Here’s a pretty good example of light pollution:
This drawing was done from my moderately light polluted backyard
There are about 5 street lamps around my house
This drawing was done from my dark site 20 miles away

both of these are M22 found in Sagittarius.
as you can see the effects of pretty dramatic.

The town I live in is moderately sized about 35,000 so the light pollution is not horrendous as it is in large cities but it still bad enough to make a huge difference.

M22 In Sagittarius

This is M22 found in Sagittarius This is one of the “EASY TO FIND GLOBULAR CLUSTERS“.
You can see it with a set of binos very easy.
From a dark site I rate this better then M13.
It is truly a spectacular globular cluster well worth the time to hunt down and study!

This drawning was done using my 10 inch DOB with a 15mm 84x

Log Book

This is a the log book format that I am using, you can download it HERE
One of the best things you can do is to LOG EVERYTHING YOU VIEW
I can’t tell yo how many times I have looked at a star chart and say “yes I have seen that” but never logged it.

And it does not count if don’t log it!

I got some more scope time in last night.
It was not the best viewing but its better then nothing.
I have been looking for M10 and M12 in Ophiuchus for a couple of weeks now and last night I FOUND M10 I could not find M12 thru all of the ground haze!

M10 was discovered 1764 by Charles Messier.
and is a 7th mag globular cluster.
It is 14,300 light years away from us!
