Hello from Winnipeg, Manitoba, Canada.

Hello Everyone.
Greetings from Winnipeg, Manitoba, Canada at the geographical centre of the North American continent. I am a recently retired physics professor and am pursuing my lifelong interest in astronomy. In the last couple of years, I have devoted a considerable amount of time to solar imaging and spectroscopy with a homebuilt spectroheliograph based on a converted surplus Czerny-Turner spectrograph. An article describing some of these studies was recently published in the online Journal "Spektrum" (v.52) of the Vereinigung der Sternfreunde:

I am very much interested in stellar spectroscopy and am designing / adapting equipment for that purpose. I currently have an adapted Oriel MS125 spectrometer (eBay purchase) which will be coupled to a Celestron C8 and brought into action this coming observing season. This system has been bench tested using a mercury line source and demonstrates a spectral range of 2200A across 1600px with R~1300 for 25micron slit and 1200 l/mm grating. Other gratings can also be used and I look forward to experimenting and learning from this group about desirable choices. I am also constructing a high resolution system (R~50000) for detailed study of stellar H-alpha lineshapes as well as a low resolution system based on a Wollaston prism interferometer. I tend to enjoy designing and building instruments but will try to discipline myself to get outside regularly and make observations!
I find the ARAS Forum very active and informative. I'm very interested in learning which stars are good candidates for continued study and at which spectral resolution levels. I am especially interested in Be and other emission line stars. Hopefully, by the spring / summer 2018 I can start posting results!
Regards.
Peter.
