  1. Last night was the "Virtual Star Party", a live show that lets amateur and professional astronomers show the night sky from their telescopes. If you've never seen it, or missed out on last night's episode, catch it here: Last night I brought Jupiter and Mars to the VSP, and despite it being 3:30am when the show finished for me, I hung on for an extra hour to get my first image of Saturn for 2014! All the planets (and Europa) where shot using the exact same set up, so the image is a good example of their relative sizes currently. Equipment: Meade LX90 8" SCT Meade 2x Shorty Barlow ASI120mc! My scope needs collimation as it was recently repaired and seeing conditions where less than favorable, but no matter how many times I look through my scope, these planets blow me away!
  2. Here is my video of the double shadow transits of Io and Europa in color with a little processing. More musical atmosphere with "La Langue des Sentiments". Is it easier to see the shadows in this color image? Kaleidoscopic skies! Reggie
  3. Hi everyone. I recently acquired a ZWO ASI120MC-S and so with the bright summer skies I've turned towards solar and planetary lately. I'm not great at either, but I'm learning This is the result of my efforts from last night and I'm quite pleased with how it turned out given it was ~3-4 hours of sitting in the relative cold of my front garden. I've never managed to time weather & my availability with the GRS or a Jovian moon transit before so that's two firsts for me. The seeing was "soupy" to put it lightly, especially towards the end when the planet got lower in the sky and ended up over the roof of a house across the road, but I can't complain - at least it was clear! I took a video around every 5 minutes for almost 2 hours, stacked the best frames, then compiled into an animation of 19 frames that loops back & forth. Io started off about 1/3 of the way across the face of the planet when I started recording data so it's a bit tough to see but you can follow it back across once it pops out the other side. Thanks for looking! I hope the attachment works correctly because I couldn't seem to get the gif size down below ~14mb, so I apologise to anyone on a slow connection! Imgur link for the animation: http://imgur.com/HN2HuGn Gear: Skywatcher Skyliner 200P 8" newt with Skywatcher 3x 3-element barlow (3600 mm, f/18) Skywatcher NEQ6-Pro Synscan (unguided) ZWO ASI120MC-S camera Acquisition & Processing: - 19 individual images spaced approximately every 5 minutes from 21:55 to 23:45 BST - Firecapture [gain = 55-65, exposure = 20-25 ms, 960x960 1x1 bin] - 4500-5000 frames per image @ 45-50 FPS - Best 500 frames stacked per image in Autostakkert!2 - Wavelets and colour balance in Registax 6 - GIF created in Photoshop CC
  4. Yesterday I got a tip from my dear friend Peter Rosén in Stockholm that Jupiters moons Io and Europa were up to something special. I got my gear ready and did this short animation. Its taken between 20:10:37 and 20:55:00 UTC using my 8" telescope with a 2.5x PowerMate and a Imaging Source DBK21 CCD-camera. As you can see from the still frame, at one moment the two moons were perfectly aligned at the right hand side of Jupiter. Thanks Peter for the tip!
  5. First night in back garden for what seems like forever, had an interesting session. Set the C8 on Jupiter while I dabbled with the star adventurer mini / Nikon D5300 / 105 2.8 macro. Tried too many things as failed miserably on focus with the D5300, Jupiter was just clearing neighbours roofs ... Got quite disheartened by 3am so took cameras off and had a peak at M13 before packing up. Absolutely beautiful ! C8 with ES 14 mm. Thought I'd try imaging it but only had the Nikon with William optics flattener attached ... Managed 20 x 15 seconds as hadn't polar aligned for Jupiter. Good luck all with opposition on the 8 th
  6. Double transits of Io and Europa across Jupiter, shot just after midnight with the Orion Deep Space Video Camera II through the Orion 127mm Mak. Io's shadow is more prominent on the left, on the upper belt. Europa's shadow is smaller and is located on the extreme upper right of Jupiter (above the belt); it peeks in and out because of the less-than-optimal seeing. Also, enjoy some original space music by my band, THE FALSE DAWN, La Langue des Sentiments (The Language of Feeling). Clear skies! Reggie
