  2. Ok, maybe not as dramatic as the title would suggest but still Santorini is a geo-active volcano system so I'm going to claim that one. So as some of you may know we have just returned from holidays in Crete and went to Santorini for the transit, the whole place was spectacular. Truly a worthy place for witnessing such a special event. We witnessed some great sights too while we were there, the rising of a near full blood red moon and the dramatic sunsets but that's for another thread possibly. We stayed in a hotel villa high on the rim of the caldera and had a perfect view eastward over the ocean, the weather leading up had been perfect and the morning before I had a succesful trial run in clear conditions and had everything worked out. Settings were honed, best location found etc... However, that evening some disturbing developments were afoot which left me feeling a bit uneasy. You guessed it, cloud. It was the type of cloud that only forms at the top of mountains and nowhere else, lenticular I think. So to my disgust this was the scen that I awoke to in the morning. Unbelieveable, there had not been a cloud in sight for are whole trip or the days after. Thankfully though as you may be able to see(I do have better pics of the effect) there was a thin strip of clear air between the horizon and the cloud which was situated right over my head, although at the time I wasn't sure how it was going to play out. So it was now a waiting game to see what would happen next. Then at precisely 6:02am local time a first glimmer of orange began to peek over the horizon, YES!!!! I was going to be able to see it. My first few shots however were way out... the change of seeing had dramatically changed the settings I had figured out a day before and this played havoc throughout the transit and my plans. But still I had some degree of success and I am thrilled to be able to of captured and share with you some of the photos I took. Santorini Transit by Jarrod Bennett, on Flickr I do have some white light pics as well which I'll post when I get around to checking all the SD cards. There was a good 30 min or so chunk of the transit that I missed due to the clouds as the Sun got higher but it reappered towards the end so I'll go through it all and see what I can come up with. It's also worth mentioning that the Polarie performed reasonably well on it's solar tracking rate too. All in all I'm ectstatic to have seen such a special event. Jarrod.
  3. Just watched this full transit video from SDO: http://venustransit.gsfc.nasa.gov/data/kiosk/dataset/Venus_AIA12s_304Track/phase/track Oddly enough, if you look carefully, you can see the surface features of the sun through Venus' disk! Anyone know why this might be? I have a couple of ideas, neither of which I am confident about: 1) The CCD picking up the image is retaining some energy from earlier images, causing a ghost on the CCD. My main problem with this idea is that there is a good amount of time (over a minute and a half) between images, so presumably, any ghost heat on the CCD should have dissipated? Aside from this, I have no idea whether residual heat on the CCD would cause such an image. 2) Radiation from the sun at certain wavelengths is passing through Venus? As I write this, I realise how silly it is - any form of radiation (neutrinos only really) that could pass through an entire planet, would also presumably pass straight through our CCD. So apart from that I have no idea. I'm certain it's something fairly mundane, but interesting nonetheless! Any thoughts?
  4. Hi all, the weather wasn't promising but I thought I would stay under the rain and take the chance. At sunrise, I started shooting without any filter (humidity and clouds were enough as filters) and I'm so happy I was able to capture Venus passing in front of the sun :D Click to enlarge:

    Venus 20.04.2018

    From the album: Lunar and Planetary Images

    Venus imaged during the afternoon of 20.04.2018. Although imaged in broad daylight, the very short exposures required, just a couple of miliseconds, means the sky looks black. Such short exposures are required to prevent the image over exposing as Venus is so bright. Celestron 8SE and QHY5L-II monochrome camera with Celestron LX 2 x barlow. AVI stacked in Registax with minor adjustments in wavelets. No post-processing other than a slight crop.

