  1. I arrived home at 2am this morning with my teenage daughter. We both commented on how clear the sky was and that we could see Jupiter rising above the tall buildings that surround our tiny garden. I asked if she would like to see Jupiter through a scope and she said yes and then requested that we use the big scope (my 200p-EQ5). So we lugged the scope, mount and associated bits out into the garden and set up. She was suitably impressed with Jupiter and I was happy because I got to try out my new BST Explorer 5mm eyepiece. I thought I would push my luck so I asked if she wanted to see anyt

  2. Earlier this morning (a morning that had started like so many others - with thick, listless, orange clouds overhead) I was fortunate enough to be awake during a power cut - my first as a stargazer - that happened not long after the clouds had rolled away. It was a fairly localised outage, so the sky wasn't dramatically transformed, but it was lovely to be able to walk around by starlight alone, beneath a night sky untouched by that familiar sodium glow. It also got me outside just in time to see several incredible meteors tearing through Perseus and Taurus, with Taurus in particular looking sp

  3. Hi there, I decided to give a reprocess to my M31 image, I think I got lucky this time, it's a more agressive processing and the colors are better on this one, what do you think? I croped a bit on the lower part of the image to get rid of a darker band, I must redo my flats to see if i can cure this, Regards, Luís

  4. Myself and a couple of others from the Caithness Astronomy group,Gordon Mackie and Maciek Winiarczyk went out to Brough harbour on a pre aurora reccy.We reckoned this would make a great scene for a good aurora display.The bright glow on the horizon comes from the Flotta gas flare stack. The last shot shows a faint hint of aurora on the horizon to the left of the rock stack.Thinkit will make an impressive scene when a strong display comes our way.

  5. I was dozing at 4am this morning,when the wife said to me "look at that bright star!" Of course it was Venus,but, as I blearily looked out of our bedroom window,I had to admit that the sky view was fantastic! There was Jupiter,Taurus with the hyaides,Pleiades,Auriga with brillant Capella,and to top it all,Orion in all it's splendour! A marvellous foretaste of the winter skywatching season to come. Wished I'd tried to spot Mercury now.

  6. After not selling all my astro kit earlier in the year, it came real close!! I moved house and have now a new setup which is much more user friendly and an improved position regarding viewing area and light pollution. The living/dining room has a perfect place next to the rear patio doors for the "imaging control centre" with an outside air duct, just visible in the photo at the bottom left side, for the USB control cables to exit the house. So nice and warm and I can check what is going on with a turn of my head if I am watching TV or a movie. The roll off shed obsy can just be seen out of th

  7. Use limiting magnitude as your guide: the stars of Ursa Minor are particularly useful for this because they never set and are always at approximately the same altitude in the sky. Make a chart of the constellation and mark in the magnitudes using Stellarium or equivalent (go down to 6.5 or whatever you think your dark-site limit might be). In time you'll memorise particular stars that serve as indicators of sky quality. At my dark site I can have times when the Milky Way is brightly visible but by looking for familiar stars I can see that transparency is poor. Also note that at a dark site it

  9. Just returned from a few nights stay on the LLeyn Peninsula West Wales at a camp site in Uwchmynydd, what I saw was amazing even at my late age in life I can't honestly remember what the milky way looked like, and when I came out of my tent and looked up I just stared I wasn't even bothered to get my bins out their was so much to see and wonder at just with the naked eye, and that misty trail was awe inspiring. I was glad for my 12 year old daughter who is into astronomy for her to witness what she could only see in photos, and my 9 nine year old son who doesn't follow in his sisters footsteps

  10. Hi Guys Does anybody know where is the best place to get replacement CG5 slow motion control knobs? My young son decided in his wisdom to start messing with my telescope and now one of the knobs has the metal ring inside missing meaning it no longer fits! So far I have found this; http://www.harrisontelescopes.co.uk/acatalog/SkyWatcher_Slow_Motion_Cable_Set_EQ2_EQ5_AZ3.html Does anybody have any experience of using these? I want a like for like replacement but I can't find one online so I guess I would have to talk to Celestron/skywatcher if I did. However if these are better then I might as

  12. So I have been sketching sunspots since pretty much day one in this hobby of mine, that's 20+ years now. My sketches have never been about art (you'll see why below) but I do enjoy keeping a record of the number of spots I see and comparing what I see from day-to-day and week-to-week. Today's sketch is shown below. The document is one of several template docs I use for the purpose, depending on how busy the Sun is. I have recently started to photograph the Sun with my new DSLR but at this point in time I still see more detail visually than photographically. Here is a link to the photographic

