  1. Thanks for the tip Alexandra. Short nosepiece solved the problem. First processed image of full disc (ignore the dirty 'blob'), but time was pressing and I didn't have time to clean any surfaces within the light path. The sun was very low and luckily I managed to snatch this shot as the sun moved between neighbouring trees and a house. My main aim was just to try out the new nosepiece. Regards Stu.

  2. Thanks Alexandra. I'll give it a go and see if this works in my case. Knowing my luck....... We'll see. Also meant to say, great images, as usual. Thanks for the tip. Regards Stu.
  3. Hi Alexandra, You've probably explained this before in other posts, but your Ha full disk shots are taken using a PST with DMK41. So how do you get the PST to focus and how do you reduce the size of the solar image to fit onto the DMK41 chip? I assume you are using a focal reducer, but mine just won't work at all. I can't achieve focus and can only do so with a barlow, which, of course, takes things the wrong way by magnifying rather than reducing the image size. Sorry for such a basic question, but this is a frustration!! My 150mm Ha solarscope is fine for 'close up views' but I cannot get a good full disk image in one shot! Thanks Stu.
  4. Stunning images Alexandra. SF-100/DMK 41 combo really works well. Were the prom images taken using high gamma and then processed to pull back some contrast, as you have done before? I tried this and got 'washed out' images. Regards Stu.
  5. Good luck with that Episkey. Looking forward to seeing your results. Stu.
  6. Excellent shots there Ian. Great capture of the lift-off prom! Stu.
  7. The sun is putting on a fine display. Nice proms and AR1476 is still a great target for the garden solarscope! Stu.
  8. Some really nice proms today! These are huge! 150mm F10 with PST etalon. Stu. Capture 12_05_2012 13_47_17.tif
  9. Many thanks Ken/Alexandra. Much appreciated. Stu
  10. I lugged my EQ6 and telescope in and out of the house three times today dodging showers and waiting for some sunny spells, but it was worth it, as I finally managed to capture a few AVI's of sunspot group AR1476 at hi-res. This is quite some active region!! Thanks for looking. Stu.
  11. Thanks Ken, This was taken using a 150mm refractor with an internal 90mm ERF fitted with PST etalon and BF15. I used a 2.5X Televue Barlow to get to f25 and a DMK41 to capture the image in monochrome. Achieving a good image with this set-up can be a bit tricky, but I've found that rotating the BF and using a polarising filter on the camera seems to reduce any artefacts. No sun to send unfortunately, but will do when it shows again!
  12. Many thanks everyone for your comments. I just wish we had more sun today; still it IS a Bank Holiday!! Stu.
  13. Managed to capture a few AVI's yesterday before the clouds rolled in here in NW. Tricky to get anything really suitable, but here's AR1471 in hydrogen alpha. Processed with AviStack2, PixInsight,Gimp,Photomatix,Picasa3........so a lot of image processing!! I hope you like it. Cheers Stu.
  14. Superb images Alexandra!! Wonderful fine detail and expertly processed. Stu.
  15. Thanks Alexandra. I think the P-HDR effect on a full disc is more subtle than it is when using magnified views and the result may not be to everyone's taste. Some prefer a flatter image with uniform illumination. I prefer one with a bit of limb darkening, as in my opinion this enhances the fact that the sun is a spherical object, although I think similar 'illumination' effects can be achieved without using P-HDR. Need more sun here too.....
  16. More experimentation with P-HDR solar. Not as dramatic as it is with close-ups, but let me know what you think. Thanks to MarkT for allowing me to use one of his full disc images (from April 12th) as the basis for this demo. Cheers. Stu
  17. Very nice image there Steve. Stu.
  18. Wonderful images there Alexandra! Stu.
  19. OMG Alexandra.....stunning. Superb detail. Stu.
  20. Excellent Mark. Beautiful detail! Stu.
  21. No problem. I hope you find it useful. It can be a bit fiddly to get right, but the results can be worth the effort. Regards Stu.
  22. Hi Alexandra, Sorry, I simply meant that it is not as simple as just selecting 'HDR mode'. As you know, there is more to it than that. I've just checked out your image and it looks like it is coming along great. I find that I have to make a number of adjustments to get the right blend between the different images to bring out the best results and result do vary, as they say. Regards Stuart