  7. A brief clear patch of sky on March 14th allowed me to be able to capture a few shots of Jupiter with three of its four Galilean Moons; Io, Ganymede, and Europa. After taking this the cloud rolled in again of course, but this was the first astro picture I've been able to take since late January. Made from 1,000 frame video captured with FireCapture and processed in PIPP, Registax, and Photoshop. Equipment: Celestron NexStar 127 SLT Alt-Az Mount ZWO ASI120 MC imaging camera x2 Barlow lens
  8. Hi, after a long time I finally had time and a reason to image a bit. And it was NICE. And cold ;-) But for good, all my equipment worked. Dewcap heater keept the corrector plate clean. Motor Focusser worked via Bluetooth. Celestron Mak127 NexstarSLT, 2x Barlow (cheap one), Nikon D5100. After testing a Rasperry Pi cam as Astrocam (worked soso...) I started just in time to get the entering of Europa. I tried several images but so far only the FullHD videos seem to have good data in them. The attached image is one I processed just after the session (3 o Clock in the night). Today I realized that I just choosed the one where Europa just had entered, tired and frozen I tried to see Europa more on the planetary disk and completely ignored the pimple "artifact" left :-) Processed with PIPP for cropping and pre-process, then Autostakkert! (3x drizzle) and then Registaxx for the Wavelet magic. Today I will look if there is more data to process. The entering of Io I watched in the eyepiece, quite interesting! Cheers, Carsten
  9. I hope I'm doing this right because I haven't posted a link on this this site before, but I wanted to share this short video clip of a time-lapse of Jupiter and its moons. Please let me know if there is a better way do this This is a very short time-lapse of Jupiter and its Gallilean moons taken on 2nd February 2015. One shot was taken every six minutes starting from 01:27 and ending at 03:40. This 24 frame sequence shows Io and its shadow transiting Jupiter while on the left Ganymede moves towards the planet and conjuncts with Callisto which is moving away from it. At the end of the sequence Io clears the planet and conjuncts with Europa which then disappears into shadow. Throughout the sequence the Great Red Spot can be seen moving across the frame as Jupiter rotates. Conditions were very good on this night with the best seeing we've had for some time which made processing so much easier than it was for the triple moon shadow conjunction the week before. Playback is at 6 fps. Here is a still from the sequence...the video is here: https://www.flickr.com/photos/davidesimonetti/16444555332/
  10. Jupiter with two of its moons; Europa furthest away followed by Io which had just passed in front of the planet on 25/11/2014. This frame was taken from a short test animation of Jupiter's moons made in preparation for a longer sequence to be done when we finally get a clear night. Unfortunately the test sequence was spoiled by some unwelcome cloud but there were some nice frames before the weather turned.
  11. Well it's certainly winter now, with the average temperature being in the minus zone now! Still waiting on Orion to ship a dew band to Telescope House - it's been over a month now, which reminds me why astronomy has more than mechanical and weather frustrations! I really must stop attempting to focus my webcam/barlow using the primary mirror, and remember to plug in my crayford, though I'd kill for some kind of remote focusing device! I had PHD do some guiding for me, but from my porch I couldn't get a star to sort out my awful dec drift, so PHD was having to work hard (2000ms hard on dec). Still, this remains one of my best efforts and the first time I've a) seen the shadow from a Jovian moon on Jupiter's upper atmosphere, and first attempt at making a time lapse! Tech details: Shot between 21:15GMT and 22:30 GMT on the 29th of November 2012. Shot using a Meade LX90 8" SCT with the Orion StarShoot IV Colour Imager, in conjunction with a Meade 3x barlow. 3x barlow takes the scope to: f/30 | 6096mm fl Seeing was variable, but mostly average - 6/10

