unfiltered and comparisons

Forums Variable Stars Valid filters for photometry? unfiltered and comparisons

Dr Paul Leyland

That is also my belief.  Unfiltered magnitudes also correlate very well indeed with Gaia-G magnitudes.  This should come as no great surprise …

That’s why I generally quote Gaia-G magnitudes for objects on unfiltered images I’ve taken.  Please note, these are NOT images taken for photometric analysis, for which I almost always use V or Sloan r filters.
