Re: my first caH caK with open slit spectroscope
woooaw!! really!!! thats really are amazing results!!!
How did you manage ? I tried yesterday with my grating blazes at 412nm for the UV and I couldnt get anything altough there were nice prominences!!
Did you have to refocus the collimator for UV (shorter focus lenght) ? did you have to remove the protective filter of the camera ?

Re: my first caH caK with open slit spectroscope
i was a happy man today
a) look for prom in Ha
b) move grating to caK and H line
c) refocus primary scope so image focused on slit
d) raise exposure and gain on camera I used asi290mm until you see something
Did you have to refocus the collimator for UV (shorter focus lenght) ?
No just the primary telescope focus
did you have to remove the protective filter of the camera ?
No asi 290mm can "see" UV (at least a bit passed caK (I did plenty UV with SHG)
Thx
