  1. I'm currently on my annual leave in Italy and the sky has been clear all day with no air turbulence. The telescope is out - of course - and I managed a session before dinner. I thought about sharing some photos taken with my phone and a couple of sketches.

    Jupiter - 17Aug2019

    From the album: Solar System Objects

    Jupiter imaged on 17 August 2019 using a C8 SCT, Skyris 618C at f33.

  3. Hello All, Sharing with you my best images of Jupiter and Saturn for this year. I haven't had the luck of a High Pressure system with no wind speed yet, but on the 17th it was as close as I had for planetary this Jupiter/Saturn season. Not my best images of the gas giants ever but ok IMO. I'm happy to see that the GRS seems to be repairing itself, last time I imaged Jupiter, the border around the GRS looked like it was breaking up so perhaps it'll be around long enough for my kids to see in the eyepiece. Captured at f33. Images consist of the best 15% frames from 13x60sec @ 60fps for Jupiter and 13x120s @ 30fps for Saturn, derotated in WinJupos. Clear Skies, MG
  4. Hey all, I cannot believe my luck. I was out on the 31st July practicing imaging Jupiter and Saturn with the my new ADC and ZWO Asi224MC. All of a sudden the ISS started to appear from the South West heading East. I quickly released the clutches on the mount and followed the ISS the best I could with the finder scope. Everything was set in sharp cap for the Jupiter capture, ROI was set to 320 x 240, 2x barlow plus ADC. I could not believe it out of 6500 frames I manged to find 13 frames, which I stacked. Second bit of luck, PIPP said it could not find an object, so I turned the option off and it ran without errors. The hero was AutoStakkert which sorted the frames to the front of the ser file. Composite of 3 images from my night:
  5. Hey all, I just started imaging the planets again after a long break. I have just purchased some new equipment a ZWO ASI224MC and skywatcher ADC (replacement for SPC900). I have read a lot about image quality depending on the height of the planets. The image shows top row images I took in Dec 2012 SPC900 ( looks like the world did not end ) and bottom row July 2019 224MC. Would the difference I am seeing in quality be down to just position or am I not setting the new camera correctly? Thanks for any more image examples or help.
  6. Hi everyone, Can anyone confirm (or refute) - have I imaged Ganymede and Europa in orbit around Jupiter or is that just wishful thinking? (Only equipment used was a Lumix G7 with 150mm zoom lens - effectively 300mm with 2x crop factor - and of course a tripod). It appears to be the case and yet I can't quite allow myself to believe it... Thanks from an old newbie.
  7. Another attemp on Jupiter from me, a novice on astrophotography, lol. But this time image is taken using Orion Shorty Plus 2X Barlow. Image is still captured using Canon 60D, prime focus on CPC1100. Stacked and processed using Registax and Instagram as usual Two attemps on Jupiter which produce more or less the same image. Seeing from the image, I think this barlow degrade image quality quite significant. Please advise if any. Thanks Cheers
  8. Hello Astronomers, After imaging quite a detailed image (for using an 8" SCT) of Jupiter last year, I was hoping to match or exceed it this year, but I can't quite get that atmospheric condition which will allow me to capture those fine structures. Attached is my best Jupiter this year... I would have thought I'd get more detail since Jupiter passes overhead near zenith... I guess I just have to keep trying and hope for that super still night. Clear Skies, MG
  9. An image of Jupiter taken late evening, 27 June. Not as good as some other people's efforts, but one of my best Jupiter images this year. The planet was low (around 15 deg) and the seeing was not great. CPC800, ASI224MC, ADC, captured in Sharpcap, processed in Registax6. Best 20% of 5000 frames IIRC. One of the images here is a random raw frame, to show what I had to work with. Io should be visible on left in the processed image.
  10. An image of Jupiter taken early morning, 16 June. Not as good as some other people's efforts, but the planet was low (around 15 deg) and the seeing was not great. CPC800, ASI224MC, ADC, captured in Sharpcap, processed in Registax6. Best 15% of 7000 frames IIRC. One of the images here is a random raw frame, to show what I had to work with. Ganymede should be visible on left in the processed image. GRS coming into view on left.
  11. Just got 2nd hand Celestron CPC1100. Tried to take Saturn and Jupiter image with Canon 60D, prime focus. Took 1.5 minutes (Saturn) and 2 minutes (Jupiter) videos, stacked and processed with Registax and Instagram (lol). Hope to get better image later.

