  1. A couple of weeks ago I spent the day with two Year 5 classes in the Leeds primary school which our 9 year-old Godson attends. They are doing Space this half term, and as 'Auntie Helen knows a lot about space...' the teacher contacted me. We decided that I would do a more formal version of the stuff I did with the kids at SGL last year. So I again borrowed the meteorites and rocket making kit (from the Faulkes Telescope Project and AstroCymru) and paired them with 2 x 1-hour powerpoint sessions on meteorites/impacts in the morning and then rocket science in the afternoon. I must admit I wa

  2. This is a collaboration between me and Peter Rosén where my part mainly was the photon collection with my old trusty C14 and Peter took care of the processing. M82 has a large outflow of hydrogen perpendicular to the galaxy. Part of the hydrogen probably comes from an earlier close encounter with its neighbor M82 and it has triggered a massive star formation and also numerous supernova explosions. In our galaxy it can be lifetimes between supernova explosions but in the area from where the gas emanates in M82, it happens about once a decade according to the Wiki and these explosions blo

  3. NGC5466 is pretty remote globular cluster in Bootes. This cluster has been discovered by William Herschel in 1784. It lies about 52,000 light years away both from Earth and from galactic centre. Unusual thing in this cluster is significant horizontal branch of blue stars, and that can be seen in the image. Most of globular clusters contain only few of blue objects. I made this image at my backyard suburban observatory with Meade ACF 10" telescope, QHY163M camera and EQ6 mount. It is LRGB composite 20:18:12:15 frames, 2 minutes each one. Seeing was good, transparency medium, 1st quarter Mo

  5. Hi all, this is my attempt of M42 & The Running Man Nebula. This is my 1st attempt at M42, and 1st light with the Zenithstar. It consists of 28 90sec lights, 20 darks, 53 bias & 63 flats. This was so near the horizon, I never expected it to turn out quite like this. I hope you all like it. Kit:Zenithstar61, SA unguided, Canon600D (unmodded) & a lot of ambition. Taken from the Brecon Beacons, Wales. Thanks Ryan

  6. At 51.5 degrees North, Sherkin Island is the second most Southerly point in Ireland. At this latitude the Milky Way does not get very high in the sky. The forecast was set to clear at about 3am, and thankfully it did about 03:40, leaving me with 50 minutes to get the shoots. I had lugged 15Kg of gear a few kilometres down to the Horseshoe Cove to set up. This is 6 panes, each 25s ISO 10,000, at f/2.8 with a Canon 5D and 14mm lens. I stitched the pic in PTGui. Processed in LR and PS. The light on the horizon to the left is from the same town of Baltimore. While this was back

  10. Clouds, that is. It was looking lovely at 8pm but the Mak hadn't cooled yet so I got on it at about 9pm. I had a mosaic planned, but it was not to be. I'd grabbed a few panes worth of video when the cloud came in fast. Very photogenic though so I present for your enjoyment, the Moon Nebula I went to town with the targeted adjustment brush in Photoshop for.. lets call it visual impact! Oh and the panes I did manage to capture, assembled in full colour, FWIW. 500 of 3000 frames per pane. Pipp>AS!3>IMPPG. Plus an 'action' shot taken with iPhone (or why I still use a DS

  11. I and my girlfriend has come home from a one week travel at Malta, a small island in the Medeterranien Sea. About a mount before we go I came in contact with an amateur astronomer down there, Maurice. He invited me and my girfriend to visit him and his DIY built observatory. The observatory is built on top of his house and it has a real dome. If you find it interesting to read about it I have done a small report from our visit at the Malta observatory with photos: http://www.astrofriend.eu/astronomy/observatory-sites/malta-maurice-observatory/malta-maurice-observatory.html

  12. My attempt to take picture about Messier 13 was not easy with my alt-az mount + smartphone. Into okular I used 2x zoom to cut down the viggnettation and a little part of coma. I think, it is still good with 2x zoom, the stars looks round out. Celestron 8" SCT, alt - az mount, 25mm okular, Huawei P10 in monochrome mode, ISO 1000, 15 sec. Of course I used a very massive smartphone adapter. https://www.astroshop.de/kamerahalterungen/omegon-easypic-universal-smartphoneadapter/p,49763

