  1. Hi guys, I wanted to share with you a detail of an AR I captured with my modest setup some days ago. Nothing fancy or special, but it is the first time I have managed to get such level of detail, so I'm happy with it. Setup SW 114/900 Newton on EQ2, motor focusing Prestigio PWC2 webcam, IR-cut filter, Baader Astrosolar, Hyperion Zoom Barlow 2.25x Enjoy.
  2. After months of wait in July we finally could see the big sunspot Noaa 1785, and now that it has finished its passage over the Sun disc I propose you a summary of its evolution in the central week. I always find it amazing how quickly evolve and migrate structures of planetary dimensions. If you check the animations of the last year suspots on my channel, you can see that we are still far from the huge ones of 2012 but hope you like it. I suggest to watch at full resolution, the tube compression is heavy and only at max res you can enjoy better the details
  3. Sunspot groups AR1787, AR1785 & AR1784 are prominent in this image of the rising Sun behind the James Thomson monument near Kelso & Ednam. James Thomson was a poet & dramatist born in the village of Ednam in 1700 and perhaps best know for writing the words of 'Rule Britannia'. Pentax K5 Pentax 800mm lens @ f45 Exp. 0.5 sec.

  4. I think I have done well may be able get some more out with pro settings on my phone I will have to experiment.
  5. Today during my solar observation session I spoted two groups of white sunspots close to the solar limb. This is the first I see them. They are located between sunspot 1519 and solar limb, and between sunspot 1522 and solar limb. I checked the SOHO site, and found a HMI picture that confirms the white spots. http://sohowww.nasco...nspots_1024.jpg I am using a 102 nexstar with a Baader film. Because I only noticed them today I checked the SOHO database to see if they were there since when I saw the AR1520 for the first time. But they were not there, at least not visible in the SOHO pictures as well. For the most experienced solar observers, is it correct to afirm that these white spots are only visible when closer to the limb? If this is true, how does it happen? It is quite interesting that the white spots came to my attention due to some clouds passing in front of the sun. I put a moon filter to get a bit more of contrast. There was a small improvement in the contrast, but nothing like a clear view like the normal black sunspots. Does anyone can give me a tip to get a bit more of contrast on those white sunspots? Baader continuum filter? It will be nice to hear your experience observing those. This is my first week observing the sun! Thank you
  6. AR 1520 is my first sunspot, seeing through a telescope with a solar filter that I did it myself, I am so amazed with the these sunspots. When I used my BGO 12.5 I was able to see some granulation around the sunspot. Very nice sunspot with umbra and penumbra delicate lines inside the two main black spots. Really nice. I took the opportunity and made a shoot with my mobile.
  7. Captured this afternoon in Mandurah, Western Australia. Taken with the ZWO ASI224MC and the Celestron 8i SCT with focal extension tubes and white light solar film filter. A two minute video was captured with the final image being cropped and having 10%, 112 frames aligned and stacked in Autostakkert 3, wavelets in Registax 6, edited in PaintDotNet.
  8. Got a quick few shots of the rather psychedelic looking sunspot on show today, so enhanced the best one from my iPhone 7+ which came out pretty well methinks. Not a patch on other members offerings I know, but shows what can be done with a phone camera still.
  9. Just been having a look at Sunspot AR2715 this afternoon ... equipment is ED80 , Baader filter and ES 8.8/82 ... I usually observe from indoors through a skylight double glazed window with a smaller 400mm ST80 , so wanted to try the longer reach of the ED80 600mm and see if being outdoors might give better results - in short , it did ... a lot more clearer dots giving a distinctive V formation resembling the Wild Duck cluster . PS , had to borrow my nieces teddy to stand in as a “ stunt double “ as I was taking the pics ...
  10. Hi all, this noon, I observed the sun with the Lunt 50, in particular the great sun spot AR2529 which looked wonderful in H-alpha. During the observation, two bright spots close to each other appeard (one at the southern edge of the sun spot, the other one a bit more to the south east). I really enjoyed to see the solar surface gradually change while I was observing. Here's my sketch: Telescope: Lunt 50 THa B600 PT Eyepiece: Skywatcher Planetary 5mm Date & Time: April 9th, 2016 / 1130-1230 CEST Location: balcony, Dusseldorf region, Germany Technique: Koh-i-Noor pastel and charcoal pens on Daler Rowney Ebony black sketching paper Clear and sunny skies!
