Hi,

attached two new animations. They show the relative quiet chromosphere from 5.9. on the western edge. I have enlarged the interesting part . Especially, I like the place , which I have marked with the red arrow. It looks like looking into a saucepan with molten iron. It when you moves away a little from the screen is best.

The second animation shows the large protuberance at rest on the west side. In the foreground is a small relapsing eruption and the response to it , as it meets the chromosphere. I have this animation contrast enhanced for better visibility and also in a negative light.

thanks all for your answers.

Thanks for the feedback. I am currently thereby switch the optical path of the telescope on a collimator path of rays. However, the results are far worse than those with the telecentric. I will continue to report.

Hi Harald - just amazining animations! :bow:

I am currently thereby switch the optical path of the telescope on a collimator path of rays. However, the results are far worse than those with the telecentric.


Inspired by you and a few others, I am designing a larger solar telescope - a 150 mm diameter mirror-based design. I have discovered that using a collimator lens designed to focus light from infinity (in my case a 100ED refractor lens) will introduce a great amount of spherical aberration if used as collimator lens. The collimator must image a pupil lying at the objective, not infinity.

In my design this was completely eliminated by under correcting the primary mirror to an oblate spheroid with a conic of 4.0.

Spot diagram analysis: Top spots with a parabolic primary (conic -1.0), bottom oblate conic 4.0 -- now diffraction limited over more than half a degree!

Well Bob that looks like a very interesting project! Hope to see its outcome soon.

Needless to say Harald, your images are always the best in the world of amateur photography of the sun :bow:

Hi all,

thanks for your answers. Bob : your project is very interesting. Today I have the optical design integrated back in the grid tube. It is longer than the previous design. I am currently using two Cooke triplets and one achromatic lens to make the beam parallel and to enlarge the image on a focal ratio of 1:50. It was obvious now that rain has been predicted for the next day.

Luca: I hope that the new Unigraph (300/3600mm FH )will bring even better Performance in the next year.