  13. Hello, The first night of 2018 I was able to go stargazing was on the 29th of January. It was a really humid night with a gibbeous moon. I still managed to sketch a globular cluster, M53. I also made a timelapse (you can see me sketching at 0:12): Cheers José

  14. Hello fellow gazers... I started shooting this one back on Feb 20, when i grabbed 11 x 1200s of Ha subs. 4 of the 11 were not of great quality, due to some light intermittent clouds, but i included them anyway in the stack (such is the trust i place in APP's 'Quality' algorithm). Then on March 3 i finally got another clear night, so while i waited for the sports facilities floodlights to switch off, i grabbed a short set of 20 x 90s RGB subs (just the D5300 with no filter) so i could use them for RGB stars. Then afterwards managed to grab 12 x 1200s of OIII subs. It's been a b

  17. My setup is not really suited for Galaxy season so I decided to image the Virgo cluster to get lots of them into one shot. Pretty amazing how many there are! Thinking of how big our own Galaxy is, it makes me pretty confident that there is life out there somewhere… Data was taken over two successive nights with pretty good seeing conditions and a ‘Bortle 3’ sky. 75 x L 300s - FSQ85 - Moravian G2-8300 25 x R/G/B 300s - WO Star71 II - Moravian G2-8300 Mount: Avalon Linear (better quality version here: https://www.astrobin.com/338958/0/)

  18. Got up around 4.00 with the intention first of finding NGC 2146 and it’s supernova with the Dob but failed. The skies were slightly milky and it was not showing up. So, up to my rooftop perch and the Ioptron/Tak combination for the planets. Jupiter was showing bright and looked really good with lots of detail in the belts. I went back to it over a couple of hours and watched the Great Red Spot come around from the limb to the centre of the disc. Seeing deteriorated a bit but the spot was clear in moments of good seeing. It looked dark red but smaller than it has been and surrounded by mor

  20. 8.15pm, the first stars were appearing, 8SE out and cool, but there was poor transparency and a bright hazy Moon. Thought I'd try for some unvisited doubles. I initially aligned on the Moon, but apart from being blinded, it turned out not so good compared with the usual approach of using two named stars, which I then used. 25 CVn - binary, 1.7" separation. Located as usual with the SAO number, and confirmed by star patterns in the region. This should have been easily manageable, but the haziness was against me, and the target was fuzzy at x203, 169. At x113, although sharper, it

  23. Recently got myself a new smartphone. A Google Pixel 2. Which allegedly has the best camera ever seen on a smartphone. So, I thought I would grab a quick pic from my bedroom window last week of the Moon, Venus and Mercury. I am actually pleasantly surprised with how well this has come out.

  25. Personally I think 'save up for something better' is the most demotivating message you can give anyone wanting to try AP. My advice is get a second hand DSLR, a 600D is well within your budget, a 450D or 1000D rather less. Astro modded ones appear in the classifieds here from time to time and I recently got a modded 1000D as a second camera for £100. Use this to learn the craft and keep your change for accessories/software you need or future upgrades. You may find upgrading your mount or scope will bring greater improvements than a better camera or decide you simply don't

  26. Yesterday I collected a very nice, new to me WO EZTouch Alt Az mount from @Rob. I know it's not an AYO but it's as close to an AYO as this poor man is likely to get. I had a brief play tonight and I'm very pleased with it, the variable friction is a wonderful feature given the learning curve I'm facing with a Giro GR-2, but that's another thread. Really looking forward to getting some good use out of this mount.

  27. They have a few marks on them, mostly from the laser being too hot! All work ok though. I’ve tested on my finderscope guider and it works the way it should. I bought mounting bolts in nylon so it secures to most things either on the internal or outer diameter, and they shouldn’t scratch. 1 x ED80 600mm (setup for FF at 510mm) mask (black) 10 x 50mm SW finderscope masks (some blue some black) All I’m asking is that you cover postage/packaging £1 PayPal gift 1 mask per person please.

