  1. Hi all, I'm hoping for a diagnosis as to why I'm seeing Jupiter the way I'm seeing it. I'm still a total newbie having got my first telescope at the start of December and managing half a dozen sessions since then. My scope is a Skywatcher Heritage 114P Virtuoso (114/500 F4.38). When viewing Jupiter this morning (in Glasgow 6:30 - 7:30) and on a previous occasion it's been very bright and I've only had very fleeting hints of bands. I've attached a still and a link to a short video clip. I've got no plans for astrophotography but having a smartphone attached at times is helpful for my 4 year old daughter and the video clip is a fair representation of what I was seeing through the eyepiece. This was viewing through a 6mm plossl and 2x Barlow (167x) but the image was similar but smaller using the 6mm alone. The scope was given about 45mins calling time (outside temp was -2) I know there are a number of factors in play here, but the ones that came to mind are: Should I be using a filter to lessen the brightness of Jupiter? Is my fine-tuning of the focuser not quite good enough yet? How much of the problem is the fact my table is on a decking that has a bit of shake. Will setting up the Virtuoso's motorised tracking ability improve the image? The "seeing" wasn't good enough? I've reached the limit of the scope? I could try a higher eyepiece and take it up towards the max 228x (although even at 167x the exit pupil is down to 0.7mm) Something else entirely I've not thought of. Any suggestions that will help me improve my viewing much appreciated. Thanks David Video - Jupiter 27 Dec

  3. Evening, NASA has released the perijove 7 pass of the JunoCam images over the GRS and I fancy giving them a process. https://www.missionjuno.swri.edu/junocam/processing?phases[]=PERIJOVE+7 I've done simple level and curves in PS but I'd like to see if I can get better quality using the individual R, G, B images. Would these be processed in the same way as you would process separate images from a mono camera? I don't know how to do that but if this was the way to go I'd be willing to learn. Has anyone else had a go on Juno images? Thanks everyone, elliot.
  4. Two years I've been actively learning and pursuing my love of astronomy (well 18 months, as I spent six months in Australia). In that time I've taught myself, gleaned knowledge from our collective friend Google and practiced when the clouds let me! So much more to learn, refine, practice and enjoy. I have photographed Uranus and Venus, but only have a single photo of each. Nothing quite gets the attention and thus demonstrates evolution quite as much as Jupiter and Saturn. The first photo on both rows was produced by a Nikon D300 DSLR,, the second photo in each row was taken using the Orion Starshoot Colour Solar Imager IV, a 15 FPS peak beginners cam, that offered me my first clues as to the details you can see. The last two Saturn photos are taken on the ASI120mc camera, practice in processing and improved conditions lead to the last evolution with Saturn. The 3rd Jupiter from the left was taken with the Orion Starshoot again, having learned more about processing, and the final Jupiter was taken using the ASI120mc at the start of this week, and is a single frame from a short 22 frame animation of Jupiter and the moon Callisto. Each photo was taken through my Meade LX90 8" SCT, and each photo, at the time, delighted me. Still, I dream of taking better photos of both targets, and for the first time ever, Mars!
  5. Hi Stargazers, After a lot of work and help from the great Damian Peach I managed to get some really good images of Jupiter Mars and Saturn despite a total spend of just £100... and I made another bonkers Astrobiscuit video about it which I hope you enjoy. Mr Peach really helped me pick my nights to image and the other big surprise was how good the canon 600D is at planetary. All comments/ advice/ criticisms most welcome...
  6. These pictures were taken over two observing sessions (April 20 & 24th) using my Nikon D3200 with my 127mm and 180mm Maks using the Meade Series 4000 8-24mm zoom lens and a Shorty 2x barlow. I set the ISO at 6400 and took several shots between 1/250 and 1/320 sec. I did some post-processing in Photoshop to adjust levels. These are the best of those shots which look pretty close to what I see through the eyepiece of each Mak respectively. This first picture was taken through my 127mm Mak with the Meade zoomed in: zoomed in with barlow: This image was taken through my 180mm "Rolls-Royce" Mak with the Meade zoomed out: and zoomed in (no barlow): Nowhere near Hubble, but almost exactly what I see at the eyepiece (with a little enhanced color)!

