A few more for the Messier colletion


I struggle with trees in my yard that obscure a large portion of my night sky. I setup my 14" telescope in one of the only areas that get to -30° dec or better and waited for my targets to clear the treetops. In most cases the target barely cleared and there are dark artifacts where the trees obscured rich star fields near the center of our Milky Way galaxy.

I really wanted to get all the Messier objects from my own house and in this particular spot I cannot see the North Celestial Pole (NCP), which meant I had poor alignment and instead of fixing I limped along in a rush to catch my window. That meant that most of these are unguided shots.


M70 is at a distance of about 29,300 light years away from Earth and close to the Galactic Center. It is roughly the same size and luminosity as its neighbour in space, M69.

A photo I've already done, but I have to shoot when the skies are clear. Here's open cluster, M23.

Next up is a tiny open cluster, Cl Berkeley 90, C 2033+466, Ocl 196 (ref - http://www.docdb.net/show_object.php?id=berkeley_90)

Astrometry.net (http://nova.astrometry.net/user_images/378121#annotated) didn't have labels for this, but I had identifed it via Cartes du Ceil's default catalogs and did find the above link and do see something faint.  This was more of a finding a guide star test.


Next up is another guiding test/time killer.  This didn't come out nicely at all, but here's NGC 6445, the Little Gem - or is it the Box Nebula? (http://www.cloudynights.com/topic/472894-confusing-ngc-object-naming/).


The last cluster I have shot before.  M54 is unique in the Messier catalog in that it was "Previously thought to belong to our Galaxy at a distance from Earth of about 50,000 light-years, it was discovered in 1994 that M54 most likely belongs to the Sagittarius Dwarf Elliptical Galaxy (SagDEG),[7] making it the first globular cluster formerly thought to be part of our galaxy reassigned to extragalactic status, even if not recognized as such for nearly two and a quarter centuries."

Finally as a special treat for you sticking with all these poor quality images, I present a rushed M17, 
The Omega Nebula, also known as the Swan Nebula, Checkmark Nebula, Lobster Nebula, and the Horseshoe Nebula is an H II region in the constellation Sagittarius. It was discovered by Philippe Loys de Chéseaux in 1745. Wikipedia. (ref - http://en.wikipedia.org/wiki/Omega_Nebula)
Here's my previous attempt in my 6"

And Via my 14", +Akule

Here's a recent shot of my scope and if you want to learn more ask +Akule


Lastly you can see all my Messier objects I've shot to day here - http://maphilli14.webs.com/mikesdeepskyphotos.htm
I have only 5 left to go!

I think I'm the kind of person who doesn't like strong opinions.  It doesn't matter if I agree with your opinion or not, it's not factual, it never will be 100% factual and I don't care for it.  That's probably why I hate politics.

I've always loved facts, provable facts of nature and things concerning science.  

Over time, I found that most facts are mostly reference and it was the creation of and discovery of new things that intrigued me.

"A good friend once told me you are our memory
without them we equal nothing
And all I can see is the place I wanna be
Suddenly my life was so free
Leaves at my feet, blown to the ground
their echoes are reaching my ears
Nights coming fast, suns going down" - A7x
