NGC188 is most closest DSO to then North Pole what I ever imaged. This adds some charm to NGC188 open cluster.

Details about object

NGC 188 is an open cluster in the constellation Cepheus. Unlike most open clusters that drift apart after a few million years because of the gravitational interaction of our Milky Way galaxy, NGC 188 lies far above the plane of the galaxy and is one of the most ancient of open clusters known, at approximately 6.8 billion years old. NGC 188 is very close to the North Celestial Pole, under five degrees away, and in the constellation of Cepheus at an estimated 5,000 light-years' distance, this puts it slightly above the Milky Way's disc and further from the center of the galaxy than the Sun.

Great image! Very nice cluster, too! I've visited it for the same reason --- just because it's ~up there~    Tom

I first learned of this cluster in the late 1960's from a Walter Scott Houston Deep Sky Wonders installment in Sky and Telescope. Fond memories, thanks for bringing this up and great picture! It is a dim cluster.

Funny coincidence, I just observed this one last night in my 40mm handheld refractor at 12x. I've seen it before, but that was several years ago. It was fairly easily seen as a faint glow in the 40mm. 

 

 

Clear skies!

Hi, Sergiy,

 

great result! waytogo.gif

Is it still necessary to guide (near the North Pole)? laugh.gif

 

greetings

Andreas

Hello Andreas, there is no reason for guiding smile.gif except that you want to dither between frames (my case). During capturing I realized that each dithering operation near the Pole takes long time (~ 30 seconds).
