untilGRS 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.

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... -
The GRS is perfectly positioned right now on Jupiter, pretty much dead centre a few minutes ago. The seeing seems pretty decent here in Bedfordshire at the moment as well!

Hi all. Sharing my capture of Jupiter from 19 April 2017. The video comprises frames from 1622UT to 1718UT and shows the GRS traversing the planet. Video can be viewed at either the youtube or attachment link below. https://youtu.be/8M7d3m34c5I 2017-04-19-1622_1-RGB_pipp_x264.mp4 Equipment used: Celestron C8, QHY5L-II-C, GSOx2.5barlow -
I took this image handheld at the eyepiece with a iPhone this evening. Seeing was fabulous tonight and the visual views quite amazing. This is an extremely poor representation of those views, but does show the GRS (squinting also helps ???) I can also just make out the dark oval in the NEB in line with GRS, plus the northern and southern temperate zones and belts.

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!

Timelapse of Jupiter's GRS transiting. 23:08 to 00:06 (my phone's battery died), 25-26th of April 2015. The seeing was kinda bad, so that was a bummer, but it's something I've been wanting to do.. I took two 20sec videos, every 2min (very roughly). Aligned the drifting with PiPP. Processed in RegiStax, kept the best 15% out of ~1300 frames (of the combined 2 vids) to create the first frame of the timelapse, and so on with the next pair of vids.. iPhone 4, connected to a 10mm eyepiece + 2x barlow Skywatcher 250px FlexTube I think that the first frame (of the 25 in the timelapse) turned out the best: -
Last year I didn't have a barlow yet, I kept taking photos of Jupiter with great quality mostly. This year I finally got my barlow and was severely disappointed with my first Jupiter shot. Blurry, dark, and bad. Then my 2nd shot was a bit better, then the 3rd better still. I've somehow managed to keep getting better shots this year, this being my 5th. This is now easily my best shot of Jupiter ever, or of anything really in terms of quality. I'm really quite pleased with it. 6 Inch Mak 1800mm Skywatcher + EQ5 Explore Scientific 2x Focal Extender (Barlow basically) ZWO ASI 120 MC 2 minutes of footage FireCapture + Astrostackert + Registax + GIMP + Lightroom 2017-04-09 - 0:46 local time Taken from Amsterdam, Netherlands

untilAs 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.

First time imaging since April of last year! Managed to grab three 1000 frame videos between it being dark enough for me to see Jupiter and it going behind the row of 40 foot Sycamore, Oak and Beech trees that back onto our garden. Scope: Celestron C9.25; Mount: CGEM; Camera: QHY5LIIc; Lens: Explore Scientific x3 Telextender; Capture Software: EZPlanetary 3 x 1000 frame videos, centred and cropped in PIPP, stacked & RGB aligned in Autostakkert 2 with wavelets done in Registax 6; post processing and turning into a GIF. in PS CS4 Seeing was very poor with some very high thin cloud. I think my focus was also off and as I haven't used my scope in anger for well over a year the collimation is probably way off. But hey-ho, at least I've finally managed to enter something into one of these competitions instead of living vicariously through others efforts! ? -
As per the heads up, GRS was transiting at 6.02am this morning, so with the promise of clear skies the alarm was set. I was too lazy to setup the AZGTi further down the garden, which would have been better, so I was stuck closer to the house and trees with the scope on the Giro-WR. Lovely views right from the start really, GRS heading for the meridian showing some nice colour although not as dramatic as I've seen it in the past. I could see the white separation between GRS and SEB, north and south polar regions and what I assume was the South Temperate belt and Zone. Hints of a festoon dropping into the Equatorial Band. This was another occasion when I tried cyclops first, then switched to the binoviewers to see if I preferred it. Binoviewing, on this occasion, definitely made the detail easier to access although that has not always been the case for me. I was at x230 ish and floaters were well controlled. I thought the seeing dropped off after a while, until I defocussed and realized I was observing through the twigs of one of our trees! Amazing that I could still see some detail even then. Loppers required before the next outing I think, plus putting the other pillar extension on! What a lovely way to start the day. Blackbird singing his heart out and the gulls floating gently overhead on their way to the reservoirs. The Parakeets had yet to start their noisy morning commute! Two last surprises. I thought Saturn might be visible, and did catch it just before it was occulted by......my house! OK views but good just to see it again. Finally, despite it being quite light at gone 6am, Arcturus was clear and I could also still see Izar so I popped the scope onto it. What a beautiful sight! Very well controlled faint diffraction ring around Izar and its secondary was as clear as I've seen it, lovely separation and nice almost greenish blue colour to my eye. It has always been bluish grey to me, so perhaps just a trick of the daylight. Great way to finish off, then back in for a warming cuppa and a little three year old who wanted a cuddle .

