  1. Nicks old 130p heritage scope out cooling ready for Callistos transit such starts in 30 mins... Might try Mars as well. Mark
  2. Callisto 1.5.17, 22.59. Cropped from a 480x480 AVI of Jupiter and processed on its own as an AVI, this way means it will be stacked on the moon and not the planet= no trail . I used Vdub to crop the AVI and enlarge then put it though PIPP to center, AS!2 to stack and Registax for sharpening & wavelets. 10" dob x3 barlow, asi 120 mcs camera hand tracked.
  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/

  6. 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. Thanks for looking. Jupiter & 4 moons [2016.02.11] - composite image by 1CM69, on Flickr Jupiter & 4 moons [2016.02.11] labelled for identification - composite image by 1CM69, on Flickr
  7. From the album: Time-Lapse

    An attempt at creating a time-lapse animation of Jupiter and its moons. Here you can see Callisto occulting Europa before they disappear off the screen and they are followed by Io. Shots were taken at intervals of two and a minutes on the night of 6th December 2014. 104 frames played back at 24 frames per second. Each frame made from a 500 frame video. Processing done in PIPP, Registax and Photoshop CS6.

  8. 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.
  9. Jupiter with two of its moons, Io, closest to the planet, and Callisto on the far left. Taken on April 9th 2015 in Regents Park, London. Processed in PIPP and Registax.
  10. Hi all, been pretty quiet lately due to shoddy weather! Finally spotted about 5 nanoseconds of reasonable seeing here on Saturday night, so managed to get a bit of a Jupiter family portrait before the atmosphere boiled over again. Sadly couldn't stay awake long enough to wait for the GRS to appear (next time) - but happy to get what looks like some sort of detail on Callisto (or is it just exposure anomaly...ho hum) Celestron 9.25" SCT on EQ6, DMK 21 camera with RGB filters. Separate exposures per object to get the best image I could for each. Cheers Jim
  11. During the early hours of September 9th, I set my telescope up for the Google hangout / Virtual Star Party event, where amateur astronomers around the globe can share their view of space with the internet. This event is a regular occurrence, with PhD astronomers also joining in, providing their expertise, commentary and humor. Unfortunately the event was cancelled as most of the amateur astronomers had cloud cover. Fortunately for me, clear skies prevailed. Jupiter makes for an exceptional view in the night sky, but that morning I had the chance to photograph a rather special moment. The Jovian moon Callisto was transiting Jupiter, casting a clear shadow over the cloud tops and as an extra treat, the Great Red Spot (GRS) was also facing towards Earth. This video was produced by taking a 60 second capture roughly ('very' roughly) every five minutes. Each video was then processed and stacked in Registax and sharpened in Photoshop. These images are then "played" forwards and backwards in this video. From this you get the motion of Jupiter's rotation, and the transit of Callisto. I hope to make a much longer video of Jupiter's rotation, as the planets ten hour day means you can see almost all of the surface, but currently it is barely over the rooftops by 4am, I'd need a much earlier start to capture more footage. The following is the technical spec of the equipment used to capture this video. Hardware: Meade LX90 8" SCT (Focal Length 2032mm, f/10) Eq Wedge, Drift Aligned, No Guiding Meade 3x Shorty Barlow ZWO ASI120mc (10ms Shutter, Gain 100, Gamma 50, ROI 448x448, FPS 100) Processing: PIPP: Centering, Quality Ordering, GRGB Debayer Registax: Alignment, Limiting (Best 80%), Stacking, RGB Balance, RGB Align Photoshop:Sharpening, Saturation, Curves, Enhancement of Callisto Conditions: Clear, High Humidity, 10c, Suburban Light Pollution, Infrequent Gusts around 7mph
  12. 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

  14. Jupiter just after a transit of Callisto. Taken just after midnight on March 18th, the shot shows from left to right the moons Europa, Io, and Callisto. Callisto's shadow can be seen on the top right side of Jupiter. Image made from a 1000 frame video Captured with FireCapture Processed with PIPP, Registax and Photoshop. Equipment: Celestron NexStar 127 SLT GoTo AltAz mount with homemade wedge ZWO ASI120 MC imaging camera x2 Barlow
  15. 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.
  16. A quick processing of one of the shots from Jupiter's triple moon transit on the morning of Saturday 24th January. This first shot from 4:30am shows Europa, Callisto and Io heading towards the planet (Europa far left). The shadow of Callisto can be seen on the Planet's surface. Unfortunately it wasn't possible to get an animated sequence of the transit because Jupiter dropped behind houses at 5:50am just as the show was getting really interesting and one or two computer problems caused some delays. Actually it was amazing to be able to get anything at all...the weather was dreadful most of the night with torrential rain which stopped at about 3am and the cloud vanished an hour later leaving clear sky but not much time. Still, we got 20 shots over the hour. I'm looking forward to seeing how the others come out now
  17. 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
  18. 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!
  19. Here's a capture of Juptier, Ganymede and Callisto taken just after midnight on the 5th of December. Best regards, Pete
