  1. 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?

  2. 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!

  3. 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!

  4. 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.
  5. 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!
  6. 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
  7. 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!

  9. 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...........
  10. 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!

  11. 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.
  12. 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!

  13. Hi all, I was lucky to have the opportunity - and the sky - to watch and sketch the transit. This sketch has been done at the beginning of the transit, showing Mercury at about 1320 CEST near the prominence at the eastern limb. Telescope: Lunt LS50 THaB600PT Eyepiece: TS HR Planetary 7mm Date & Time: Mercury transit time Location: Dusseldorf region, Germany Technique: Koh-i-Noor soft pastels and pastel pens on Daler Rowney Ebony black sketching paper Clear and sunny skies! Achim
  14. Heres a pic from the other night with fairly heavy moon glow of IC1805, Showing inner detail. 29 x 6 min subs. Taken through the MN190, and an Atik 314 mono.
  15. Hello everyone, I decided to take the big step and send my tilt tuned Lunt LS60 to Arizona for a pressure tune retrofit, cost $500 US but after reading countless opinions from pressure tune users I decided it would be worth the dough. Cant wait to get it back now, turnaround time is about 30 days or less they tell me, oh man I wanna see now, god I hate waiting for things!.
  16. Hi all, today I sketched the wonderful sunspot AR2529 in both H alpha and in "white" light. In fact, in order to have a quick comparison of the two spectral ranges without swapping scope and eyepiece, I simply detuned the pressure tuner of the Lunt completely. It worked sufficiently well: When being fully detuned, the Lunt just shows a red sun with sunspots as if they would have appeared on a white sun with normal telescope and solar filter. Here's my sketch: Telescope: Lunt LS50THaB600PT Eyepiece: Skywatcher Planetary 5mm Date & Time: April 15th, 2016 / 1730-1815 CEST Location: Home terrace, Dusseldorf region, Germany Technique: orange and white pastels and pastel pens, charcoal pen on black sketching paper. Hope you enjoy it! Achim
  17. Wow what a beautiful prominence visible just an hour ago, if you have an H Alpha scope get it out there!
  18. Hi all, after weeks of "astronomical absence", I set up the Lunt LS50 on the terrace this afternoon and did a small pastel sketch of the wonderful prominence at the northeastern limb. Telescope: Lunt LS50 THaB600PT Eyepiece: Skywatcher UWA 5mm/58° Date & Time: July 3rd, 2016 / 1440-1510 CEST Location: Home terrace, Dusseldorf region, Germany Technique: orange pastel pens on black sketching paper I hope you enjoy it Clear skies!

  19. Cocoon nebula taken from last year, and last night combined and stacked. 30 x 6 mins exposures, but there was a few 8 mins in there as well. taken through the MN190, ATIK 314L plus mono, and 7nm h-alpha filter. When I get the chance I will add colour.
  20. Hi all, today I could just have some quick glances at our home star trough small gaps in the clouds. There was a nice prominence which was already lifted off from the solar "surface". So I gave it a try with a quick pastel sketch. Unfortunately the clouds won and I had to do the sketch in a bit of a hurry. Anyway, I'll sharing it here with you... Telescope: Lunt LS50 THa B600 PT Eyepiece: TS HR Planetary 5mm Date & TIme: March 6th, 2016 / 1200-1215 CET Location: home terrace, Dusseldorf region, Germany Technique: orange pastel pen (Koh-i-Noor Gioconda) on black sketching paper Hope you like it! Achim
  21. 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! Achim
  22. Hi all, today I set up the Lunt 50 on the terrace to have a quick look at our star. At first I was a bit disappointed since there were no large prominences visible. At a second glance and with some fine tuning of the Etalon, I recognized that the solar surface was looking fine too: The two sun spots AR2524 (the left one in the sketch), AR2526 (the right one), some filaments - and at the edge even a small protuberance were visible. I took a pencil sketch of the whole disc in my observation logbook. Here's a scan of it: Telescope: Lunt LS50THaB600PT Eyepieces: Skywatcher Planetary 5mm, Celestron X-cel 10mm Date & Time: March 26th, 2016 / 1200-1230 CET Location: Home terrace, Dusseldorf region, Germany Technique: 2H, HB and 2B pencils on white sketching paper Clear - and sunny - skies!
