| Neptune Spectra 2018 November 18th by Christophe.P |
Here are my first experiences with low-res spectra on Neptune. These are calibrated and corrected data by dividing the raw spectrum of each planet by the raw spectrum of a nearby solar-like star (details are on the sets). Original data is also corrected from offset, dark, and flat. Results look correct in that the Neptune spectrum is brighter in blue and Uranus slightly more in green. I have some more projects about this: 1) Try to obtain a full spectrum with IR part. This cannot be done by one shoot as there is an overlapping of the 1st and 2nd order after 750 nm. 2) Try to calculate BRVI magnitudes. This is quite more ambitious but it would be already more interesting.
