Pastel sketch of the H alpha sun, May 29th

Recommended Posts

Dear all,

as suggested by Hughsie, here's my pastel sketch my contribution to the solar imaging challenge. 

20190529_Sun_H_alpha_small.JPG.80842f359271cf0324a99c0a06592d9b.JPG

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

Like all of my astronomical sketches , I did this one directly at the eyepiece. The picture of the sketch is taken with my smartphone and just cropped.

Clear (and sunny) skies!

      I've just bought a Daystar Solar Scout 60mm DS for H-alpha imaging of the Sun. I am now looking for a suitable camera to use with it. I know I could use my DSLR, but for H-alpha that is not going to give best results, so am looking for a dedicated monochrome imaging camera. I have identified the ZWO ASI178MM as a possibility that fits my budget and has a large enough (I think) sensor to image the entire Solar disc if I use a 0.5 focal reducer which will give me a total focal length of 465 mm.
      Does anyone have any experience of this camera in this application, or know if it will be suitable? I know it does not have an IR blocking filter, which I understand is an advantage for H-alpha. The spec is available here:

      Thanks

      Hi all.
      I am looking for a zoom eyepiece to 60mm lunt. My first choices are Lunt zoom and Pantax smc xf zoom. Which will work better? Can you have any other offer? You could say something more about these eyepieces while observing h-alpha?

      I bought this filter about one year ago with the aim to protect both my Tak-100 DF and a Quark eyepiece which eventually I never bought. Therefore, I am selling it, hoping that it will go to a good home and be used as it deserves. 
      It is a top quality Baader ERF for solar viewing with Quarks. It is in excellent condition and comes complete with housing measuring 146mm. The previous owner used to fit it on an Altair 115mm F7 refractor. With some minor modification (essentially adding some padding to the internal side of the housing) it can be fitted on many other telescopes.
      It cost £550 but selling for £320 including postage. I will accept PayPal (pay as a friend) or direct bank transfer.
      Also advertised on ABS.
      Thank you for looking,
      Piero

      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:
