| Mount: | Losmandy G-11 |
| Imager: | SBIG ST-7 non-E non-ABG |
| Image Details: | The top image is a single
4 second drifted (unguided) image of Regulus' spectrum using the Rainbow Optics
transmission grating threaded into the nosepiece of the ST-7 imager. MaxImDL was
used to take the image and process the data. Calibration was done using
VSpec software. The values are CCD image intensity vs. Angstroms.
May 5, 2001. The second image was taken on 17-March-2005 using a grism on an ST-8XME NABG imager through a Tak FSQ-106n at f/5. The image has been frequency calibrated and corrected for instrumental response using VSpec software. |