    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.
  9. Here's my second attempt withe the ASI120mm with RGB filter from Baader, I tried using the RRGB as suggested by THEO here on SGL for the extra luminance and I do think it's brought out a bit more detail. I know this has been contended before but what's the opinion on the Televue 2.5 powermate as opposed to the Revelation one I using?. Thanks Campbell
  10. On 17.06 early morning Jupiter will be quite close to the Moon. Day before it will be further away but still using the Moon as a guide point it should be "easy" to find Jupiter on daylight sky (via a finderscope). It's a good opportunity to take some early images and check what's going on Jupiter (like NTB disturbance - http://www.pvol.ehu.es/pvol/ ). As it's daylight using a dew shield to block direct sunlight is a good idea. For imaging you could try to change the gamma (make it darker, for TIS cams it's moving it up). Also infrared/red filters will be much better than green/blue due to glowing sky And be careful not to point the scope at the Sun.
  11. Been meaning to post this for a while so here is my image from that night. So I set up the scope with a view to letting it cool a little longer than it had been already and looked at Jupiter Guide app on my iphone and saw that the GRS was just finishing transiting across the disc so I whacked the 2x TV powermate and ASI120MC on and messed about with focus quickly and fired off a total of 5 avis. Below is the best image. The avi was 3024 frames and put through PIPP. I then ran it through registax 5.1 which decided to stack 2475 frames then I did the wavelets in there too. I did a little Unsharp Mask in PS CS2 also. The seeing was a little better at times but still not great I dont think. The jetsream was above us still so I don't think that helped at all. 22.12.2013 2475 of 3000 withUS by Gattouomo161, on Flickr
  12. Thinks its about my 53rd actually but 'My 53rd Jupiter' doesn't quite have the same ring as 'my first Jupiter' This is from stupid o clock this morning (7th October). Taken through the setup in my signature using an IR block filter. Seeing was absolutely horrible when I first got going but very suddenly went steady as a rock. Which was nice. This is the best of the bunch.
  13. 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!
  14. Here's a couple of quick hand held shots from yesterday (30/6/15) of the conjunction. Not sure why I was too lazy to get the tripod out and do a proper job... anyhow here they are (might need to zoom in a bit on the wide shot to actual see the planets!). Both taken with a Canon EOS700D with a 50mm EF lens. The upload compression does take a bit away from them. Too much wispy cloud to get anything tonight... Cheers, Rob

