NGC7000



After raking the fall leaves as a small boy I use to spend time daydreaming and looking at the clouds - forming familiar shapes of animals and objects - usually from the books that I was reading or from places we visited.  The same way I use to daydream as a child – I find myself “night” dreaming while at the telescope.  This one reminds me of a palm tree bending in the oceans breezes.  As an “older” boy now it is nice to remember those younger days. 

This photograph is a small 22 x 30 arc minute view of the North America Nebula.  NGC7000 is a  emission nebula located in the constellation Cygnus close to the star Deneb and about 1800 light years distance.   This dim nebula is quite large covering an area larger than four full moons and was discovered by William Herschell on October 24, 1786.
