le Nordiste

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.

In my message here above i don't correctly  express my idea.

Obviously the book contains alls the constellation DSO ; my idea was to get some Bortle map as  for the winter constellation Orion (page 43 & 44), but for some other constellations all around the year, i think Leo, Cygnus etc.

Waouh ! what a good idea even with my Celestron 25×100 binoculars, i will have so much to discover.

I appreciate the Bortle scale pages. Is it possible to have spring and summer constellations ?

I live nearby Lille (Northern France and the light pollution is a mess.

Hi, from north of France,

I  enjoy looking the Moon with my binoculars (25×100 Celestron).

I am satisfied with my drawings of craters; but I fail to draw the relief -the mountains or smaller- how do you draw them?

Thanks in anticipation.

Congratulations for this long term action.

Each 1th it's pleasant To get à program.

 suggestion : in the next édition, insert à cloudsweeper as gift.
