  1. Also, this video is amazing. Look at the moon halo at 1:46 as the clouds pass over. Such a beautiful sight. APOD: 2011 May 16 - Time Lapse Clouds and Sky Over the Canary Islands You may have to wait for the video to load.
  2. Looks like they had them in Sweden aswell on the 14th. SpaceWeather.com -- News and information about meteor showers, solar flares, auroras, and near-Earth asteroids
  3. Hello all, I have just watched Apollo 13 for the first time and loved it. I thought the music from it was great. I am listening to it as I am writing this and I have Goosebumps all over me. What is your favourite space music? I was thinking of making a playlist to listen to while observing.
  4. Is that adjustable in height? If so where can I get one?
  5. Hello, I just took a look out of my window to look at the moon which was behind thin cloud and there was a lovely bright halo around it. It was very colourful showing shades of orange. I tried to take a photo but I do not have a tripod and I could not really get the right exposure. When the moon drifted out of the cloud it showed a new halo, a smaller one with yellow in the inner bit and greeny blue on the outside halo. I have seen pictures of sun halos which are coursed by the light refracting through high up ice partials, but are moon halos coursed by the same thing? Anyway it was and still is a wonderful sight so I’m going back out to marvel at it. Thank you.
  6. O no, WHAT, its clear today so I was going to try and observe it for the first time.
  7. Thanks, I think I would straggle to see a mag 11 star even in the best of conditions let alone 18:23 lol. That’s a very nice video. Ive only observed 1 or 2 lunar occulations and on the first I remember being quite surprised (I don’t know why) at how fast the star disappears. I makes sense if you think about it but watching it through on stellarium it took ages to happen because the stars are scaled up to increase the screen brightness.
  8. There is one going through Devon tomorrow I think and I am just outside the predicted area, so if the skies are clear I’ll give it a shot. Anyway, thanks for clearing that one up Phil.
  9. Hi, Make sure you download stellarium if you haven’t already and set your scope up in the ocular function. This will allow you to see what you would see in the scope on the computer. It will allow you to mirror the image to the exact same image as in the scope. Then all you need to do is draw out some star hops on paper or take a laptop out. Take it slow. Start from the nearest visible naked eye star to the dso you want to find and match the star patterns up on the computer to those in the scope. You don’t want to get lost; you’ll have to start again. I have got the same scope as you and bought it at around the same time. You just need to practice. While star hopping use the lowest magnification (26x with the 25mm eyepiece I think) good luck.
  10. Thanks Luke, looks like a very useful website. It’s interesting that it lasts 2-3 secs. I suppose you could probably calculate the size and shape of the asteroid if you were observing all along the 20 miles by recording the time period when the star disappears. This is where amateur astronomers can play an important role:headbang:
  11. Hello, I was wandering if anyone had seen any asteroid occulations? They seem like they might be quite exiting; you never really think about other objects out there apart from planets and moons and to and to witness the presence of these elusive objects would be amazing. What am I likely to expect from an occulation of this type? I have found this website http://mpocc.astro.cz/2011/a11_01058.gif as an example of an occualtion and I am guessing that on the map, the area inbetween the faint lines are where it can be view from. Am I right? Thank you
  12. Yeh, you should be able to increase the shutter speed (make the exposure shorter) by turning to the sports mode on your camera (I think it should have one). That should stop the ghosting of thr moon aswell as show more detail.
  13. Thanks for your replies, I have actually already got GIMP, (I probably should have mentioned that:o). I just wanted the general consensus on what was the best and to know if any of the other programs could do any other useful things.
  14. Hello, I have tried to find various Photoshop like programs for editing things like star trails and sketches I do. There seem to be quite a lot of them, designed by different companies and some costing money! I am looking for a free one. Does a free one exist? And if so which one is the best? Thanks
  15. Nice image, you can see the dust lane very clearly. Next time you should post in the deep sky imaging section, there you will get lots of helpful advise.
  16. Hello, I have noticed quite a lot of these weird star patterns on stellarium. They are either long lines of faint stars or perfect circles of faint stars. I can only remember where two of them are: 1. One is around megrez in ursa major. If you go to a field of view (located on the bottom toolbar) of about 0.300 you should be able to see a ring of stars. 2.Another is located to the left of M107 if you are viewing at midnight. These patterns are long lines of stars. You should be able to see them at a FOV of 0.900. Does anyone know how these formed? And has anyone observed them? Thank you
  17. Sound like you had a good night. I hate having to pack up and call it a night. GoTo is not cheating, your just missing out on the most fun bit, the star hopping. (It really is fun.) And it makes the finding of an object so much more satisfying, saying that youve/ive found an object yourself/myself.
  18. Hello, I have had GIMP downloaded on my computer for quite a long time now but not done much with it (kind of forgot about it). But about a week ago I saw it mentioned in another thread and started playing with it. After much messing around with making people’s eyes different colours I had an idea that I could do some sketching of galaxies on it. So over the weekend, I visited my grandparents who have a house with pretty much no light pollution with the Milky Way just about visible. I took my scope and laptop out with a red filter over it to protect my night vision and found the pair of galaxies. I started by plotting the stars. I sort of got lost. There were more faint stars to put in but it was a bit difficult putting them in accurately. Then a marked the positions of the galaxies and started adding the all the detail I could see with the airbrush tool in shades of dark grey. The good thing about using the computer is that you can get the brightness petty much spot on. Anyway here it is. It’s probably a bit different from using pencil and paper but anyway, hope you like it.
  19. Thanks for your relies, The noise reduction can only be set to low and this does not stop the processing screen after the picture. Will it still work if I use burst mode with 30 sec exposures and just end up with 30 sec gaps in-between the star trails? It might not be that noticeable if I edit the gaps in the brighter stars in.
  20. Hello, I have a DSLR, (sort of, it does not have a removable lens. It kind of looks like one though) a panasonic lumix DMC-FZ8, and want to take some star trails pictures. My camera only goes up to 60 secs of exposure so I am thinking of doing 30 sec exposures and adding them together in startrails.exe. My problem is that if you take a picture above 2 secs, it takes the exact same time after the photo to process it into the memory or whatever it does. So for 30 secs it takes 30 secs after the picture has taken to process it. Is there any way to sort this out, will it be much of a problem, or does it mean I can’t take very good star trails? Thank you.
  21. Nice image. Can you just see mars to the top left of jupiter? Maybe.
  22. Hello and welcome to SGL. I think it takes about 30 mins for your eyes to get fully dark adapted. Make sure you get a deck chair so you can observe in comfort. A few good binocular objects are M44 the beehive cluster, M35 in Gemini, the double cluster in Perseus and M13 the bright globular cluster in Hercules. I hope you enjoy your stay here and your observing. Good luck
  23. Thats very nice. I cant wait for these objects to come into view at a reasonable hour so I can see them for the first time. Im also thinking about doing some sketching. It seems very fun and rewarding.
  24. Thats an amazing image. The moon looks really round and 3D. BTW, its a fantastic scope.
