    Venus and Mercury, Oct 28

    At around 14.35 GMT today I observed Venus, Mercury and Jupiter, with my 127mm Mak SLT GoTo. Venus was a large, very thin crescent, trembly in poor seeing. Mercury was easy to see once I got my eye in, and Jupiter was easier to pick out with a red filter. Mercury and Jupiter are now not far apart. (7min RA 3 deg Dec.) The visibility of Mercury seems dependent on atmospheric clarity. On several days recently I looked for it but could not see it.
  2. The best time to see Mercury in the morning sky in many parts of the world, but unfortunately virtually on the horizon at sunrise from London latitudes.
  3. It was more than a year since I last saw Mercury. The clouds are relentless and there's no chance of a proper observing session with a telescope but I woke up earlier today (well, 4 pm!) hoping to finally see this, one of my favourite planets. Four thirty and yours trully Venus was very bright as well as Jupiter. I could also see the Orion Nebula, Pleiades, Hyades with the naked but looking directly overhead I couldn't see any Perseids although I was hoping there was a small chance of catching one of these. The first moment I saw Mercury was 04:46 and I could still see it without binoculars at 05:35 so I had almost an hour to see it rise and faint into the morning light. The air was warm, 14°C but it was a bit windy and the clouds were rolling on and off the northeastern view covering Mercury now and again. I made a few pictures but there's nothing spectacular to share as one would expect, the planet is just a faint blob. Still it was really nice to see Mercury again. I hope I have a chance to observe it with a telescope some time soon!

    Three planets visible in the western sky, after sunset. Left is Jupiter, top is Mercury, Venus below. EOS 450D (modded), 1/20, f/3.5, ISO 400, Canon 200m f/2.8L lens.
  5. Hi all, just in case you get clouded out tomorrow, or can't view the event itself because of work, these two apps for IOS and Android should help you observe it; https://appsto.re/gb/9Pjacb.i https://play.google.com/store/apps/details?id=com.ideorum.mercurytransit&hl=en Have fun!
  6. Here is some video I shot of the Venus & Mercury conjunction on the same evening I took the image. Watch out for the geese! Regards, Reggie

    1st Transit, 2nd Contact

    My first attempt at photographing a Transit and I decided to try for the 2nd and 3rd Contacts, but of course as those in the UK will know, the final phase of the Mercury Transit was clouded out. So, here's my attempt to capture "2nd Contact" using a Canon 600D (unmodded) at eyepiece projection with a Baader Hyperion 17mm, Baader Solar Continuum filter, Lunt Herschel Wedge and a Skywatcher ED80 DS Pro on a HEQ5:

    Mercury Transit

    This was probably my best effort... 900 frames at 12:28pm - earlier ones were battling exposure levels through the clouds! ED80, DBK camera, stacked in AutoStakkert then processed in PSCS5. Not a patch on some of the other images posted, but am pleased to have got this much!
  10. It occured to me that I should share with you the timelapes of this year's Mercury transit as seen from Czech Republic. The clouds have parted for some 20 minuts, allowing me to capture this timelapse. I shot it with a modified webcam, Baader 2.25x Barlow and UV/IR cut filter, using my former SW MAK 102/1300.
  11. 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

    Mercury Transit Images

    Hi, As the title suggests. Poor weather here, but it would be good to see other people's images! John

    Transit of Mercury

    I wasn't sure whether to post these in Solar Imaging, Planetary Imaging or Special Events so apologies if this is in the wrong place. Here are a couple of images of the Transit of Mercury. We were lucky with the weather which allowed us some clear views until about 4pm when cloud and then rain ended the session. Both images are taken from 1000 frame video processed in PIPP, AutoStakkert, Registax and Photoshop. Equipment: Celestron NexStar 127 SLT Skywatcher EQ5 Mount ZWO ASI120 MC imaging camera
  14. 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.

  15. 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.

    Mercury Transit 2016.05.09

    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

  19. Woke up early this morning and thought i'd try to capture the 3 planets before the Sun joined the party, probably be cloudy tomorrow Should have got there earlier but it was a Sunday lol Was very very cold icy car, numb fingers and toes Spica is visible top right as well.

    Mercury at Elongation

    Here is a quick shot of Mercury using my Orion Deep Space Video Cam II with my Orion 127mm Mak. The turbulence was pretty fierce because of the low elevation, but you can still make out the phase (I hope): Enjoy, Reggie
  22. After heading up to the highest point around I managed to spot all three tonight in a lovely triangle. Massive bank of cloud low down. Venus popped into view closely followed by Jupiter, then a lucky break between the cloud bank and all three. Canon 30D, Helios 135mm f2.8 stopped to f4. ISO 100 at 1/8s Thanks Jamie

  24. 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!
  25. 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
