
  16. There are proper shops in Adelaide, Melbourne, Sydney and Brisbane that I know of. You might benefit from taking the time and heading into one of them. Not sure about Perth or Darwin though. Also, have you considered attending a star party at your nearest Astro club.
  17. We have the 9mm. It is a measurable improvement over standard 10mm or 25mm eyepieces that come with most telescopes. I couldn't be 100% sure, but I feel as though they add a touch of colour (orange) to the views. I was certainly very impressed with ours, for the money.
  18. My son, who is "on the spectrum" got his first telescope when he was 12 (last Christmas). We bought him the SkyWatcher 150P (as a joint present from the whole family). I knew nothing about the night sky, so a I did a lot of reading, and just got outside whilst waiting for the scope to arrive. I guided him initially, but these days, I'm only out there to help him move the scope around! Which does raise the point of portability. He can move it from the inside to the outside on his own, but once it's assembled outside, he can't move it on it's own. Don't discount the option of a nice set of binoculars. They are excellent for panning around the night sky, and you can see loads. He will also be able to take them with him when you go out. He can look at birds, trains, boats, planes. And they are the sort of thing he will still have when he is much older. Feel free to PM me if you want to chat outside of this thread, but I would encourage you to ask tons of questions here.
  19. It turns out there is more than just Planck at that location https://en.wikipedia.org/wiki/Lissajous_orbit#Spacecraft_using_Lissajous_orbits
  20. The point in the shadow of the earth you are talking about, is called the L2 (2nd Lagrange Point). The Planck Telescope currently sits there, and soon the James Webb Space Telescope will sit there. http://sci.esa.int/planck/47365-fact-sheet/
  21. Stunning.... I'd love some more details on your setup.
  22. It would not be difficult or expensive to make a simple dob mount.
  23. With all due respect, how exactly would we know what you think it is?