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!

Finished my shift behind the bar at got home at 1:30am - the sky was clear and the air rather fresh. So gulped down my Maccies and set the scope up. Could not for the life of me get PHD to co-operate so went for some manual guiding. The sequence was shot between 3:30am to 4:30am and used PIPP and Registax to make a raw TIF and then used Photoshop's "Smart Sharpen" to produce the images. Why no wavelets? Well if I could ever get wavelets to produce a nice image, or any advantage over PS, it will be a blue moon...oh wait, erm it is, but still I can't get that wretched program to do anything nice to my images. Anyhow, second attempt and really excited to see a planet "rotate" for the first time

Hiya, a glance at Jovemoons yesterday afternoon indicated that the GRS would be nicely positioned early enough in the evening for the kids to have a look. So, I set up the scope around 7pm, and we had a look. For me, seeing wasn't great, but the GRS did shimmer into view from time to time as the planet drifted down through the FOV. My eldest boy (10) had a look, and, though it took him a little while to get his eye in, he reported seeing it, but not very clearly – it definitely came and went. Around 8 my wife and youngest son (8) came home and had a look. My wife initially struggled to see the GRS, but eventually got there. My youngest, though, as soon as he put his eye to the EP exclaimed 'Wow! The Great Red Spot!' He said it was really clear and red ... Even at 240 times mag he said the GRS was clear, but a bit fuzzy, whilst to me the planet was better at x136 in the ES 8.8. Oh, for younger eyes ... Kev

Jupiter shot with an 8" Meade LX90 SCT, 3x Meade Shorty Barlow and the ASI120mc [Gamma 50 | Gain 100 | ROI 576*576 | 6ms] This was one image from a sequence of 26, the plan was originally to capture a full rotation, but five minutes after this shot, the sky had been covered with a thick blanket of clouds, so the attempt had to be abandoned. For some reason this image is noisier than my past few attempts, yet I had almost identical settings, that aside, I like the fact I was able to pick up a small, darker knot in the center of the GRS and comparing this image to others I have taken last month, and prior, I can spot differences in the knots and twists present in the cloud layers.

I decided to try to get the GRS last night (my 4th Jupiter attempt). The seeing wasn't great and I live in the middle of a city (my scope is usually set up 20ft from a streetlamp!). This is the first image produced from the batch of movies I took last night on my 600D. I have other files to try processing, so I may or may not get something better! Details: Eyepiece projection on Baader Hyperion Zoom at 8mm. (I had my 2.25x Barlow out and forgot to use it!) HD video zoomed 3x at ISO 800. Processed using PIPP, JPEGCrops and Registax 6.

September 4th @ 5:59am from Mansfield, England. Seeing conditions where terrible, telescope saturated in dew and my power pack just doesn't seem to be lasting, indeed slewing the scope got incredibly sloppy, and stuttering. The Sun was well on it's way by this point, the sky was blue and the few clouds had soft pink hues. But it is, as ever so worth it, whilst this image is hardly going to win me prizes, it amazes me every time I look at Jupiter and that Great Red Spot. That spot, a storm in Jupiter's atmosphere would neatly fit Earth with in it. Setup was: Meade LX90 8" SCT 2x + 3x Meade Shorty Barlow, giving me 5x 2032mm and f/50 ZWO ASI120mc Firecapture 2.3 Photoshop for sharpening and histogram stretch. This image is 1-2-1, so exactly as it appears on my camera's sensor. By this point I was just mucking around, and trying out ridiculous magnification, fully knowing that I was going to far, but I was about to pack up, so thought, I might as well give it a whirl! http://youtu.be/iN-R_WioHOA Video shows Jupiter on my screen, the sky conditions and gives you a feel for my setup, and location.