  17. This is just a log of my observations last night from my balcony. It has quite a restricted view due to it being recessed so the floor above me gets in the way. It faces south-east-east and I have around 80-90 degrees of azimuth view. If you’re prepared to watch the constellations appear it is ok and put up with the streetlights on the paths it’s ok. I have places nearby where I can set up to get a better view of the sky but it’s summers and I could hear some people having a party in the park. I thought I’d leave them to it as it will be cold in the winter and the night time park will hopefully be empty! I was using my 102mm Mak on an eq2. I’d been hoping to have another attempt at the Ring Nebula in Lyra but the floor above me was getting in the way. I should have got out a bit sooner – with it not really getting dark enough until ~2330 and it going out of view for my viewing spot I’ve only got a short window of opportunity for this target at the moment. So I settled for Albireo. This was the first time I’d gone for this double in Cygnus and it’s a lovely sight. A warm orange spot with it’s hot blue partner. It’s not as hard to split as the Double double (which isn’t hard either but it’s the only double I’ve seen so far which I know the name of J ). I then decided to try and find M31 which isn’t visible to the naked eye for my location but the Andromeda constellation was easy to make out by following along from the belly of Pegasus. M31 proved a hard target to find at first. I’d initially started to use the two stars I could see that formed the waist of Andromeda which seemed from Stellarium could be used as a pointer up towards M31 but no amount of wriggling the scope whilst moving up worked so I consulted Stellarium again. Although I can’t see Polaris to polar align I can get a good enough polar alignment by pointing the polar axis north and the latitude for my location. So I could see that if I went up to the centre of the cross of Cygnus (Sadr), moved my declination up a couple of degrees and then scanned back with RA I might hit M31. Whilst getting my up and down mixed up on my declination axis, I happened across a star cluster which took me by surprise a bit. It seemed that I’d mistakenly found M29 after checking with Stellarium. After M29 I decided to put the scope in the right position I’d intended to scan back to M31 from Sadr in Cygnus. This approach didn’t help either! Back to the drawing board. I used the star near the head of Andromeda as a guide next and moved my declination up whilst giving the scope a wiggle and M31 came in to view. In my little Mak it was only the smudge of the centre but I was surprised how big the smudge was. I was expecting the core to appear smaller but I would estimate that I could see around 0.2 to 0.3 of a degree (I was using a 20mm Erfle which gives me ~1 degree in my scope). Having found M31 I was starting to notice more stars in the sky now. I could see the two brightest stars of Aries and the Triangulum so decided to attempt M33. I spent ages trying to find this but couldn’t do it. After doing some research today though it seems that M33 surface brightness is very low so maybe my scope is too small and I have to be a bit more patient when scanning the sky. The same research threw up the obvious question as to why I didn’t see M32. I should have been able to see it with M31 however I probably mistook it for a star. Now I know how to get M31 I’ll look out for it next time. My next target for the night was M34 as I felt this would be easy to find by scanning in RA from Almaak in Andromeda. Whilst lining up on Almaak I noticed this was double with a small companion. This was a double that I was going to put a name to! I’d seen a few without naming them but it’s so easy to find in Stellarium that I had no excuse although I was a bit thrown out when Stellarium didn’t show it as a double in ocular view. Some wiki research today confirmed this though and Almaak’s companion is a double itself but they are seperated by less than an arc second so not sure if I have the resolving power to try this when I go back to it. I found M34 after looking at the Almaak double. It wasn’t hard to find this time. Whilst the open clusters are nice and I like the way they jump out at you as you’re scanning across I must admit I preferred viewing M13 when I first found it. Even though I couldn’t really resolve stars in M13 I just found it a more exciting target. I suppose as it seems like a galaxy within a galaxy. I could now see Jupiter rising through some trees in the distance so tried to get the double cluster but I was just restricted by the floor above again and I could only see the southern half of Cassiopeia so I went to M45 which I could just see as a smudge 20 degrees or so above the horizon. There’s no way I can get all of the Pleiades in my FOV but it was fun scanning around it and all the other stars appear within it. Finally Jupiter had cleared the trees so I concentrated on this now. The seeing was quite bad, the transparency was getting worse (a haze was starting to develop around the planet) and Jupiter was still quite low.I found that my 10mm plossl was giving me a bit too much magnification and I was better of using my 15mm or my 20mm erfle with the barlow cap in the end to give ~100x magnification. Detail was hard to make out though and I was restricted to seeing 2 bands of brick colour on against the cream background. Unfortunately the moons were nicely spread out this time; I’d been hoping for a repeat of when I watched one of the rise from behind Jupiter a week ago. I’m looking forward to when Jupiter starts rising earlier in the autumn so I can view it higher in the sky to beat the seeing before the Sun rises. So that was last night on my balcony waiting for the earth to spin. Next week looks good my way for weather so hopefully I can repeat it soon.
  18. From the album: Planetary Images

