Hi every body,
I was on holidays on the Loire river during 2 weeks ; i only observe during 4 nigths, the other was or cloudy either light polluted.
About the Bortle pages : as these are of common usage, not depending of the observation type ( DSO, double, meteor,…) why not edit a Bortle scale booklet with all the different levels from 1 to 9 ? The 9 different levels will be an help to show the effect of liggt pollution to nom astronomy minded person.
"In addition to the original Ursa Minor, Octans, Orion and Scorpius, I now also cover Crux, Cassiopeia, Pegasus and Leo. This covers the poles, a mid-latitude constellation for every season, and two prominent circumpolar constellations (Crux and Cassiopeia). "
Obviously not every constellation is necessary , only the every season main ones.
Like this it will be a complete help for observing guide.
But it is your book, do it aa you like and even like this , we have to thank you for these opus.
