  1. I heard the sun wasn't very active at the moment. Is it still active when you look through H-Alpha? (I don't really understand the difference!)
  2. Dear all, now the summer heat seems to be gone. It's still sunny but not that hot anymore. Perfect weather for sketching for the H alpha sun: Telescope: Lunt LS50THaB600PT Eyepiece: Celestron X-Cel 10mm Date & Time: August 30th, 2019 / 1230-1300 CEST Location: home terrace, Dusseldorf region, Germany Technique: reddish Koh-i-Noor Toison d'Or pastels and pastel pens on yellowish Canson Mi-Teintes pastel paper Clear and sunny skies! Achim
  3. Dear all, today morning I had a look at the GONG network images on the internet and set up my telescope to have a look at that awesome large prominence on the southeastern limb of our home star. First I concentrated on a sketch of just that wonderful prominence. After that, I created - as usual - a sketch of the full solar disc. I noticed that the prominence already had changed during my sketching time. Telescope: Lunt LS 50 THa B600 PT Eyepiece: TS HR Planetary 7mm Date & Time: June 28th, 2019 / 1045-1145 CEST Location: home terrace, Dusseldorf region, Germany Technique: natural vine charcoal on white Hahnemühle Ingres mould-made pastel paper Size: 24x31cm  Clear (and sunny) skies! Achim
  4. Dear all, today once again, I did a charcoal sketch of our star bringing us 33°C before lunch time. The solar "north pole" is approximately at the prominence at the top of the sketch. The sketch is right-left flipped. Beside the orientation of the north pole, I figured out on the internet that the bright spot in the left area of the sketch is AR12745. The disc and parts of the prominences is done with natural charcoal. The filament and the dark areas of the prominences are done with the charcoal pen. Telescope: Lunt LS 50 THa B600 PT Eyepiece: Celestron X-cel 10mm Date & Time: July 23rd, 2019 / 1130-1200 CEST Location: home terrace, Dusseldorf region, Germany Technique: natural vine charcoal and Koh-i-Nor charcoal pen on white Hahnemühle Ingres mould-made pastel paper Size: 24x31cm Clear (and sunny) skies! Achim
  5. Dear all, as usual, I couldn't resist to create yet another charcoal sketch of the H alpha sun. It is relaxing for me to observe the proms and filaments and to try to catch them "as they are" on the paper. At first glance, the sun looks pretty similar - just at second glance and comparison with my other sketches, I have seen that it looks similar but always a bit different. The disc and the prominences are done with natural charcoal, just for the filaments, I needed a Koh-i-Noor artificial charcoal pen since it's darker. Telescope: Lunt LS 50 THa B600 PT Eyepiece: Celestron X-cel 10mm Date & Time: July 1st, 2019 / 1015-1045 CEST Location: home terrace, Dusseldorf region, Germany Technique: natural vine charcoal and Koh-i-Nor charcoal pen on white Hahnemühle Ingres mould-made pastel paper Size: 24x31cm Clear (and sunny) skies! Achim
  6. Dear all, these days we have a sunny and hot summer over here. Today I tried to capture the "aura" of the sun caused by some dust in our atmosphere when doing the pastel sketch of the H alpha solar disc. I spent almost half an hour with the solar disc and its aura and then just 15 minutes for the proms and filaments. So here's the result: Telescope: Lunt LS50THaB600PT Eyepiece: Celestron X-cel 10mm Date & Time: June 26th, 2019 /1030-1115 CEST Location: home terrace, Dusseldorf region, Germany Technique: red and orange Koh-i-Noor pastels and pastel pens on black Canson Mi-Teintes pastel paper Size: 24 x 32 cm Clear (and sunny) skies! Achim
  7. Dear all, today at 30°C, I had a look to the H alpha sun the first time in summer this year. Here's the natural charcoal sketch of it: Telescope: Lunt LS 50 THa B600 PT Eyepiece: Celestron X-cel 10mm Date & Time: June 23rd, 2019 / 1200-1230 CEST Location: home terrace, Dusseldorf region, Germany Technique: natural vine charcoal on white Hahnemühle Ingres mould-made pastel paper Size: 24x31cm  Enjoy the summer with clear (and sunny) skies! Achim
  8. Dear all, today I had a look at the GONG H alpha network monitor (http://halpha.nso.edu/) and figured out that the filaments of the past week have now reached the solar limb and at least the final one of it appeared as wonderful set of prominences. On my left/right-mirrored sketch this is the one in the lower left sector - if I consider the 5 hours difference of daytime compared with the previous sketches correctly. So, here's the sketch: Telescope: Lunt LS 50 THa B600 PT Eyepiece: Celestron X-cel 10mm Date & Time: June 14th, 2019 / 1500-1530 CEST Location: home terrace, Dusseldorf region, Germany Technique: natural vine charcoal on white Hahnemühle Ingres mould-made pastel paper Size: 24x31cm Clear (and sunny) skies! Achim
