Also ; as the quality of the sky allowed it I tried to image the prominence in different wavalenghs..
I added the colors in order to give the same hue that I saw in the eyepiece...
The Helium line was rather faint ; the H beta was quite briliant and well defined. And the H delta was rather hard to image and a bit ghostly but still visible..
PS : notice the varying degree of definition increasing when the wavelengh shortens.

Terrific comparison of the prom in the different lines. It looks like Hbeta is a good one for proms!

thanks very much but when you see it live you realize how strong the emission in H alpha is : its so much briliant!! no wonder its the line used most frequently.

Re: prom of the day May 31st 2023 with spectro
how did you find(identify) H-delta
would like to try with SHG

its in the blue region of the spectrum and the prominence is also pretty bright so you cant miss it but try first with a slit not too wide to find the reversal of the line .
