  1. Wow!! that is incredible! how did you know about the broadcast? what else do you download Alexandra
  2. I just buy mine (easier) https://www.firstlightoptics.com/other-science-gadgets-models-toys/solarcan-ready-to-use-solargraphy-camera.html Alexandra
  3. First, well done on the Solarcan, it is always so exciting to break it open and see the paper with lines on. Second, don't angle the next one keep it straight. This is a camera obscura https://en.wikipedia.org/wiki/Camera_obscura Therefore, the image is produced upside down. So to raise the height of your solar tracks you need to maintain the can in a straight position but you must move the pin hole upwards. I tried this this year and managed to get more tracks but still not high enough. I made my hole exactly half way between the middle and the top. I tried to get it higher but
  4. Hi Richard, if you click on the link above you will see what I bought https://www.firstlightoptics.com/other-science-gadgets-models-toys/solarcan-ready-to-use-solargraphy-camera.html all the information is at the bottom of the page. It is Ilford's photographic paper Alexandra
  5. My Solarcan finished on the 21st December and on Christmas day I cut it open. It was a little wet inside with 1ml of water but I think that was from all the storms we had in summer. I had to let the paper dry in a drawer for half an hour and then it scanned in OK. I am much happier with the position of the pin hole this year. Last year I used the standard in the middle, this year I added one half way between middle and the top (3/4 upwards) and this worked a lot better. I still think I could raise the hole higher. https://www.firstlightoptics.com/other-science-gadgets-models-toys/sol
  6. By the way, you only need to expose for 6 months, everything else thereafter is just overwriting previous exposures tracks. There is nothing to be gained for leaving it for 8 and half years, unless of course you live in the most cloudy part of the world in existence Alexandra
  7. I buy all mine from FLO Luke My next one is due off on Christmas eve. Like the above image all the summer trails are knocked off, so this year I experimented by not using the hole that comes with the can and I have placed another half way up the can to see if I get more of the summer trails. We shall see....... This was last years attempt which I was pleased with but disappointed with at the same time. I would be disappointed after 2 and half years too! 2019-12-24 Solarcan by Alexandra Hart, on Flickr The can from FLO Alexandra
  8. Luke, the reason for not seeing the proms in the single stack and seeing them in the double stack is because the dynamic range changes. The eyeball in single stack can see the proms more easily but the dynamic range is large and therefore bad for the camera. In double stack the whole image is darker but more even and therefore the dynamic range is closer together so the camera can see the surface and the proms together. The Chameleon is excellent for the PST (better pixel size for resolution) but the Newton's rings are horrible! I'm getting there with the help of software for pattern sup
  9. I have a recent comparison but I was still getting used to the PGR Chameleon and the Sun wasn't that brilliant either so the images are a bit dull. This is with the PST.

  10. Oh that is the best transit I have ever seen!!! are they Sandhill Cranes? Alexandra
  11. These are just brilliant! Alexandra
  12. You always get the most beautiful and stunning Calcium K images and animations Alexandra
  13. Thanks guys x6gas, yes 3 wins (2014, 2017 and 2020) but never the main title, there is always a challenge I can hope.... I still have a long way to go to match the amazing work of others like Christian Viladrich, Alex, Valery, JP etc but that is what keeps you fighting. However, most of the time it is more satisfying and fun to just stop, sit and enjoy the Sun with your eyeballs and sketching pad, and most of all, showing others. Alexandra
  14. Thanks guys for the lovely wishes, it does mean a lot I am always looking at your images even if I don't comment all the time. I love to see what everyone is doing.
