This was just a 300 s raw exposure uncalibrated, no dark or flat frames just to check if the h alpha line has changed.

The response I am waiting for is if you are able to do a comparison between the spectra obtained by Marc and my spectra, as taken with Marcs C11 and my C14.
Please refer to Marcs previous post for info.

In our last communication I measured the resolution and inserted it the fits file.
I have posted a png file of my latest ‘quick’ spectrum of the h alpha profile of vv cep.

I am awaiting Robins response on this one.
Also, just a minor point to resolve before I can upload spectra to the database.

I am keen to submit my data for further analysis as suggested by Marc, BUT I use BASS not ISIS to do my data reduction.
Thank you for your input, any further comments welcome.
