  1. 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
  2. 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. Moderating Solarchat these days seems to take a lot of time up Insight Astronomy Photographer of the Year 2020- Our Sun - Winner by Alexandra Hart, on Flickr Alexandra
  3. Wow!! star quality work! well done Alexandra
  4. Absolutely stunning work!! I am loving your CaK results Alexandra
  5. Cracking animation! is that a transitory pore opening up and disappearing? what was the timescale? Alexandra
  6. That's fabulous! not many people do CaK animations and it does produce this strange surface effect, nice work Alexandra
  7. Absolutely fabulous images! thanks for sharing Alexandra
  8. I have also found that I can't remove the dust bunnies from my ASI174 and flats don't work that well either. However I dropped my camera the other week on the floor with much cursing but the bunny shifted and is gone! hooray! however I don't recommend dropping your camera deliberately. The dust is on the inside and can't be blown away and I find it the most irritating camera I have ever owned. A friend had success by using an anti static gun for use on records (do you remember them) and it helped it to unstick off the window. Alexandra
  9. Tej, I had exactly the same problem. don't use oil. Use the rubber boa, I had never heard of one either but found one in a local hardware store. It comes with full instructions on the packet I had tonnes of loctite on mine and sadly had to enlist the help of the hubby as I was not strong enough to do it. What I found a huge help was using a hairdryer. Let it blow on the area (not too close - like you would to your hair) for 5 minutes. When it was nice a hot the hubby went for it and it just shifted straight away. Alexandra
  10. I think Michael says it all. Flats are very hard to get right. I think taking a flat near the centre is OK in most circumstances, but when you have such a close up with huge lights and darks it will compensate in the opposite direction. I once chatted with Emil about this and he seemed to indicate that it would never work well. Also, do you have two images here and doing a composite? if so, you don't need to use a flat on the over exposed image as dust bunnies never show on the black of space anyway, then use the flat on the disc part only as you aren't using the black space area for that picture anyway, so it should be win win all around. It is called the art of fudging, getting round the problem to get a great image Why are you still using ASK2? ASK3 has been around for ages is is much better These are terrific images by the way, superb resolution and it looks like you got round the dust bunny situation anyway Alexandra
  11. Wow!! maybe the Basler and FLIR versions have better cooling systems for the chip! I need to check my temperature of my ASI174 next time I am out, maybe it needs a cooler attached? it probably has Covid-19 Alexandra
  12. Yep, your prominence is full of little dots. All my images are full of little dots and it puts me off using it. I have to use very aggressive de-noise on all my images to get rid of them. I thought I was just being useless and maybe not stacking enough, but I have never seen others having this problem you see. I regret not spending the extra couple of hundred for the Grasshopper or Basler version Now I see your prom image, it does look like mine. However I don't see a weird condensation look when in live view like you showed before. All my grain comes when I try to post sharpen the stack. I have tried no gain vs some gain and it is still just as bad. Even stacking more and the dots are still there but the detail of the image are lost. With my Grasshopper (different chip) I can stack as low as 20-50 images and still not have dots, for the ASI174 I have to stack more than 300 to be even reasonable which is not an option for hires work. Good luck! Alexandra
  13. I wish I could see this more clearly what you are talking about here. I also get a very annoying grain in all my solar images with the ASI174 which the Basler and Grasshopper versions don't seem to suffer from. I have to use very heavy denoise to get rid of it but sometimes I think, is this solar structure or noise as it is so consistent. I'd love to see close up exactly what you mean to compare to mine. Alexandra
  14. Beautiful!!! but surely it should capture video with the Basler software, it is a video camera? Alexandra
  15. A great start first images are always such a major triumph, so well done! The first thing you need to do is bring the exposure right down, a lot. You will then find that focus is much easier. Practice will make perfect so keep up the good work! Alexandra
