  1. Hi, On TheWeatherOutlook web site I've recently added cloud forecast charts from the Meteo France Arpege computer model which should (hopefully!) be useful for astronomers. Arpege is a higher resolution computer model than the Global Forecast System (GFS) which is also available on TWO and other web sites, in addition it is stepped at 1 hour rather than 3 hour intervals. You can view the cloud forecast charts from the link below: http://www.theweatheroutlook.com/twodata/arpege.aspx?charttype=cloud&model=arpege&region=uk&charthour=1 PS: TheWeatherOutlook is available as a free IOS and Android app from the Apple App and Google Play stores respectively. The current version of the app includes cloud forecast charts from the GFS but not Arpege. The next release should be bundled with Arpege too.
  2. Thanks for the suggestions. Not sure whether I want to spend the extra money on a lithium ion battery. Would something like this be a decent replacement: http://www.maplin.co.uk/p/5-in-1-power-station-with-air-compressor-a67hy
  3. The title is self explanatory I hope! My second Skywatcher power tank which is about 18 months old has packed up despite not being overused or allowed to run flat. I wouldn't mind paying over the odds for the Power Tank if it was a reliable product, but frankly to see the second one go so quickly is ridiculous. I've decided it won't be third time lucky with the Power Tank and would like to replace it with a suitable portable power supply of the type that Maplins or Amazon sell. Can anyone recommend one?
  4. I'm the owner of TheWeatherOutlook (TWO) site and a keen amateur astronomer. The Norwegian site mentioned above is a good one to use because I think it uses data from the European ECM model. On TWO there are a number of resources in addition to the local forecasts to help. The most useful probably are: Astronomy forecast page - available by expanding the +/- menu options near the top of the page. Enter your location in the place or postcode then press Astro: http://www.theweatheroutlook.com/twoforecasts/forspecialist.aspx?postcode=London Detailed forecast page - enter your location then select the day and click on the 'Detailed weather forecast' link near the bottom of the page. This shows forecast cloud cover at low, medium and high levels. If you'd like to dig a little deeper go to the Chart viewer page here: http://www.theweatheroutlook.com/twodata/datmdlout.aspx UK cloud cover forecasts are available from the GFS model and the HIRLAM model.
  5. Thanks - that seems to have fixed mine too.
  6. I'm going to try connecting it to my car battery today using the starter cables and then leave my car engine running a whiler. Hopefully this should put some charge back in the power tank.
  7. Thanks for the suggestion but this didn't work.
  8. I've not used my Skywatcher power tank for a while so thought decided to charge it up. I've plugged it in, and set the switch to 'Charge' but the lights on the power tank are not illuminating. I've tried the radio and torch, but they don't switch on either - it's possible the power tank is completely flat. The power socket and charger are working, so the problem must be with the power tank. Any electrical experts here got suggestions on where I should start looking?
  9. On TWO there's also the IR satellite overlay which is quite useful at times: http://www.theweatheroutlook.com/twodata/uk-ir-satellite-image.aspx (The web site is mine, but I'm also a keen amateur astronomer)
  10. You can also get the raw cloud cover charts on TWO here: http://www.theweatheroutlook.com/twodata/datmdlout.aspx If you're lucky (or unlucky depending on your POV) you may get some snow in the next couple of weeks.
  11. Thanks - that's an expensive solution! I'll speak to FLO and see whether they can help, although my scope is out of warranty. Generally the build quality of the Skywatcher is good, so it's annoying when something minor like this goes.
  12. I've also go the same problem with the rubber feet on my EQ5 tripod splitting. My scope was bought from 1st Light Optics, so I'll contact them and see how things go! As an aside, do you know whether it's possible to get better rubber feet (than the ones shipped with it as standard) to reduce vibration?
  13. I'm the owner of TWO and post on here at times as I'm a keen amateur astronomer too. I've recently added a couple of new features to the site which compliment the cloud cover forecasts quite well, and could be useful here. These are the IR satellite cloud image overlay and the rainfall radar, links below. Both pages update every 15 mins. http://www.theweatheroutlook.com/twodata/uk-ir-satellite-image.aspx http://www.theweatheroutlook.com/twodata/uk-rainfall-radar.aspx PS: Mods/admins, hope it's ok to post links to my site but if not then obviously delete and I'll understand!
  14. Hi. I'm the TWO site owner, and a member here because I'm also a keen amateur astronomer. As a result I don't like to spam my site on here, but if you or anyone else has questions about the weather/TheWeatherOutlook site please feel free to ask. In general terms the outlook is pretty mediocre for astronomy, although at this time of the year I rarely bother setting up my scope regardless of the weather because the nights are so short.
  15. Much better tonight. I was able to see surface detail clearly, and possibly (but not sure) even the (north??) ice cap. Quite pleased.
