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...
After lots of reading, I'm getting ready to try to capture my first spectrum. I'm in Seattle, Washington (State) which has London-like weather: lots of...
Hi Tom, If you stick to bright stars to start with (brighter than say mag 4) you should not have much trouble with noise. Make sure you image the right...
Thanks, Robin, for the detailed and helpful response!! I'll let you know how it goes. I'm off to California tomorrow to a Meade 2-day conference on their...
... bright ... Well you could chase a total eclipse like I did ;-) http://mysite.wanadoo-members.co.uk/astro2/spectra_27.htm Or you could try a similar setup...
maybe you can asking for kit pst I see on the web I do not remember wher somebody dismantel a pst and put it back on a bigger scope for more resolution and it...

Hello everyone, I did some more imaging and would like some comments on the file mentioned below. Have I got the O2 lines correctly ID'd? I think they are the...
Robin, I've also had a chance to work on the image I got for Beta Grus. It's a M5III class. The PIC file has been processed similar to your recent posts, with...
Hi Mark, There are 3 sets of Telluric lines between 6700 and 7700A. They are rather broad though as they are each made up of several lines. See Christian...
Hi Mark, I've not written one for that stage yet but I can talk you through it. Firstly though I have noticed quite a big focus change in your spectrum from...
Robin, thanks for your help. I'm at work so it will be a while before I can try these steps. My scope is an ED80 f7.5 mounted an a HEQ5 mount, the SA is...
Robin, did those steps and I can see where I was going wrong. Have got a spc file of the response ready for the next stage. I'll do some more reading of the...
Excellent, we are now ready for the next step then. If you look at your instrument response curve you will see features in it which are in the library...
Robin, much thanks for your help. I got through the steps OK, and it seems to be working out! Just a couple of questions though: 1. While the CCD + SA +...
Hi Mark ... That's the idea. The only other variable is the extinction due to the atmosphere. When I am looking for highest accuracy though I look for a star...
Hi all, I have a question relating to using the spectra of an extended object like an edge-on spiral galaxy. If the recorded spectra was big enough, would it...
Hi Mark, This is a fascinating experiment. You can prove that dark matter exists from a plot of the rotation speed of a galaxy against distance from the...
Hi all ! I collected the image of Gamma Pavo a few nights back and after going Robin's very helpful instructions, I think I've managed to process it correctly....
Hello - been absent for a while spectrowise but at http://www.cloudynights.com/ubbthreads/attachments/1913765-spmix071015z.jpg are some spectra via my 30cm SCT...
Hi all, does anyone have, or could point me in the right direction, to get a listing of the WR stars containing constellation, RA, DEC, magnitude? cheers Mark...
... Mark, if you just Google /WR stars/ you will see many WR links with lists. Its easier to answer this way that list all the links. Hope this helps - Jerry...
Mark, Go to http://astrosurf.com/aras/wr/wr.htm ; there is a WR catalog at the bottom in miscemaneous format. Otherwise, all professional catalogs are on CDS ...
