Dear all,
Last year in France I took spectra of HD290380 because of an AASVO alert concerning an eclipse by a planet/brown dwarf.
Only last evening I could take another one...... the green one is last year.

The SNR is very low (magnitude>10) but the difference is obvious!
Cheers ...

HD57682 emission event
Hi all,
On the 4th of jan I had the luck of capturing an emission event on HD57682.
There is a request for spectra for BeSS - the observation period has been changed to 6 days!
Cheers Arnold

Re: reading 1D fits files
Great Tim!
Much appreciated
and thanks for sharing your code. Although I will be using vb, this will certainly help!
Btw, in my program I added:
If NAXIS>1 message "not a 1D spectrum" to avoid loading a 2D fits file
Regards Arnold

reading 1D fits files
Hello all,
At the moment I am busy making a program to model line (Hα) profiles....
Can anybody tell me how to read a 1D fit(s) file in VB?
Now I am using the .dat files generated by ISIS, but it would be nice to be able to read the .fit.
Regards Arnold

Hello everybody,
My name is Arnold de Bruin. I have been busy (off and on that is ;-) ) with astronomy for almost twenty years and since two years really found my "thing" with spectroscopy. I do have the SA100 and SA200 but more or less dived in buying the L200 when I discovered it was being build ...
