  1. It won't happen again for another 105 years and it's unlikely that anyone on the earth now will be alive for the next one, apart from maybe a few young kids/babies who were too young to see it this time. I was looking at the Iphone/Android apps to time the transit from around the world and reading about this type of technology (Smart phones) not being available just 8 years ago during the last transit. (Ironically the simulations worked, but the app crashed on the day!!) It's amazing how technology has moved on in such a short time. During the transit before that, we were barely able to perform powered flight, now we've been to the moon and people are living in space. So what will technology be like for the next transit of Venus? Maybe people will live longer by then, so our children might see it! Will this forum still be the same, or will there have been another software update by then LOL? I don't think anyone could have imagined the technology we have now a hundred years ago and it's hard to imagine what will develop over the next 100 years. I hope humans will work things out an not make a mess of it!
  2. From the album: Astrophotography

    We set up the telescope in Cabbagetown Park, Atlanta to share the event with our neighbors. In addition to creating this image, several people took their first ever look through a telescope, witnessing a rare planetary transit of the Sun no less. This was also my first time using the solar filter and observing the Sun through my telescope. ISO 100 1/125s

  4. A movie I've put together using the SDO AIA 304 feed on the www.helioviewer.org website. The version on youtube is better quality and there is a very nice flare at the start of the video
  5. The ISS was predicted to cross the Sun's disk at 15:53:29s on Wednesday. The event was visible in a 6km wide track near my location. Using a home made Baader solar filter on my SW 130 PDS and my DSLR with EOS Utilities I captured the moment, rather poorly. There are 2 GIFs. One is real time as the transit lasted a whole 0.55 seconds and the other is the same GIF slowed down a bit. With hindsight I could have got the image scale up but it was all a bit hectic.
  6. I'm getting things together equipment I'm going to need for the 9th May transit. I already have a Baader Continuum filter but need a solar filter. I have a Celestron C6 and a Skywatcher Startravel 102 and need to know which scope will give me the best view so I can get the right size filter. Martyn.
  7. 17 frame animation. Seeing improved during the session. Europa itself becomes easier to see. The shadow is easily visible.Skymax 180 7″ Maksutov-Cass at f30 (x2 barlow)Imaging Source DBK 21AU618.as 17x90s AVI 60fpsCaptured with FireCapture, Stacking in AutoStakkert Wavelets in Registax, processing and rendering in Photoshop CC2017-05-04 21:22 UT – 22:11 UT, Seeing: III-IV
  8. Seeing was mostly poor, but I am quite happy with how it came out
  9. I took the best ISS images captured during yesterdays transit and ran them through Registax 6 to produce this image I think there are few artifacts present from the processing but I'm pleased with it