  9. Dear all, two days after the previous sketch, I made another pastel sketch of the H alpha sun showing quite well, how the sun rotated and how the filaments and prominences have changed in two days: Telescope: Lunt LS 50 THa B600 PT Eyepiece: Celestron X-cel 10mm Date & Time: June 7th, 2019 / 1000-1030 CEST Location: home terrace, Dusseldorf region, Germany Technique: reddish and black Koh-i-Noor soft pastels and pastel pens on light-grey Hahnemühle Ingres mould-made pastel paper Size: 24x31cm Here's the direct comparison: I struggled a bit with the white balance on the smart phone camera when taking the pictures of the sketches. Both are done on the same light-grey paper. Clear and sunny skies! Achim
  10. Dear all, the prominences of the previous days on limb of the sun now are visible as filaments on the solar disc itself. Lacking amazing prominences on the limb, I hsve been concentrating on sketching the filaments this time. Compared with my previous sketches they moved from the right towards the middle. Note that my sketches are usually left-right-flipped due to the telescope's mirror. So here's the result: Telescope: Lunt LS 50 THa B600 PT Eyepiece: Celestron X-cel 10mm Date & Time: June 7th, 2019 / 1000-1030 CEST Location: home terrace, Dusseldorf region, Germany Technique: reddish and black Koh-i-Noor soft pastels and pastel pens on light-grey Hahnemühle Ingres mould-made pastel paper Size: 24x31cm Clear and sunny skies! Achim
  11. Dear all, this morning, I woke up because of lightning and thunder here in Dusseldorf area. After the thunderstorm had moved away towards northeast- and before the next bunch of clouds appeared, I enjoyed the sunshine on the home terrace. To maximize my joy, I set up the H-alpha-telescope to have a look at the solar "weather". This time I once again chose natural vine charcoal which is made of the very same atoms than the solar nucleus: carbon. The prominence on the top limb of my sketch was pretty tricky to sketch its set of needle-sharp "rays" in front of the foggy background. Telescope: Lunt LS 50 THa B600 PT Eyepiece: Celestron X-cel 10mm Date & Time: June 3rd, 2019 / 1000-1030 CEST Location: home terrace, Dusseldorf region, Germany Technique: natural vine charcoal on white Hahnemühle Ingres mould-made pastel paper Size: 24x31cm Clear (and sunny) skies! Achim
  12. Dear all, today we had a wonderful sunny day over here in Germany and I took the opportunity to do a pastel sketch of our home star. As usual, the image is mirror-reversed. Telescope: Lunt LS50THaB600PT Eyepiece: Celestron X-Cel 10mm Date & Time: May 29th, 2019 / 1630-1700 CEST Location: home terrace, Dusseldorf region, Germany Technique: reddish Koh-i-Noor Toison d'Or pastels and pastel pens on greyish Canson Mi-Teintes pastel paper Size: 24 x 32 cm Clear and sunny skies! Achim
  13. Hi all, now finally after waiting for ages (at least it feels like this ), I had a another look at our home star through my new Lunt 50mm H-alpha telescope. We've been visiting my in-laws yesterday and this time I did my first sketch with reddish pastels. I'm not fully happy with the result: I used pastels and pastel pencils in different reddish colours (yellow, orange, dark orange, etc.) but it seems that they are not exactly just different brightness of the same color tone. Instead they appear to be really different colors.So I'm still trying with those to improve my results. As an alternative attempt maybe I'll go for just doing a sketch with chalk and charcoal like I do with my lunar sketches and put the color on it later at the computer. What I'm fully happy with is that I could show the sun in H alpha light to my family yesterday. They were indeed impressed. Telescope: Lunt LS50THa B600 PT Eyepiece: Celestron X-cel 10mm Date & Time: February 6th, 2016 / 1500-1530 CET Location: balcony, Dortmund area, Germany Technique: orange and red pastels and pastel pens on black sketching cardbox Hope you like it! Achim
  14. Gents, I'm looking for a new Halpha set up, and am looking for suggestions. I've got a budget of ~£2000 (might be able to stretch a bit). Like to image proms with decent detail with fair bit of surface features (Quark takes care of the surface detail). I'm leaning towards Lunt but not sure to go for LS50 or LS60, would welcome suggestions from Lunt users (not sure solarMax will be in budget). I hoping to be able to reuse my Celstron 6SE Goto (been using this with SW ED80 and Quark) and ASI174MM. Any suggestions welcome. Thanks in advance.
