Hello,

I am glad to share with you the first light images taken with my new 300 mm Newtonian solar telescope :

That is so cool.

 

Maybe once every couple of years I will get perfect seeing and in my 10" (254mm) Newtonian with full-aperture Baader solar film, I can see details in the sunspots that I have never seen well even in professional photographs. I just assumed it might be artifact on my part.

 

Your images show it. The salt and pepper umbra (as I called it in my log) with the penumbra sending streamers leaning into the umbra, many capped with one of the salt grains.

 

Newtonians can be great solar scopes.

 

George

Thanks a lot :)

 

Georges : the visual observation of the solar details is fascinating when the seeing is favourable.

 

Harald : the work and achievements of Art Whipple were a source of inspiration to me.

Christian, it's not just your equipment and raw image, but also the way you got the full dynamic range to show up in the jpeg file. Congrats. George

Thanks !

Here are the measurements of the seeing with the SSM during part of the observing session (first graph) and during the acquisition of the first image (second graph, 0.45 arcsec average over 30 s) :
