  1. I've been looking at that, yeah, I believe they have a star camp coming up in the Autumn, I'm thinking about signing up for that - could be a blast. There is a little bit of LP around here, but I think there are loads of little tricks you can combine to reduce it down. I'll say one thing though, the night sky around here can be pretty spectacular. If you are on the military road looking for a place to observe from, turn right a bit past the Robin Hood pub and head towards Matfen. I wouldn't go into Matfen itself, but there are some nicely situated spots on the side of the roads around there which seem to have big skies and very little LP. Not much traffic either. Alan
  2. Will do, definitely. At the moment, I'm without a vehicle, so I'm tending to look for places within a reasonable walking distance of Corbridge - I figure I can come up with some sort of trolley arrangement for the gear, if I need to. Found a couple of what look to be nice spots, but I have a couple of weeks yet, so I'll keep looking around. Alan
  3. At school, personally, nothing. At home, right now, as we speak, I am still busting with pride because my five year old son just explained to me - with no prompting - that the reason we cant see the stars during the day is because the sun is so bright it turns the sky blue when its on "our side" of the planet. The reason I'm so proud? He's five. He's managed, with me answering his questions only, to put together a nearly (its an oblate spheroid) spherical earth, conceptualised an orbit, recognised that where he is isn't the totality of earth and still managed to be a five year old with a burning passion for a playstation 3 and a secret love of Thomas the Tank Engine. Personally, I think my wife and I have done something right there, but only time will truly tell. Whats really scary is that his three year old brother doesn't just outsmart the five year old, but his mother and myself most of the time as well. pride/respect/nervousness/fear/love Alan
  4. Slim, in about a fortnight, I'm expecting to have gone through the same process as you, bought my first proper telescope and doing some lonely astronomy on the roads between Newcastle and Carlisle. I'm based in Corbridge and have been scoping out some useful spots around here, I'll let you know how I go when I get my telescope - I'm looking at pretty much the same as you, either a 150P/200P or a Nexstar 127 will do the job.

    Hello all

    Wow, a warm welcome indeed, thank you very much!
  6. I believe aFOV is Apparant Field of View. Focal length as far as I'm aware is printed on the side of the eyepiece, field stop I'm not sure of. As far as the CCD section goes, that one is a complete blank to me at the moment, I just haven't had the time to do the research into it. I will though, being able to get an approximation of what I would see through these telescopes has been very useful, I imagine the ep and ccd sections will prove equally so. Alan
  7. I'm using an Android phone at the moment, with my really ancient 76mm Newtons, in concert with an app called SkEye. A lot of people are mounting their phones onto their telescopes and using the it as a kind of "push to" system. Basically works by using the sensors on the phone to get altitude and azimuth information, along with the GPS location. Works a treat. Alan
  8. Weird, wonder why it did that? You are running the latest version of Stellarium? Alan
  9. Thats what its supposed to do, the screen becomes ocular, then when you hit CTRL-O again, it goes back to normal. Alan
  10. Thanks for the response guys. You are right, its easy enough to do it inside Stellarium itself, but I found when I wanted to page through loads of websites looking for focal lengths and diameters and so on, editing the textfile was faster. Also, I use Stellarium on two computers, it saved time. Cheers, Alan

    Hello all

    Haha thanks guys, its posted already, in the beginners forum. Alan
  12. I originally posted this on another forum, but since I wrote it and came up with the modification, I figure I can post it here as well. I've been finding myself beset by that age old question "but what will I see through xxxx telescope?" Now, I played with Stellarium a long time ago, and since this opportunity first surfaced, I've been playing with it again and I've found there is indeed a way to get an idea of what things will look like in different telescopes, if you use one of the plugins which comes standard with Stellarium. The plugin is called Ocular, and is invoked by selecting a target (I chose Saturn), then pressing the CTRL-O button combination. What you should find is that your field of view shrings and your view suddenly resembles that of a really nice telescope which is far beyond a beginners scope. So, with that in mind, I went through the details of most of the telescopes which have crossed my shortlist at some point and created a file which will allow 18 of those telescopes to be simulated in Stellarium. Its simple stuff, its only text, but the file you need to copy this into is in a tricky part of the Windows filesystem to get to, because Microsoft tends to assume everyone is a yokel and hides a lot from you. So, if you want to try these 18 telescopes, open up Windows explorer and type the following into the location bar at the top, substituting "USERNAME" with your username on the computer. C:\Users\USERNAME\AppData\Roaming\Stellarium\modules\Oculars Linux users, I assume the file you are looking for is in the .stellarium directory of your home directory, but I could be wrong. Mac users, I'm afraid I have absolutely no clue how your operating system works. I think Steve Jobs kidnapped The Woz's pixies and has bribed them with beer, to be honest. Anyway, in that directory, you should find a file called "ocular.ini". Right click that file and choose to open in notepad. Once it is open, there should be a section called "General". In that section, find the line which says "telescope_count=4" and change the 4 to 18. Scroll down a little further, past the sections labelled "[bindings]" and "[oculars]" and you should find the section labelled "[telescope]". Highlight everything from the word "[telescope]" to the next section down, which is called "[ccd]" and press delete. After that, paste this text in its place.

Once you have a target selected, (as I said, I chose Saturn) press the key combination CTRL-O to invoke the plugin. Once you have done that, other key combinations will change telescopes and eyepieces. To change telescopes, use SHIFT-] to go up through the list and SHIFT-[ to come back down. To change eyepieces, use CTRL-] to go up and CTRL-[ to come down. If you press ALT-O, you should see a dialog open up, clicking the "About" tab on that dialogue will tell you more about the plugin. As soon as I've figured out what the abbreviations in the eyepieces section of the ini file mean, I'll add some standard eyepieces and digital cameras. When you are using this, remember that Stellarium, while fabulous, is still just a simulation. On Stellarium, every day has perfect seeing, or very close to it. This customisation should help get an idea of what things will look like, neither I or the creators of Stellarium can guarantee that what you see is what you get. Hope this is helpful, it certainly has been for me! Alan Edit: I've been trying to fix the bad formatting of the [telescope] text, but it wont let me. My blog has a repost of this on it, grab it from there if all else fails. Sorry bout that.

    Hello all

    I'm a bit of a newbie to amateur astronomy - dont yet have a telescope yet, but am expecting a little payout at the end of this month, which I'll partially use to grab myself one. I have been doing a fair bit of lurking here and posting occasionally on other forums, but decided to sign up here since a) these forums are more local and relevant to me and you guys seem a lot more relaxed than some other forums I've found. I'm suffering from the same troubles most newbies seem to be asking about finding new gear, but I've found a somewhat useful solution, which I'll post in the beginners forum rather than here. So, hello all, looking forward to a chat! Alan