  15. Hi, After watching nice blue skies all morning and too busy at work to give the sun a go, it clouds over in the afternoon. But wait what is this driving home, I need my sun glasses, yes it is the sun. Frustrated as I sit in a traffic jam, will I get home in time? By the time my PST was installed on my eq6 and aligned, the sun went behind cloud. Then just before it dipped below a neighbour's roof, 5 minutes of reasonably clear. I don't think I had the focus spot on, but pleased to have got the big prominance. 2300 frames, best 93% taken, around 750 frames with about the same for the prom.

  16. Here we go again,weeks of cloudy skies,not even a sniff of a clear sky.I,m normally an imager,and i always fail to get a complete run at one object in one night. Next time i see a really lovely image of a deep sky object,taken from say France/Spain/Greece,instead of saying wow thats fantastic,well done,im gonna say "Yeah Nice". Weather sites are woefull they constantly change hour to hour,and they never all agree anyway. Had to moan,as i check another weather site now. Sat24 is the best,but you know what that is going to look like. Ah well. Mick.

  17. Was up at 03:45 this morning and the sky was clear. I saw Orion, the Pleides and Taurus very clearly through my binoculars. It was like seeing old friends again and I was very excited. Jupiter and Venus looked beautiful and I can't wait to see them through my 'scope at a reasonable time of the night! I love astronomy!!

  23. Nice that you've got a reprieve Pete. Astronomers do get peeved off here in the UK. If it isn't the poor weather, it's light pollution, and we have an abundance of both unfortunately. Selling your gear wouldn't have eradicated your astronomy though. It never leaves you. Ron.

  26. That is the problem with this type of programme. It is no good saying Horizon has been 'dumbed down' or 'it isn't like the programmes they used to make', the problem is the Internet and access to Wikipedia and sites like this. Once apon a time if you were interested in a subject you subscribed to a journal, either one of the professional societies or one of the hobby mags. Articles for professional journals take up to 6 months or more to publish, not sure how long for a mag. Now everyone can post and keep up to date with events/discoveries in glorious colour the minute after they happen and

  28. Generally speaking, things are moving away from each other because the universe is expanding following the Big Bang (probably!). Imagine to dots drawn on the surface of a balloon; as the balloon is inflated the dots will move further away from each other. But now imagine an ant on the surface of the balloon walking from one of the dots to the other. So long as the ant is travelling faster than the dots are moving apart (due to the expansion) he will manage to walk from one dot to the other. So Andromeda and the Milky Way are heading towards each other because their mutual gravitational att

  30. Hey Gem, welcome aboard, the best thing is to get looking up at the sky, with binoculars if you can and start identifying some of the stars and constellations, that's hoe me and the wife started until I bought her a telescope one Christmas, now we've never looked back, it is a very engrosiing hobby, see if you can find a local club (sorry, I don't know your local area), but whatever you do, explore the night sky, there is so much to see up there and it's so amazing! Good luck with your exploration.

  31. Hello, welcome to SGL! If you can afford it then I would definitely recommend the Heritage 130P. I don't have one but they look great and I wish I had chosen one of them as my first starter scope! It would have been easier to store, easier to use, easier to transport. But that's what I get for buying a telescope and then joining SGL! (Still, My Mercury 707 still gives me great views) Just looked up the term "Clear Skies". Apparently someone call Galileo Galile invented the idea to explain why he saw lights in the sky!

  38. Evidently, you'll be able to hunt down cheaper telescopes and good bargains on the second hand market, but, as you'll appreciate, that could come with some risk. Potentially, places like ebay will have many poor quality scopes for sale, so you will need to know what you are looking for and you will need to ask the right questions. Expressions like 'top quality' or 'excellent condition' or 'unmarked' can be interpreted in different ways, so unless you can see the equipment in person and check it over youself, ultimately you're relying on only the seller's word which isn't such a favourable posi

  39. Download Stellarium. That'll tell you when Jupiter will be high at a reasonable time. At 3am is should have been reasonable, as it's 30 degrees up by then. Of course it will nicer when it hits 50 degrees, and that's not until almost 5 am. It's odd if at 3am you aren't seeing any detail. Either the seeing was really terrible or your scope wasn't collimated or both. A miss-collimated scope will produce blurry views. Hope that helps!