    Jupiter GRS Transit

    The GRS transits the meridian at 6.02am Jupiter will be 20 degrees above the horizon at this point, with sunrise still nearly an hour away at 6.54am. Timings and altitude from London.
  14. Well, got my Skywatcher Startravel 120 frac all kitted up to observe the transit of Mercury on Monday 9th May. Whilst I normally use my smaller 70mm frac to observe the sun, I wasn't happy with the quality of the image I was getting when doing any solar views; there seemed to always be a lot of haze always surrounding the sun when viewed with the smaller scope, so thought I'd see how the larger frac coped with solar views, which after flocking all internal areas of it a few weeks ago, and also the inside of the end cap, thought it might produce less hazy images. And that is indeed the case. Rather than do a full size filter for the whole 120mm aperture, I rather opted just to put some Baader solar filter in the smaller aperture opening on the lens cap. I also made a small filter to go on the finder scope too. All in all took it about 45 mins to make both filters. Fixed the lens cap filter in place by glueing it inside the lens cap itself permanently. The finder scope filter is just held in place by just three elastic bands around the tube of the finder scope. Tested it out for a few hours today to make sure all work well, and that the glue I used didn't melt in any heat from the sun, so just now need a nice sunny day on Monday to sit and enjoy the views!
  15. I got my 1st transit with an image.
  16. Hi, even if there are much nicer images here I like to sum up my experiences, I guess it is still worth a read to compare and learn from my mistakes. I started to prepare the day before but was to lazy to test the equipment on site, so I just checked batteries and collected all parts. More than a hour before first contact I started to set up everything. I rolled out a cable drum to get power for several hours and the first thing I found is that the power adapters did not fit into the three plug sockets on the cable drum. Meanwhile the wind started to fresh up and did blow away my sunshade. Good that it does not hit anything of my equipment, getting sun cream it was only for me. Now getting a multiple socket. Found that ony adapter gives too much voltage which my motorized focusser did not like. Getting a battery. Setting up a sun shade for my laptop. Then I started to align the NexStar SLT Goto for sun. At least I did try... What worked a few weeks before did not work anymore. I entered 12:xx:xx time then PM and NO SUN IN THE ALIGNMENT menu... Dang, as european I also tried AM because that AM/PM is quite strange for me and errror prone. Checked the sun menu, enabled. Even tried to disable it. Then I realized (now only about 20 minutes to the first contact) that whatever I entered AM/PM the next try the time was at 00:xx:xx, so that stupid scope ignored AM/PM! No chance to get the sun in the menu for alignment. DANG! I was nearly so angry to ditch all that scope into the ground. The I took a depth breath and changed the time zome to 0 (UTC) and substracted an hour to the entered time, so it now got 11:xx:xx which works with AM/PM... Celestron get your firmware right! Now focussing which was a bit hard with only the few sun spots and bad seeing. I thought I did it right, but later the mercury was not that sharp as I wished. I decided to shot every minute bursts of 5 images at ISO 200 and 1/1250s exposure time which looked good on the laptop. Then my intervallometer failed. So I triggered the camera via USB from DigiCamControl. JUST at the first contact time clouds came. DANG. So I did miss a good part of the time between first and second contact, also still struggeling with the intervallometer. After I made a ok image of the second contact I was able to get the intervallometer back to work (note to myself: investigate!) and had firstly a bit time to relax. Posted a image to a friend who was connected via chat with me. After some time I found that the images on screen where not showing the actual happening which I can see through the DSLR finder. I tried to put the images on my NAS but that seemed to be too slow, so I did gat a big delay. I though it would have been a good idea, so I could get out of the sun and process some images on my Desktop PC while they are coming in. After changing to the local disk things worked better, but then I found that I had a copy image batch in DigiCamControl to make a copy to my Desktop and there my usual Backup tried to back it up via the network (WLAN) also. Which did saturate the network quite easy... I may have worked to save the images on the NAS without that, but now I was using the local disk. HOWEVER. My mount did not track the sun very well, and with my DSLR at 1500mm focal length there is not much room at the top and bottom borders, so I had to correct the FOV every few minutes. Maybe it was the strange workaround I needed to to for the alignment, or I did entered some wrong time (even did use solar tracking speed) or the wind gusts just did their bad. So I was tied to my laptop for hours in the sun. Man I was quite tired that evening :-) What else went wrong: During the hours I swapped the camera battery and rotated it a bit. Also during messing with my intervallometer bursts are stupid. Too many images, I thought I could stack the 5 images but in the end it was too much work or I did need a script (which costs time to write) I did not refocus dust on my sensor (I guess so. check the video below) before starting a big session set back the image counter in the camera to 0000 so that it will not wrap up and mess your named sequence try everything a day before, don't be lasy even more than an hour setup time can be to few whan things go bad derotation (look at the strange curve of mercury in the video, normal at Alt/az) for the images failed because of the small and unsharp sun spots neighbors cat came to check my equipment. walked across the keyboard, could easy delete all ;-) Location was in the south of Berlin, Germany. First contact 13:12:07 and because of trees I could image until 17:00 local time. So a few words for the equipment: Celestron Mak127 NexStarSLT AltAz Goto Mount, Astrosolar filter foil (for visual), Nikon D5100, DigiCamControl to liveview and get images from the SD, DIY motorized focusser and DEW heater control (not used here...), DIY intervallometer (Arduino based). Software: For single images I used FITSwork and GIMP (2.9.x 32bit/channel). For resequencing, cropping and quality estimation I used PIPP. For making the animations from the sequences, sharpening and encoding I used Blenders video parts and bits (http://blender.org). Here is a animation of all good images including some clouds, I needed to stop at 17.00 local time (utc+1). After all I am still happy with my results. No worries here, still like that hobby :-) Cheers, Carsten
  17. Hi all, I was lucky to have the opportunity - and the sky - to watch and sketch the transit. This sketch has been done at the beginning of the transit, showing Mercury at about 1320 CEST near the prominence at the eastern limb. Telescope: Lunt LS50 THaB600PT Eyepiece: TS HR Planetary 7mm Date & Time: Mercury transit time Location: Dusseldorf region, Germany Technique: Koh-i-Noor soft pastels and pastel pens on Daler Rowney Ebony black sketching paper Clear and sunny skies!

  18. Quick and dirty animation from last night. The least best images in the animation are due to tree branches partially obscuring Jupiter during the sequence. Seeing was pretty poor (Antoniadi IV,V) - making focussing difficult C11 on EQ8, DFK21AU camera, 25fps, x2.5 barlow, efl ~ 7m betwee 21:04 &21:55 UT
  19. Not as good a Jupiter as some high-end set ups are already getting but I did catch some transit action this morning.
  20. I was in Svalbard for the transit of Venus, filming with the Sky at Night team on the island of Spitsbergen. We had a few cloud issues at the start of the event but there were plenty of holes during and clear skies at the end of the transit. Here's a full white light disc...
  21. im going to be watching it with this as the weather for me looks too bad www.slooh.com its started 10 minuits ago, and they have loads of live feeds from all over the world!

  25. A still from the video of the ISS transiting the Sun at 12:38 today. One of the 13 frames the ISS is visible on captured with my 4" f11 refractor modified for Solar Ha imaging and a DMK21 mono camera running at 60fps High cloud hasn't helped at all but I'm quite pleased with the results. and a stacked image of the ISS using 10 of the 13 images captured the video will be online at Youtube and is currently being processed by their system so the quality will gradually improve and always viewing on the Youtube site is recommended.