    An experiment in creating an animation of Jupiter and its moons. This is just a test to work out settings and timings etc for a longer sequence later. One frame is a little spoiled by cloud. It is 14 frames each one made from 100 frame videos of which the best 50% were processed in Registax. Created on 25/11/2014

  13. From the album: Jupiter

    I love to watch the Galilean Moons play out their celestial dance around Jupiter. In this image Europa is about to be occulted by the Jovian disc , Io is the nearer of the three planets with Ganymede as backstop. Callisto is out of the image frame. This image is the combination of two stills taken from two separate video runs. 127mm Meade Apo refractor, x2.5 Barlow, QHY5-11 planetary camera, NEQ6Pro on new permanent pier.
  14. From the album: Lunar and Planetary Images

    Moon and Jupiter showing 3 of it's Galilean moons. From top to bottom Europa, Ganymede and Callisto. Io was behind Jupiter at the time this was taken. Taken using Canon 100D DSLR. Tweaked in PS Elements 11.

  16. Seeing was mostly poor, but I am quite happy with how it came out
  17. 17 frame animation. Seeing improved during the session. Europa itself becomes easier to see. The shadow is easily visible.Skymax 180 7″ Maksutov-Cass at f30 (x2 barlow)Imaging Source DBK 21AU618.as 17x90s AVI 60fpsCaptured with FireCapture, Stacking in AutoStakkert Wavelets in Registax, processing and rendering in Photoshop CC2017-05-04 21:22 UT – 22:11 UT, Seeing: III-IV
  18. It was good seeing (I think!?) last night and I saw a moon dissappear at around 9:30 and another appear around 10:30! WOW. Anyone know which they were?,.... must have been the innermost two and I couldn't tell whether they were going behind or in front, as I don't think mt scope will resolve the shadows?
  19. I haven't played with Jupiter for a while, or any other planets for that matter, so I thought I'd put that right. Now is a good time to observe and image Jupiter as it is relatively close to us at this time of year - Jupiter comes into opposition on March 8th when it makes its closest approach to Earth. This was taken at 02:26 on February 12th (just before cloud rolled in and ended the session). Also visible are the moons Europa and Io. Europa is the moon appearing closest to the planet and its shadow is clearly visible on Jupiter's North Equatorial Band as it transits Jupiter to be followed by Europa itself. There are some other interesting features visible on Jupiter including what I'm guessing is a storm on the South Temperate Belt which I hadn't noticed before (the oval shape between the south polar region and the South Equatorial Belt). The image is made from a 1000 frame video captured using FireCapture and processed in PIPP and Registax. Post processing and cropping was done in Photoshop. Equipment: Celestron NexStar 127 SLT GoTo AltAz mount with homemade wedge ZWO ASI120 MC imaging camera
  20. Here's my best capture so far of Jupiter reaching the limits of my equipment. Taken at around 0:30 on 11th Feb 2016, 4 subs of Jupiter taken at ISO400 1/200sec f/12.7 & 4 subs of the moons taken at ISO800 1/2sec f/12.7. Each set of sub were processed through PIPP, then AS2! and then selective sharpening in PS before being composited into one single image to show planet & moons. My meager equipment being an Olympus E-510 4/3 dSLR attached to a 40 year old M42 mount 400mm f/6.3 preset lens via an adaptor and a x2 teleconveter. This gave me a equivalent focal length of 1600mm at full frame but my f/ratio reduced to f/12.7 (roughly). Having said that, I am overjoyed with the result & getting some visible banding on Jupiter. Being able to capture any detail at all from Jupiter with my current setup has been a goal of mine for ages, now ticked off. Two images here, both the same just one is labelled for ease.

  21. iPhone picture taken April 15th from central Illinois, USA. Not bad, all things considered. A few days later, I acquired a Celestron Solar Sustem Imager camera.

  23. Double exposure of Jupiter with two of its moons - Ganymede in the top right of the frame and Europa at the bottom left. The Great Red Spot on Jupiter is just visible in the southern hemisphere of the planet. London 24 November 2014
  24. My goodness, the weather must be wonky. That's three reasonable observing nights in a week and a bit! Still, tonight's atmosphere was nowhere as stable as Saturday's so it was low resolution imagery only, allowing a far shorter exposure per frame, 1/60th second. Still, processing the video I had to go down to only 20% best frames to get a decent image...
  25. Hi All, After high cloud passed through the seeing was fairly respectable. A lovely view of Jupiter, with the Great Red Spot on disc. Europa was just off planet with its shadow transiting near the GRS. Best regards, Pete Lawrence