  11. Hi All, I took this picture by coincidence while trying to take photo of a single cloud on the sky. Is this Venus? Thanks.
  12. Luckily had a really clear evening with no clouds on the western horizon I'll try to catch the Venus- Uranus conjunction too at the end of this month
  13. 3rd June 2015 Equipment: NexStar 8SE 18:16 - 19:30: Venus was approximately 30 degrees above the west western horizon. Bright and unmistakable. Through the 13mm TV it was a bright creamy white half phase with a hint of markings along the terminator extending about a third of the way toward the edge. Markings faded out toward the north and south poles. Tried imaging at F10 & F20 using a mono CCD DMK21au618 through IRPass 685nm, Neodymium and UVenus filters to combine as RGB. IR Pass and Nd were bright in both focal lengths but UVenus was very dim had to be pushed to full gain and shuttle slowed down to 1/7 f20 and 1/15th F10. Between 19:30 and approx 21:00 Saturn was only rising, about 45 degrees in the east and was moving behind a large tree in east obstructing view. Add to that that sporadic clouds were moving toward Saturn from north-west so I waited to see what will happen when Saturn rises above the tree blocking the view. Luckily the clouds cleared mostly when Saturn was in prime imaging and viewing position. 21:00-23:00: Saturn was a sight to behold. The seeing was one of, and most likely the best I have ever seen. Using 11mm TV the view was sharp, bright and detailed. 7mm just like with 11mm TV sharp and detailed. 5mm again sharp and detailed. 11mm 2.5X PM sharp and detailed. Sharpest and biggest most detailed view. 5mm 2.5X PM started to go soft but still this was at 1016X mathematically but in reality 700-800x since the 2.5X PM seems to magnify less then the 2X Barlow... Due to length of tube. Color was visible, so were clear cloud bands in the atmosphere along with the details in rings. The Cassini division was crystal clear all the way around the ring, only covered by the globe behind the planet... At times I thought I saw the Encke division at 460x (11mm TV & 2.5X PM) perhaps it was wishful thinking since imaging did not reveal it at F20 or F50, but the view was still and crisp. I spent about 90 minutes+ just staring at Saturn, couldn't pull myself away from the eyepiece. 23:00-23:30: The Moon was the last object observed and imaged. Just past full moon, the side with shadowing was crisp at all powers used from 180X - 406X. It's been a while since the moon got some attention, last time was during the two Saturn Occultations last year. I imaged using f10 and DMK21 through IR Cut... Created a 10 plate mosaic of the contrasty edge. Very cold, couldn't feel my hands by 23:30 when I packed up but was a great night of imaging and viewing. MG
  14. OK I admit, I'm click bating just a little with that title But on a few occasions recently when I've been observing Venus I've noticed a light feature towards the north pole of the planet. Obviously it's not ice! (Venus is roasting hot and you'd never see the surface through the clouds anyway) But it does look like a white cap perhaps with a darker band below. I was wondering if anyone else had ever seen this? I'm thinking 3 possible explanations (You'll note lunacy is not among them, though clearly it can't be entirely discounted ) (1) Some sort of polar cloud vortex ? (2) The atmospheric dispersion creates a slight blue fringe at that end of Venus and that somehow leads to the illusion of a bright spot ? (3) A combination of air ripples (seeing) and some sort of psychological predisposition to "expect" a feature there. Perhaps rather like the Ashen light which may be a predisposition based on our experience of earthshine on the Moon (though it may be a real physical phenomenon too - the jury's still out as far as I know) ? I had a go at photographing it with a DSLR (I'm not an expert astrophotographer!) and it's certainly not as clear in the photo as it appeared in the eyepiece but perhaps there's a hint of it - though not much of one! As an interesting aside, I came across this 1968 paper that does appear to suggest the presence of physical ice on venus - Just shows how far we've come in our understanding of Venus since then! http://science.sciencemag.org/content/159/3819/1097
  15. A shot of Venus taken from Regents Park, London. At the moment Venus is remaining in the night sky until quite late at night which is unusual for a planet so close to the Sun. In this shot Venus is 60% illuminated.

  17. Hi All, I had a go at imaging Venus last night. I took an AVI and Registaxed it just now. Is that banding I can see, running across from 2 o'clock to 7 o'clock? And yes, it is Venus, not Jupiter! Sorry for the small size.
  18. Hi all, before going comet hunting tonight I went and found a nice vantage point to observe tonights conjunction of Venus and Mercury. I believe I read they were around 1degree separated. They look great hanging low in the dusk sky and Mars was also visible higher up and more southerly. I took quite a few images but this 4sec ISO100 shot was my favourite.

