Had a nice intro to spectroscopy last night using a new Star Analyser SA/100 grating filter. Not sure if the attached pics are correct but it was fun getting my " feet wet" . To keep it simple I used a DBK618 colour cam with a TSA-120 at its native focal length . I forgot to order a extra spacing, so to capture I had to place the star and spectrum {first order
} at a diagonal across the frame. Using Rspec later on it looks like I may have clipped it a bit on the stars I captured. Also with some of the stars it looks like my exposure settings were to low {?}. I just captured a 60 sec AVI of each star and ran it through registax and used RSpec. Hope to have Kens {Harrison, Merlin 66} books arrive in the mail soon to help
