Spectra data of PN acquired with Alpy as reference
Posted: Sun Mar 26, 2023 12:59 pm
Dear community,
I am running a school obvervatory in the city of Langenthal Switzerland (*), of course under light-polluted skies. This year I am happy to coach again a high-school student who wants to study planetary nebuale (PN) for his final thesis.
In 2016, I bought an Alpy 600 spectrograph from Shelyak incl. guiding and calibration modules, but only used it for first steps taking star spectra. Two years ago another high school student used our SA-200 grating for her final thesis. We will mount the Alpy behind a 36-cm RC mirror (f/8). We have a focal reducer and also recently purchased two extra slits (10 and 50 micron) to experiment with higher and lower resolution (R) than with the default 23 micron slit that comes with the guiding module. We will use Demetra for data acquisition and processing.
Question: would anybody share for training purposes their spectral data of PN acquired with such an Alpy spectrograph?
We havn‘t had the time and good weather yet but plan to record spectra of suitable and interessing PN (different excitation classes) over the next 3-4 months.
N.B.: for people with some background in physics, I can highly recommend the book „Physics& Dynamics of Planetary Nebulae“ by Grigor Gurzadyan, Springer-Verlag 1997.
Many thanks in advance and clear skies