    Taken on 5th Nov 2012 from backgarden using double staked barlows x2 x2.25 with 1100d with C6SE Using BYE stacked in Registax6 Seeing poor
  19. Had a brief but very enjoyable observing session with my two little ones (son, 5 and daughter, 61/2). Both were amazed to see the bands and the GRS on Jupiter, and the 'lumps and bumps' on the Moon, and I was really impressed with the crisp clear views from my little Mak 90 with a 15mm BST Starguider (and its Virtuoso mount is so easy to set up). I switched the 15mm BST for the supplied 10mm Skywatcher eyepiece to enlarge the view and the drop in quality was quite noticeable. So I took it out and barlowed the 15mm with a Baader 2.25x and Jupiter was just great to observe, large enough to be interesting for the children and clear enough to see all its main features. After we came in I fired up Stellarium to show them what we'd just seen - they had both picked up on the four moons we could see - and they immediately recognised everything and also the change in orientation when I switched Stellarium's oculars plug-in on. My daughter wanted to know the names of the moons too. They both wanted to know why no-one lived there, so that took a while (mental note - I must show them the Voyager documentary that explains how far away the outer planets are, and de Grasse Tyson's Cosmos episode with the GRS in it). Got them to bed, had something to eat and I've only now come in from observing Jupiter - because the clouds are rolling in - and while the seeing was intermittently fairly hazy and very clear, it was well worth waiting for Jupiter to be higher in the sky - the clear patches really were just that. At the moment I'm post-op and can't do any heavy lifting, hence using the Mak rather than my 150PDS/HEQ5, but the little Mak is rapidly becoming my preferred scope, especially for quick sessions and definitely when the youngsters join in. Here's to more clear (ish) skies!
  20. Although it was quite hazy, I decided to get the telescope set up and then try to do some observing of Jupiter. I've always managed to time things poorly before and previously missed out on seeing the GRS. Anyway, half past eight, or there abouts, the GRS was meant to be mid-transit so I took my chance. Polar aligning the mount was a little tricky as Polaris was almost lost in the haze. I couldn't see it naked eye but it popped into view through the polar scope. After some tweaking on the EQ5's suspect bendy bolts I lined up on Jupiter and had a view at 200x (with my 5 mm ep). The haze helped a bit as this helped to calm down the brightness somewhat. The seeing was great and all four visible moons resolved as steady discs. The GRS was clearly visible, nicely salmon pink in colour, and delineated by a thin white band against the main band it nestles in. This main band had a number of white features within it appearing to trail behind the GRS. It was the best view of Jupiter I've had and it was certainly worth the wait - all two years since I got the telescope (which has spent most of its time pointing at faint DSOs).
  21. Attempt number 2 at processing Jupiter. Finding it incredibly frustrating trying to image with my current set up, so have invested in 'Making Every Photon Count' to help me decide what I should upgrade to! Composite image of Jupiter and 3 of its Galilean moons Canon 70d, 8" Dobsonian (prime focus and manually tracked) 1 x 30 sec video, stacked, for Jupiter I attempted eyepiece projection, but couldn't achieve focus... no doubt I am doing something wrong, but couldn't work out what!
  22. All set up to go with the sole aim of getting some Saturn images! To start off it was Jupes again to get some imaging done... The GRS superbly placed and looking Redder than a lidl tomato (subliminal advertising) After capturing some film it was time to properly align using Polaris and that wonderful on ya knees polar scope method!!! Boom!! three calibration stars and 'GoTo' whatever you wish for! Cygnus time - Check sheets and then give up and go and fetch Sissy Haas bible... 20 lovely doubles, not rushed just enjoyed and studied hard... working with my Starwave f/11 102 and for those difficult ones a 6.5 Meade HD and even with the 2.5 Revelation Barlow gave interesting views... 200x the recommended max mag on that Starwave, I squeezed more than that out of her. The stars looked round and colourful the companions sometimes hard to spot... But there's a great deal of satisfaction when you see them close by. I made some star symbol notes in the book when a true double of beauty made me smile, my top few were: Σ 2668 Superb 26 Gyg lovely 17 Cyg 19 Cyg Bright Red Ψ Cyg Σ 2687 Sharp 49 Cyg Faint 48 Cyg Wide H IV 113 Spot on (why did I write that?) 61 Cyg Nice Also - Σ 2760, 59 Cyg, 52 Cyg, O Σ 410, Σ 2705, Σ 2588, S 726, Σ 2578, 16 Cyg, δ Cyg So that's my haul for the night... By the time I had finished those it was 01:30 and cloud had covered what was left of Saturn. The great thing about that session was that I didn't have those long whiney scope movements around the sky, it was all within the constellation. I expect my neighbours with open windows were also grateful. Love that 102 f/11 Starwave scope.... A lot of the comments in Sissy Haas recommend a 150mm for some of the hits I made with my 102 so I'm happy... to get the colour is special as well... Not sure my alignment was that great because after entering RA & Dec the doubles were not always centered which resulted in me having to move towards the nearest double looking star a lot of the times. Didn't get -19 Cyg or T Cyg although I tried... Oh and on editing my images I notice I bagged both Europa and Io.... shame Jupiter disappeared behind next doors roof before the shadow made a transit! I've had to lighten one image to show the moons so beware you professionals

    Jupiter 6122

    From the album: Jupiter

    Jupiter 1st March 2013. 200 frames with 300P and Canon 7D
  24. After my first go with my mono asi120mm, tonight i used my trust hd webcam. Struggled against the wind and cloud though and thus the focus is a bit off. Need to build my arduino focuser aswell as it a bit of a phaff focusing a 150PL on a tiny chip. Any how equipment was SW150PL, Trust hd webcam, 2x barlow. Captured several 1000 frame video then stacked in registax 6 plus wavelets Forgot to add with moons Europa Io and Callisto
  25. Morning All, Last night I managed this image of Jupiter and I would appreciate your tips on how to improve it. Equipment was 200P on HEQ5 with ASI120MM and Televue 2.5 powermate. Captured in Firecapture beta. 60 seconds. 512x440. Gain 41. Exposure time 13.65. 72 fps. Gamma 26. Processed in Virtual Dub, Castrator, AS2 and Registax 6. Whilst content with the image for my first with the new camera, I know better will come. My initial thoughts are: 1. Should I have taken a 2 minute AVI or is 4,300 frames enough? 2. Is the main problem I am out of focus and should work more on this next time? 3. I notice a slight onion ring. Have I overdone the sliders? Your advice as always would be most appreciated.
