  1. 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...
  2. 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
  3. 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/
  4. 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
  5. After one or two failled attempts I finally managed to image Jupiter plus its Great Red Spot, Ganymede and its shadow. Taken using an unmodded Toucam and an IR blocking filter attatched to a 200 mm Skywatcher Explorer with a 3x barlow and 1227 images stacked. I had the added problem of Jupiter going behind the trees during imaging, where I am there's trees everywhere and I only had a small area to place my telescope, I just can't avoid them so I was having to deal with an image that was darkening then brightening for most of the time, but one good thing about winter is all the leaves have fallen so I can see through the trees. Also I couldn't see the northern sky so it was just a case of pointing the mount what I reckoned was north, so constantly having to press the direction button to keep the image in the centre of the field

  9. Seeing was mostly poor, but I am quite happy with how it came out
  10. Jupiter and one of its moons, Ganymede. Jupiter season has well and truly started now with Jupiter rising just after 1:30am, and it's close enough to Earth now for details to come through 1,000 frames processed in PIPP, Registax and Photoshop Equipment Celestron NexStar 127 SLT GoTo AltAz mount ZWO ASI120 MC imaging camera
  11. 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.

  12. 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.
  13. 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
  14. Jupiter and from left to right, Ganymede, Europa and Io. This is 2 images combined, one exposed for Jupiter and one over-exposed for the moons. Skywatcher 200p Philips 840K flashed to SPC900 Skywatcher stock 2x barlow. Jupiter 18th September 2012 by Paul S Wharton, on Flickr Paul
  15. Not as good a Jupiter as some high-end set ups are already getting but I did catch some transit action this morning.
  16. From the album: Astrophotography

    Taken from our front yard in Atlanta, we only have a small window into the cosmos through the tree cover. In order to capture Jupiter at Opposition I had to wait until 3am when the planet came into view. ISO 100 1/20s

  18. So it all went horribly wrong three times... Alignment!! how can you mess up alignment three times? Well, when you are in a hurry and have an pre planned observing list that must have been prepared for targets around at 4 in the morning!! Objects currently below the horizon... Argh I must learn more star names to make alignment easier!! Anyway, I want to let you know that despite some frustrations my advice is you should never give up on a clear night! Today for the first time in ages I was inspired by 'Nick of the Swad' to plan an evenings observing... I created a list of targets and for once decided to try my rifle finder on my Starwave 102 (relevance later) When finally aligned I picked M13 as my first target... Lovely! surprisingly detailed I thought at high mag... Then it all went wrong again, I put in an NGC target and the scope pionted below the horizon.. so fed up was I that I decided to spend some time on Jupiter instead of my target list (Nick had recommended a moons of Jupiter app so I thought I would check it out) Ok next door have a large Conifer and Jupiter was to the left of it so I used my red dot finder and hit the target perfectly... It appears the scope/mount was still tracking correctly so no rush plenty of time to observe. I read earlier today that a blue filter would be good to view Jupiter, so I set it into a BST8mm and concentrated on the nice crisp banded planet and moons. Note!! this is why you should never give up! I just witnessed a transit of Ganymede across the edge of the Jupiter!! At first I thought it was just a trick of my eye but I could clearly see the moon and a shadow on the bottom/top edge. I checked the moons of Jupiter app and sure enough this was indeed what I was watching. Unbelievable, I got so excited out there I can tell you... Almost as excited as I was when I first saw the moons in a skywatcher 114p years ago. I realise the transits must happen a lot but that's the first real clear one I've witnessed, amazing... Just had to write it down to share. How wonderful was that? The blue filter, the red dot finder... The messed up alignments all lead to that event. Thanks to Nick for the tip, and thanks to my incompetence, otherwise I suspect I would be still out there with my target list... Not sat here basking in the glory of what for me was a mind blowingly satisfying moment...
  19. Amazing coincidental transits of the Great Red Spot AND Ganymede on Jupiter shot using my Orion Deep Space Video Camera II and my Orion SkyView Pro 180mm Mak around midnight last night (April 22). Ganymede can be seen casting a shadow along the northern limb. The GRS can be seen roughly near the center of the planet. "Intrapsychic Conflict" is introduced as the musical landscape, not unconscious turmoil, lol! Enjoy! Reggie
  20. This shot was taken in Regents Park, London at 22:07 and shows the Jupiter with its four Galilean moons: Ganymede to the right of Jupiter, Callisto on the immediate left of Jupiter, Io a little further to the left, and Europa on the far left. The shadow of Ganymede can be seen on the left side of the planet as it begins its transit. Jupiter is getting further and further away from us at this time of year but it is still showing a surprising amount of detail.
  21. Last night was a beautiful night to image Jupiter and it's moons. After I took low exposures to get more detail on Jupiter (1/625 seconds) I bumped it up to 1/10 seconds to get the moons. I took the images with a Celestron 114 LCM 4.5" reflector and a Neximage Burst as the camera. The image is 2000 frames and was stacked and processed with Registax 6.1. Thank you and clear skies! Adam
  22. From the album: Solar System Objects

    This picture of Jupiter was imaged on one of the clearest nights I've ever had using a NexStar 8SE and a Skyris 618C. The night was so clear that even the view through the eyepiece revealed details in the atmosphere and the GRS like I've never seen before. After imaging Jupiter, I stacked and processed the Planet and the moons separately concentrating individually on the detail in each object.
  23. Hi all, I was out on the 28th October (Sunday) waiting for the Great Red Spot to appear on Jupiter. As I was watching the GRS move across the disc I noticed what I thought initially was a speck of dust or defect in my eyepiece. My initial panic subsided when it moved and I realised I was watching a moon shadow transit! So I was treated to 2 events that night but it's been annoying me that I didn't know what moon it was. I'm having trouble setting up Stellarium to give me reliable data (I have location, altitude and time set up correctly) for Jovian event predictions. I much prefer a bit of paper anyway and I found this on Sky and Telescope web site; it gives the start, midpoint and end of all Jupiter moon events. Hopefully someone will find it useful if you haven't found it before http://media.skyandtelescope.com/documents/JphenTab2012-2013.pdf According to this it was Europa masquerading as dust!
  24. Here's a capture of Juptier, Ganymede and Callisto taken just after midnight on the 5th of December. Best regards, Pete
