You can convert DSLR raw to fit using IRIS which ISIS will read. (make sure you set your camera model in IRIS so the debayering is done correctly) Wed, 22 May 2013 16:03:44 GMT Hansen Torsten http://groups.yahoo.com/group/staranalyser/message/2923 http://groups.yahoo.com/group/staranalyser/message/2923 Hi François, thank you for your comment! An impressive collection of spectra you have got there! Congrats! Some informative lists of stars, too!

Lot of people, some from this list which I was very pleased to meet.

The results were OK for a first attempt, I am very pleased with the Star Thu, 16 May 2013 02:30:42 GMT Ed Wiley http://groups.yahoo.com/group/staranalyser/message/2920 http://groups.yahoo.com/group/staranalyser/message/2920 Thanks Ken, I think I will process with ISIS, free and seems powerful.

Welcome to the Rainbow side..... The next interesting step is to process and analyse the spectral images......... ... -- "Astronomical Wed, 15 May 2013 01:06:19 GMT Ed Wiley http://groups.yahoo.com/group/staranalyser/message/2918 http://groups.yahoo.com/group/staranalyser/message/2918 At the TSP I hooked up the Star Analyzer to a 135mm Zuiko lens on my XT. Took a bunch of 5-20sec exposures with the camera mounted on my Kenko Sky Memo.

I began such a survey two years ago. See for instance EW evolution in R Leo (in the midle of the page ) : Mon, 13 May 2013 17:09:19 GMT staranalyser http://groups.yahoo.com/group/staranalyser/message/2916 http://groups.yahoo.com/group/staranalyser/message/2916 Hi Manu, Your spectrum looks more like a Wolf Rayet star, for example Gamma Velorum http://www.physics.adelaide.edu.au/~pmcgee/wrspec.htm Are you sure you have Mon, 13 May 2013 16:53:47 GMT Hansen Torsten http://groups.yahoo.com/group/staranalyser/message/2915 http://groups.yahoo.com/group/staranalyser/message/2915 Hi Robin, thanks for your comment! It would be very interesting, at which time after Maximum the H-emission will cease. This star might be better positioned Mon, 13 May 2013 13:10:42 GMT Terry http://groups.yahoo.com/group/staranalyser/message/2914 http://groups.yahoo.com/group/staranalyser/message/2914 ... Dear Manu I think there is a problem with the spectra. I have taken a few spectra of Eta Car with my LISA spectrograph. This is higher res than a star Sun, 12 May 2013 20:55:54 GMT Ken Harrison http://groups.yahoo.com/group/staranalyser/message/2913 http://groups.yahoo.com/group/staranalyser/message/2913 Manu, Hmmm Something wrong.... The attached image is a spectrum by Terry B which shows the "normal" emissions. -- "Astronomical Spectroscopy - The Final Sun, 12 May 2013 13:19:12 GMT Emmanuel Jeffredo http://groups.yahoo.com/group/staranalyser/message/2912 http://groups.yahoo.com/group/staranalyser/message/2912 Hi all The spectra of Eta Carinae, but I think that there are a problem with the calibration. There are some ionized carbon around the star ??

I was watching the brightness of Chi Cyg rising (It looks like the maximum might be brighter than average) and wondered if anyone Sat, 11 May 2013 17:35:23 GMT Hansen Torsten http://groups.yahoo.com/group/staranalyser/message/2910 http://groups.yahoo.com/group/staranalyser/message/2910 Hello, it has been quite some time, when I took my last spectra. This evening (2013, May 06), I also wanted to test the suitability of my C5 for spectral
