    GRS Transit on Jupiter, crossing the meridian at 4.18am with Jupiter at just over 21 degrees altitude. GRS starts to come onto the disk at around 2.10am, disappearing at around 6.15am. A couple more events too, an Io Shadow Transit starting at 4.22am and an occultation or Ganymede at 4.29am. Full timings in the attachment. Best time to view is probably 5.18am with both shadow and GRS well positioned.
  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 all, after been put off by cloud last night, I left my rig setup overnight specifically to capture Jupiter in the small window of opportunity I had from my backyard. Seeing was pretty rubbish with 100% humidity & I had to shoot over house roofs, that said, this is my first real capture with my new ASI224 and I am fairly pleased with the results.

  4. 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
  5. 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!
  6. Celestron NexStar 4SE + 2x barlow (2650mm f/26), DMK41. Best 10% of 1000+ frames. Wish I had a colour sensor about now... Processing: Pre-process in PIPP, stack in AS!2 at 1.5x, wavelets in Registax 5, finish off in Photoshop Elements. I had to look it up, but the blob at around 11 o'clock position is Ganymede, and the speck to the left is Io. Any tips for improved imaging? I got the DMK41 primarily for solar/lunar and not planetary, so it isn't really built for speed and massive numbers of frames. Is a better strategy to go for longer exposures (to 1/15s) at low gain, or shorter exposures (1/100s or shorter?) at high gain - given that the camera tops out at 15 fps and seeing wasn't great? I forgot the exact settings but I think I tried shorter exposures at higher gain on this one in the hopes it would help with seeing related effects. Or maybe I could pick up a cheap colour planetary cam... I notice the QHY5 seems to have a 50fps crop mode which could have been useful... one to try next time! The wheels are in motion on new optics which would help in future too...

    Io shadow 2

    From the album: Jupiter

    Latest try at Jupiter, with GRS and Io's shadow., It MAY be that a slightly bright patch to the right of the GRS is Io or I may be fooling myself...

    As per Chris's post, GRS and a shadow transit of Io are visible tomorrow morning, weather permitting of course! Io Shadow Transit starts at 2:28am, finishing at 4:39am GRS Transits at 3:32am, and Jupiter itself transits the meridian at 4:53am Between 3:30 and 4am could be an optimum time, Jupiter at around 19 degrees and above, not far off its highest at 21 degrees.
  10. 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
  11. 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
  12. 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
  13. 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/
  14. 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.
  15. Jupiter with its Great Red Spot visible...flanked by Ganymede on the left and Io on the right. 23rd January 2015, one of the coldest sessions I've endured so far at -5° Celsius and ice over everything except the front of the scope
  16. Hi all, Thought we would share our image of Jupiter from the 6/4/15 ... this is the first time we have seen the Red Spot. We had spent ages trying to get pics with a Canon and tried the QHY5 camera we purchased as a guide scope to video it instead and then stacked the frames. It worked a treat ... still can't believe we got a pic of it after all this time!

    Jupiter Ani

    From the album: Davide's Astro Pics

    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

  21. Seeing was mostly poor, but I am quite happy with how it came out
  22. Hi all, A period of decent seeing and clear skies (!) on 22nd Jan landed me a decent view of the Big One. More data to process and a de-rotation session should improve on this (hopefully!)...
  23. 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?
  24. 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
  25. 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.
