Hello again..
I could again ckeck on the bog prominence that i started to observe this morning....but this time , as I had more time to image the sun I (again) tried both gratings in my spectro coronagraph..and guess who won the resolution contest..?
I let you judge....

With the 1200 lines/mm the image is "squashed" that its more blurry as each point of the image is more stretched due to higher dispersion.....
This works only if you use the "wide slit method.

awwwwwwwwww thank youuuuuuuuuuuuuuuu
the first image is the one produced with the 600 lines/mm grating .... there is less anamorphose (almost none) and less dispersion so its sharper.
