Re: pi Aqr V/R and EW monitoring
Here is my time lapse of 9 observations of pi aqr h alpha profile with Atik 460 mono C14 Lhires III 2400 l/mm grating from 02-08-2019 to 10-01-2020. I think this is an effective way of showing changes in spectral profiles over time. Many thanks to John Paraskeva creator of BASS for his help in creat...

I plan to make an animation of my observations, this should be interesting showing a 4 year period, but need help in doing so. H alpha monitoring of vv cep continues, as w...