  28. Pretty much straight out of APP ( @Xiga big thanks to Ciaran for help on using this programme), with just a little adjustment in PS/GIMP. 106x300s ISO800, with 50% moon, ED80 I will try to process it later with new flats. I used existing flats but three dust bunnies have shifted so it made things worse, hence the crop. I seem to have picked up a few faint background galaxies, the guiding and star sizes shapes etc seems better than I've done to date. If I do a meridian flip, do the flats and bias automatically flip too? Any pointers welcome Thanks Adam

  29. This data has been sitting around for a year waiting for me to get around to process it, so here it is at long last (I don't think M106 has changed much in the past year). Captured in Spain on the TMB this was 11 hours 40 min total integration (12x300s R,G, and B, 50x300s L, 15x1200s Ha). The sharp-eyed might spot the faint Ha jets coming out from the centre of the galaxy.

  33. My first ever full arch Milky Way... all previous attempts in the last two years have ended in failure. Regarding the foreground: I really lucked out with this one. My two astro-buddies and I were cramped together on a helipad to the left and our red night lights were getting in each other's shots. So I ventured out into the field on the right and walked towards the fence to try to find a more secluded position. Then, just before sun up I shot a few quick landscape pano shots and as it turned out, my footprints from an hour ealier were just perfect to add interest to the scene!

  35. Currently staying near Knighton in mid Wales and we've kicked off with a great couple of days. Yesterday I took the kids to the Spaceguard Centre, thoroughly recommend going. Lovely walk today up Black Mountain (more of a hill). The barn we're staying in looks out right at it, so it was an obvious choice for our first proper walk. One slight incident though, while opening a gate that was wedged in by mud, it came of the hinges, I fell backwards, grabbed at a barb wire fence and landed on my bum in a stream with the gate pinning me down. This all sounds very dramatic, within minutes my wife an

  37. Thanks @Skipper Billy for starting this thread as I'm hoping to replace my Newt with a frac at sometime soon. I had basically narrowed it down to these two scopes, the Esprit as no one who owns one has a bad word to say about them and the Tak as every picture anyone posts on here are brilliant, that though is probably more to do with their skills in processing. Looking at the responses so far I think the Esprit's value for money will probably win over the Tak, telling my sweatheart that I've saved us £3000 by buying the Esprit maybe a good selling point

Last week a society friend and I ran a solar observing event at a local primary school as part of their science week. We picked a morning that was forecast to be clear (and it was !) and set up white light and Ha scopes in the playground. We ran 4 x 30 minute sessions with the year 5 classes at the school and then stayed on so younger pupils could also view through the scopes. We had loads of intelligent questions and some challenging ones as well. In total I reckon 200+ people observed t

  41. If I am time limited by short nights, clouds etc instead of imaging LLLLL, RRRRR, GGGGG, BBBBB etc I go for LRGB, LRGB, LRGB, LRGB, LRGB, LRGB etc but only refocus on the L and take my chances with the RG and B - its not ideal but saves a lot of time and the in focus L covers a multitude of sins in the 2x2 binned RGB!

  43. Hi all, this one's a bit different since, reduced to screen size, you can't see much. However, the idea is to open it up at full size and cruise around looking for tasty galaxies. This week, with guest Dave, we added 3 new widefiled panels to the existing top right one containing 'Markarian's Ball and Chain.' That was with the twin Tak/Atik 11000 rig. Meanwhile we shot relatively short runs on many of the nicer galaxies in the TEC140/Atik 460 to boost their resolution. They were combined in Registar then Photoshop. This is the top two-thirds of the project. The bottom third is still under

  47. Well, what can I say, DF is a thing of beauty.More detailed report to follow, I have picked it up but proper testing will hopefully take place once I drive it home. Got t2 BBHS mirror diagonal with 1,25 clamping on the nose part, but quick test with 4.7 ES eyepiece could not get into focus without 2inch extension being used...that sort of surprised me. Either it is the eyepeice (which I doubt) or I foolishly thought that T2 is sufficiently comparable in light path to full 2inch BBHS (which appears to have no problems).
