  1. If you ever come to Sweden there is an interesting model of our solar system here, it covers the whole country. They started to build this model in late 1990s and my teacher in astronomy prof Gösta Gahm was one of them who started this project. In May 2019 I was invited by Gösta to participate of the installation of Jupiter version 2 at Sky City in Stockholm. I took som photos and did a report from that event. If you find it interesting to read you find it here: http://www.astrofriend.eu/astronomy/astronomy-articles/sweden-solar-system-jupiter-2019/sweden-solar-system-jupiter.html ps. There are of course a lot of other interesting things to visit and see in Sweden! /Lars
  2. Greetings, I thought I'd share with you all this little arty farty collage I made of the moon and some of the planets: Jupiter, Mars and Saturn. All the photos were taken by holding my iPad to my 8inch dob. They were then processed on my iPad and put together on Instagram. Not amazing I know but I was quite chuffed considering my technical limitations. clear skies, Thomas
  3. Hi, This is probably a very obvious question. If I'm standing outside at about 51 deg N. I had always thought that North was towards Scotland, but actually, it at an angle above my head. This seems right once I realise that I am halfway up a globe, so N is not the tangent of the globe where I am standing but at another angle, parallel to the axis of rotation of the earth. Similarly, the sun is in the South at midday, so I have to look South to the ecliptic. Does pretty much the whole solar system lie on the ecliptic? The Moon is to the South, as is Mars and Saturn, as was Jupiter when I could see it, so is everything in the Solar system there? Finally, during the seasons, in the Winter the Sun is above the tropic of Capricorn, so is the ecliptic further South during the day and at Night the objects on the ecliptic should be easier to see (higher above the horizon), and during the summer the Sun is on the tropic of Cancer, so the ecliptic is further South at night and harder to see (lower above the horizon) and also more difficult because of the short nights. I recall Jupiter was so bright and high it was almost casting shadows in April (2 months before the solstice), as was the Moon but now two months after the solstice, I can hardly see Saturn above my neighbour's trees, nor the Moon. Is this not right? What have I not understood correctly? Back off outside now, Regards Steve.
  4. Found an old (apparently USA model) celestron C8 SCT a while back, its a bit hit n miss with collimation and the optics - (some very strange star test shapes :P) but when it works it works well Here is a couple images from a couple months back. Thanks for looking. This particular night seeing was reasonably good, and collimation wasn't too bad either. Celestron C8 / ASI120MC / 2X barlow - captured in sharpcap2, stacked in autostakkert!2, wavelets in registax6
  5. After months of missed opportunities, I finally managed to spot (and capture) the elusive Mercury! I was observing from the middle of a city, and due to high level of air pollution anything bellow 10 degrees near the horizon is very, very tough to see. finding Venus itself took me 10 minutes with binoculars, It was right among some clouds. mercury should have been to the bottom right of it but it wasn't visible. I took some photos of venus and just as I was about to give up on mercury and go inside, I looked one more time and there it was, so faint it was barely noticeable. I was elated and managed to get some shots of it, finally completing my solar system planets bucket list these have been taken over 4 years from 2014-18. the sun, earth (:p) and mercury shots are using a canon 600d, and all others are with the canon 600d + nextar 8SE.
  6. 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=]
  7. Horizon at 8 pm, BBC2 "The end of the Solar System" We're alllll dooomed, dooomed I tell ye!
  8. Decided to brave the warm weather in the San Francisco Bay Area to grab a photo of AR1504 and its friends. I was going to grab video using the Canon 1D MarkIII and the 3x Barlow but the laptop got too hot and turned off. So I decided to take several photos praying I would get a clear picture out of the set.

  10. The definition of a moon is a natural object (or satellite) that orbits a planet. To my understanding Saturn's rings are made up of space debris, and they must orbit around the planet. Does that mean that each individual piece of debris and dust in Saturn's rings, and other planet's rings, count as moons?
  11. Here's The big man from a couple of nights ago, I'm desperate ti get a bit more info out of it but I've started with AS2 and it's pretty good software. Would love to have a go with a 4x or 5x Powermate but could do with some motor driven focusing. Thanks for looking, other stuff is on my flickr site.
