Welcome
Welcome to the spectroscopy forum. Your comments, suggestions and questions regarding spectroscopy are welcome.
Currently I am using a Lhires III spectrograph with a 2,400 line/mm grating on a Meade 12" LX 200 GPS. This seems to be an ideal combination for observing epsilon Aurigae. For those observers who do not want to invest in an expensive spectrograph, a Star Anaylser provides a great way to do low resolution spectroscopy for under $200. The up coming Workshop at the Adler Planetarium in Chicago on 7 August will discuss these two spectrographs in detail.
Hi Kevin, You certainly can do some low resolution spectroscopy that can be of value. Particularly on epsilon Aurigae. I will be covering this in the Workshop in Chicago. An example is the low resolution gives you a picture of the whole visible spectrum. My high resolution work can only look at a 90 angstrom wide windowwhereas the visible spectrum is some 3000 angstroms wide. The low resolution work can alert others to zero in on a region that is changing. Also, the majority of the work with spectroscopy is the processing. It is similar for both low and high resolution work, so mastering the low resolution will be a large accomplishment. For more information on what you can do with the Star Analyser, check Robin Leadbeater's web site:http://www.threehillsobservatory.co.uk/astro/spectroscopy_11.htm Good luck! <!--StartFragment--><!--EndFragment-->Jeff
Thanks Jeff!I am looking forward to your presentation, and will check out the aforementioned website.Regards,Kevin
Hello Jeff,I'm very much interested in doing spectroscopy. What kind of "stuff" can you do with low resolution spectrographs? Would the Star Analyser be a worthwhile investment to learn more about spectroscopy? Would the data I could collect with a low resolution spectrograph be useful for this project? $200 would be a lot more feasible than the $2000 plus option!Regards,Kevin
