Visibility II / V
As described in the Messier 82 Supernova SN 2014J, you leave for the full moon. There was a worsening cloud of filming when filming, but seeing was better than in the last couple of filming.
I took 39col 1min exposures here and also made a photometric brightness measurement of the still image with AstroArt5 software. The supernova brightness at imaging was 12.7mag.
I will display a screenshot of the AA5 photometry specification if anyone happens to be interested.
I also tried spectroscopy on the supernova and imaged a 12.3 Star Analyzer 100 through a lattice. I am still at the lower end of the learning curve in the spectroscopy observations, but the results are still displayed. In lattice spectroscopy, the calibration spectrum is first taken from a known star, in this case the A-class star Megrez. In the Megrez figure, the Angstrom / pix scale is defined using hydrogen Balmer lines (figure), this same scale is then used in the Supernova image to define the elements. The SN image should have been stacked with significantly more still images to make the spectral shadows more visible and the calibration of the camera itself is still in the learning stage. I used the RSpec program for spectroscopy.
