Hello,
today i've decided to go a go at iNTI from Christian BUIL with SolEx.
So I tried iNTI with my spectro-coronagraph... Here are the first results that for once looks like the current sun
Also the nice prominence of the day with the spectro coro
600 lines/mm
1200 lines /mm
1800 lines/mm
and 2400 lines /mm : the doppler effect show the spicules and the velocity of the different parts of the prominences.
Here it can be clearly seen that a part of these prominences is arching over the chromosphere . The 2400 lines gives (in this case more information about the little prominence on the left )

Hi Chris,
Excellent. Do you have different disc sizes or do you move the disc in and out according to the Sun size.
Where is the disc exactly placed ?

Hi rsfoto
I have different sizes but as there is no motor its best not to use a disk that matches the sun perfectly : otherwize keeping the sun hidden becomes very hard as it will have to be more precise (wich is almost impossible by hand).
"Where is the disc excatly" : have a guess.... everything was explained in the link I posted about the making of a spectro-coronagraph. It's also the same of every spectroscope.

Great to see you tinkering to get a full disc