    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.

    Jupiter - 127Mak-Cas - F12 - AS!2 - 840 Stack - Denoise / Sharpen - Histogram Stretch - RGB Rebalance - Midtones adj This was taken on the 22nd at about 2C did about 1400 images, but due to clouds and poor seeing has been reduced to 840. I read a great post which helped me a great deal in getting a better image. http://stargazerslounge.com/topic/184821-beginners-guide-to-stacking-planetary-images-with-autostakkert2/?hl=+registax (Thanks James) Going to continue processing and see if I can get this better.

  21. 21 of June 2017 / 22h30 UTC+01:00 / Stargazing Conditions: 88% So, I crammed all of my new acquired stuff together and went to the darkest place I could find near my town. It's a mere 5 minute drive from my home. As I set everything up, I tried to wait for 20-30 minutes to give the 'scope a chance to acclimatize but I really couldn't! Jupiter I looked west south west to find Jupiter, pointed my finderscope at it and I was amazed by how clear the image from the 'scope was!! I had a 5 minute stare through my 25mm BST eyepiece where I could distinctly see the two belts, the north and south equatorial belt. As clearly as the belts were also three of its moons were, namely Callisto, Europa and Io, although Europa was quite close to Jupiter. The color was also great and the view, simply mesmerizing! I then switched to the 15mm BST eyepiece. First I was a little, let's say disappointed, but not that strong, by the magnification, and immediatly switched to the 8mm BST. To my surprise I wasn't convinced by the view either... So I decided to get back to the 25mm and calm down and enjoy the view as I clearly was getting hasty. As I started over, I remembered some words from a friend of mine who told me that watching the stars often comes down to 50% of actually seeing the stars and 50% imagination and concentration. So I tried the 15mm a second time and... I was hooked. I could now clearly see eight different colors and belts! I'm not quite sure what it was I saw, except the north and south equatorial belt, but I will have a look at some Jupiter maps and educate myself about the planet's surface. This will help in better understanding and watching next time, the case given that the seeing is as clear as it was that night. With the 15mm eyepiece Europa was now very distinct from Jupiter. I couldn't manage to get more detail out of the 8mm eyepiece, everything just got a tad bigger and a little fainter if my impressions were right. After good half an hour of watching the delightful planet and its moons I sat down and searched for Saturn, which was south not very high above the horizon. Saturn I switched back to the 25mm eyepiece, pointed my viewfinder at Saturn and peaked through the eyepiece. What a marvel! I clearly could see some colors on the surface and easily distinct the ring from the planet itself. As I switched over to the 15mm eyepiece, the separations on the planet's surface became a tad clearer and the ring/planet separation obviously bigger. I encountered the same problem as before of not knowing what I was looking at, which bothered me a little. I have to do a little homework here and get myself started with some fancy vocabulary. Milky Way All in all it was a marvelous first light experience and I clearly have to learn the stuff I'm looking at, but I think that's just me and my endless thirst for knowing things. I randomly gazed through the skies at the end, beeing absolutely overwhelmed by everything I saw. Furthermore, I simply was flabbergasted when I ran across the milky way in the north east... There were so many stars I couldn't see with my bare eye, but only with the 'scope (which made aiming with the finderscope a nightmare... How do you guys do that really?!). I'm glad I acquired the Skywatcher Skyliner 200P with the eyepieces. It is one of the best things I got myself and I think I will have a lot of fun with it and furthermore learn so many new things. Thanks for reading, Abe

    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...
