Hi Chris, Welcome to the group. To suplement the tutorials on the visual spec website I have written a quick guide to producing a spectrum plot using vspec to...
Hi Steve, If you look on my website here http://mysite.wanadoo-members.co.uk/astro2/spectroscopy_5.htm you can see the response curve I got for my setup using...
Hi again Robin Sorry for the delay replying. I have loaded two files to Steves File/Response folder. One is a response curve I made using Altair and divided by...
Hi Steve, They do look rather odd. Can you upload the two original fits images and your final response curves in spc format and I will work through them using...
Hi Robin Uploaded the files you asked for in Steves file/Response folder. I`d be very interested in your findings. I must be able to recite tutorial 5 off the...
Ok...... My results are in your folder I started with the fits images and calibrated them from scratch. I used the H alpha and H gamma lines to wavelength...
A mega thanks for that info Robin. A lot to take on board and I think I`ll have another go from scratch with some other stars and try and get that processing a...
No problem Steve, I should not worry too much about getting a super accurate instrument response, just be aware that it has an effect on the broad shape. It ...
Thanks to Olivier at Shelyak instruments http://perso.orange.fr/shelyak/fr/ there is now a French version of the Star Analyser instructions. They can be found...

Hi Folks I`d be interested to see which stacking software others are using for their spectra and how they use them. I seem to have a bit of a dance every time...
Congratulations Dez, This may well be the first amateur spectrum ever taken remotely using a robotic telescope unless someone knows different. I will be...
Hi Steve, My path is fairly convoluted too, probably not the most efficient but it uses the software I am used to for each step, it preserves the information...
Hi again Steve, ... wrote: Since ... then ... It is good to try to stick with 16 bit "eg fits or pic" files throughout the processing if possible. There is a...
Hi Robin Thanks for the info. As you may remember I use a DMK firewire camera and very pleased with its performance having the option to save the shots as...
... I know several people who have been testing robotic systems and snagged a few spectra just to test the possibility, with an SA grating in the filter wheel....
... Is there any English version of TeleAuto? I thought I read you could change languanges under File but when I tried its French only ?? Maybe Im missing...
Hi Jerry, You need to download the English dictionary file here http://www.teleauto.org/DownloadEn.php and instal it in the same folder as the program. You can...
baader add 2 page for there grating but the real interessting is the table of target http://www.alpineastro.com/Eyepieces_Accessories/Spectroscope_Manual.pdf ...
Thanks Jaques, If the Baader system is capable of meauring those targets then they should also be suitable for the Star Analyser and will add to the list in...
Hi Jaques, Yes the SA is 100 lines/mm. This is deliberate. It is because it has been designed for easy use with small CCD cameras like webcams and low cost...
curious but I read the text again and again and it look like it is for argentic film only they do not speak about digital they do not soec about any computer...
Hello all, I have just recently received my star analyser. Home for me is 80klms south of Sydney. I'm using an ED80 refractor with a meade dsi to image and I...
Hi Mark, Congratulations on your first spectrum. It is good to see a Southern Hemisphere target. It is better to try to keep all processing at 16 bits as...
Robin, thanks for the comments. I managed to get a number of spectra on the first night including the glob cluster, 47 Tuc, but I'll have to do it again when...
