a way to center and observe UV lines in spectroscope

[highfnum]

Now that I have a spectroscope, Helios-graph
I was wondering how you guys center caH or caK lines
my eyes don't see these very well

a While back I wrote about caK eyepiece with use with my Lunt caK scope
I tried it with spectroscope a low and behold I was able to see many UV lines
including caH caK

view is green with black bands -
its not very bright but bright enough that I can see them

here is my UV eyepiece

here its in my spectroscope

i took image of line I believe are caK and caH lines
if I'm wrong please state

i must be right
here is caK and caH images - raw and unprocessed
Montana - this is my first caH narrow band image - not that 5A filter stuff

again I can't thank all of you on this forum for me getting this far
with SHG

I got to start reading Wah! document on processing images!!!
Wah! , Merlin66 this type of image processing is more similar to long exposure imaging
than planetary

one question based on spectrum image above can you Identify how is K and who is H if you dont know orientation of camera?

[highfnum]

caK i think? well the its the other line
real cool - lines are close enough that one avi file has both!

yes they are!

it's easy to catch them with the camera : end of blue spectra!

part of avi seq that shows cak, cah bright area in spectral lines
very spooky how this all works to me

Let me process it.

Very interesting indeed!

[highfnum]

im making progress

Mark your next!!

[marktownley]

yup

[p_zetner]

Congratulations on your progress.

Cheers.

Thx peter
today I took a few more
they are better
I got to learn proper post processing