  15. Hi all, this afternoon the sun was shining so nice and bright that I picked the Lunt and put it quickly on the pipe mount. There were two wonderful, very detailed prominences. I picked the finer one and did a quick pastel sketch of it. Here you are: Telescope: Lunt 50 THa PT B600 Eyepiece: TS HR Planetary 7mm Date/Time: March 12th, 2016 / 1520-1545 CET Location: Home terrace, Dusseldorf region, Germany Technique: reddish pastel pen and pastel on black sketching cardbox Hope you like it! Achim
  16. Hi all, today, in white light, the sun was totally blank. I didn't see a single sun spot. So I didn't sketch it .However, in H alpha with the Lunt 50 there were some nice proms. This is the pencil sketch in my observation notebook: Telescope: Lunt LS50THaB600PT Eyepiece: Celestron X-cel 10mm Date & TIme: 2016-06-05, 1215-1245 CEST Location: Home terrace, Dusseldorf region, Germany Technique: 2H and HB pencils Clear skies! Achim
  17. Dear all, this weekend turned out to be a wonderful solar sketching weekend for me. Today I had another great chance to do a pastel sketch - and in fact the selected prominence was even larger and more structured than the one yesterday. So here we go: Telescope: Lunt 50 THa PT B600 Eyepiece: TS HR Planetary 7mm Date/Time: March 13th, 2016 / 1520-1550 CET Location: Home terrace, Dusseldorf region, Germany Technique: reddish pastel pen and pastel on black sketching cardbox Clear skies and a good start into the coming week for all of you! Achim
  18. Hi there, Apologies if this has been posted before but I have been wondering why narrow band (>1nm bandpass) give so much solar detail. Is it because the magnetic field of the Sun shifts H alpha emission towards/away from the filter bandpass - giving contrast in a filtered image? Or is there something else going on. Many thanks!
  19. Heres my version of the flame nebula, take last month. Taken through my MN190, in h-alpha, the camera was an Atik 314 mono. Did this one last year, but more subs this time improved it from last attempt. 18 x 8 min subs...........
  20. Hi all, as written in Douglas Adams' Hitchhiker's Guide to the Galaxy, we're moving around a small unregarded yellow sun. In fact today at first glance there was really nothing extraordinary visible on our home star: It was fully blank in white light and even in H alpha there was no spectacular eye-catcher. Nevertheless I did a pastel sketch - I had prepared the solar disc already before anyway . So here we go: Telescope: Lunt LS50THaB600PT Eyepiece: Celestron X-cel 10mm Date & Time: March 16th, 2017 / 1100-1145 CET Location: Home terrace, Dusseldorf region, Germany Technique: reddish pastels and pastel pens on black sketching paper Diameter: 8" Clear skies! Achim
  21. Hi all, the day before, I spent some time after work on the terrace and had a look at our star - through some cirrus clouds. This time, I did again a pencil sketch of the whole solar disc, even though it looked a bit "boring" now that AR2529 has vanished. Telescope: Lunt LS50THaB600PT Eyepiece: TS HR Planetary 7mm Date & Time: April 21st, 2016 / 1730-1800 CEST Location: Home terrace, Dusseldorf region, Germany Technique: 2H, HB and 2B pencils on white sketching paper Hope you enjoy it! Achim
  22. Heres an image from a few nights ago (8th) of a section of the Veil nebula. exposures were not as long as I would have liked due to cloud passing over, conditions were very average. This is a bi-colour image taken through the skywatcher mak Newtonian scope, an Atik 314L plus mono, with a 7 nm h-alpha filter, and an OIII filter. the h-alpha filter was 10 x 5 mins exposures, and the OIII filter was 9 x 5 mins.

  24. Wow what a beautiful prominence visible just an hour ago, if you have an H Alpha scope get it out there!
  25. Hi, I currently have a Lunt 50THa and I am looking for something showing more detail and contrast on the sun's surface. I have been considering the new Meade SolarMax III 70 Double Stack, the Lunt 60 with DS (fairly expensive in comparison) and now stumbled across the Daystar Chromosphere. My key considerations: - I love that I can just take out the Lunt at lunch time, put it on a photographic tripod, and I am up and running in about 5min. - When travelling, it would be easier to have one telescope to take with me for day and night use - Cost is certainly an aspect - I do not want to spend more than about 3000 pounds. May I get your input on a couple of assumptions I am making (and which may be completely wrong - sorry, I am not a telescope expert, I just love using them...) - The only purpose of double stacking is to get a narrower bandwidth using (cheaper) filters with a wider bandwidth - by using two 0.7nm filters tuned to slightly different bandwidth the Lunt and the Coronado achieve 0.5nm effective transmission. - A Daystar Chromosphere with a transmission of <= 0.5nm will hence show me the same detail as a Lunt or Coronado Double Stack with a single Etalon - A refractor up to 80mm does not require an additional ERF - A relatively cheap achromat will do - as I am only observing at a single wavelength, the correction for multiple wavelengths really does not make a difference (at least for H alpha) So on that background I guess an 80mm refractor with the DayStar will give me a really good solution am I right? Best Thomas
