Hi,
I was able to shoot AX Per tonight and see below a graph of the spectrum.
What is the hump at 7056Å - 7062Å ?
Thanks Rainer

Re: Call for observations of the preoutburst phase of T CrB
Hi Rainer, Interesting. But the height of a line is a very poor measure as it depends significantly of the resolution at that wavelength. The measure of the equivalent width (EW) will provide more accurate measures. I suggest using plot spectra (Tim Lester), a very nice tool. http://spectro-aras.co...

Re: Call for observations of the preoutburst phase of T CrB
Hi,
Yesterday night eg. today morning UTC time I imaged T CrB. See below the comparison of 5 spectra from 26-07 to 10-08 and I ahve the impression teh emission lines 4640 and 4684 are stronger or is it just my imagination ?
Thanks for looking

Hi,
Another T CrB spectrum addition and so I have four now.

Hi,
Had a more or less clear night and here another T CrB spectrum.

Re: Lisa with QSI520i
Hi David,
Thanks. I will not touch it again and now focus on getting good calibrations testing different ways.

Lisa with QSI520i
Hi, I have a LISA and my camera is an old reliable QSI520i and I ahve followed as good as possible al installation steps according to the user manual. One thing bothers me a bit. According to the calculation the Neon emission Line should be in the position pixel 1167 but after hurs of trying to get ...

Hi Francois,
Thank you very much. Was the FITS header OK ?
Sure you may upload them as you said they are good
Thanks and regards Rainer