  19. First, I would like to say,.. great new look Stargazers Lounge! I have been wanting to write this for some time now,.. Believe me! Unfortunately, I'm finding it harder to stargaze and report my findings these days. The exam period combined with the extended hours of daylight make it hard for me to make my way unto my porch with the necessary darkness to see anything worthwhile. However, I had been waiting impatiently for this day to arrive for awhile now. It was introduced to the world weeks ago (even if I had known about it for some time) as the astronomical event of the century. This was no fancy name since it would take over a hundred years for this phenomenon to happen again. At first I didn't want to be too excited since I knew that my success in seeing anything would depend on the weather. When the long range forecast seemed favourable, although a long shot since such predictions are rarely accurate, I extended my efforts to prepare myself. I researched the subject extensively: How could I experience the transit of Venus safely (for both myself and the equipment used). All sources pointed in the same direction: I was not, under any circumstances, to use my telescope since the aperture at 10" was too great. To point it at the sun would result in damaging my oculars and secondary mirror. I came across a project which greatly appealed to me. It involved binoculars, a tripod and the ability to project the image of the sun unto a white piece of paper. I would like to thank this forum for their many helpful suggestions during the preparation for this event. For this to work properly, I had to add some shadow since the beam of light would not be seen in broad daylight. I therefore added a piece of cardboard paper around the lenses and covered one of the eyepieces for better viewing. It was proposed that I line an extra box with black paper to provide the extra contrast I would need for a pristine view. It was also suggested by some that I could indeed use my telescope if the aperture was reduced to 2". This could easily be done with a piece of plywood but,... I resisted (well actually, the correct word for it was that I was insecure). I settled that night with my binocular project and waited for the transit to begin: I had trouble sleeping the night before since I had important plans for school and was nervous / excited as to what the next day would bring. At 4:00am I gave up trying to sleep and made my way to the kitchen where a waning strawberry moon (the full moon was the day before) greeted me. It was at that very moment that I knew that everything would turn out fine. In the end, my responsibilities regarding the final examinations at school went extremely well, promising me a successful evening. Well, not everything went that smoothly at first but,.. I had to believe that it would all work out. I waited for the transit to commence by watching a countdown online and made my way outdoors. Two of my students had already made their way to my house for the show. I tried in vain to see it but all the projection revealed was a fuzzy glow. Not a speck of Venus could be found. I simply could NOT focus! Frustration set in when my students decided to leave because Venus was giving us a "no show". It was at that moment that my eyes turned towards my telescope. Some had said on this forum that it could work and my time was running out since the sun was threatening to set over my neighbour's house. I grabbed for my telscope cover which had a hole of 2" already prepared and set up one last time. My husband helped me align the scope and take the picture since it was hard to hold the box and do all of this at the same time. Once we saw the projection of the sun, we focused the telescope and there it was,... It was Venus! I admit it,... I cried. Steven and I took pictures as the sun slowly disappeared behind my neighbour's roof. It was a shadow, a dot,... but it was my dot, my capture, my experience! It makes us wonder though: For a handful of hours (give or take a few), the world had caught a fever that had united them with one quest: To experience the transit. In one evening and one morning (depending which area from earth you viewed it from) there was one goal. It had nothing to do with religion, politics, debatable issues, money,... It had everything to do with experiencing a small something that was beyond our immediate grasp. Thank you Venus for sharing your journey, vision and a certain hope for the answers / questions of tomorrow! Isabelle
  20. 5:30am for me... my first solar pictures ever! Well worth the effort... I don't know still how to stack pictures or what is the right way to process them... I'm starting to read about it now, i hope i'll manage the basics soon! Enough of talking.. here are my humble results: I regretted not having the adapter to use the eyepieces with the camera... but I still enjoyed! Cheers, Rui
  21. 5:06am No sign of Venus here... hang on, that's not the sun is it. Wrong direction! 5:11am The view looking in the right direction. Cloud... 5:22am I see you! 5:27am Although it had moved away from the low cloud, it moved into another band. 5:31am At last, a clear shot. 5:39am Making contact on the way out... 5:42am The kit in action. 5:54am Barely visible still... the sun went behind some thin cloud after this so I didn't catch the exact moment Venus disappeared. Kit used: Canon 7D and 600D. Canon 100-400L and 15-85. Baader solar film ND5 on the 100-400L. I also took some video I might sort out later. Very tiered now. Stayed up to past 1am watching the Nasa feed. Woke up just before 4am... I did plan ahead and took the day off work. Next stop: bed.
  22. After A Very Loooooooooooong Time, This Is My Try At The Transit, With My Panasonic Fz 28 And A Sun Filter (No Telescope)
  23. Here is a short clip from the live feed I was doing from my backyard telescope is the San Mateo. I had the live feed on UStream and started it at 3pm and ended around 7:20pm PST. It was windy so thats one of the reasons it was jumpy. [media=]
  24. 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!

    Harlem Planets

    From the album: Astrophotography

    This is an old photo shot with my 40D in 2012. This is from my fire escape in Harlem, Manhattan, March 2012 of the conjunction of Jupiter & Venus on the night of their closest approach when they were only 3 degrees apart in the sky. Just goes to show that you can do astrophotography even in the most light polluted of locations. Here is a celestial event as seen from "the city that never sleeps." Don't let you location get in the way of appreciating the night sky. ISO 1600 1/4s f/4.5 18mm
