AG Peg for 2015-08-23 from 4270 to 5420 (R=6400) compared to my last result for this range on 2015-06-30, near its maximum.
Flux calibration based on the standard star HD209459 Vmag = 5.75.

Hi Steve,
Your spectrum looks very good. Nice IR in the blue part.
Your spectrum is welcome in the data base (fit format, send it to francoismathieu.teyssier at bbox.fr)
Best regards,
François

Hi,
after shooting AG Pegasi by SA200, last Thursday we took the spectrum of the variable star by Dados 200 l/mm. The attachment shows the profile in the bandwidth 4800-6600 A, without correcting by istrumental response.
Celestron C11, Atik 314l+, 10Micron Mount, 8 frames x 300 s., dark, bias, flat. Dispersion is 1.4 A/px.
