The weather is starting to get cooler, so I am getting back into Astronomy.  I realize I haven't really posted much of my other passions, so I thought I would share and hope to draw out my other fellow closet Amateur Astronomers. 
 
Here is my new setup:

14" Dobsonian.
 
Some pictures of what it can do:
See the island in the middle of the picture? (1100 feet away)

 
Here it is at the minimum magnification:

Tree top
 
Left side of the island:

see the rock at the bottom left corner?
 
Lets go to max magnification with what it comes with (no barlow):


 
Here is the high tension wire tower behind the island.  About 1.5 miles away:

Max magnification.
 
See the red arrow?

thats a light fixture at 500 feet.  It was the closest object I could see with max magnification.
 
Want to see who makes it?

Good ol' GE
 
 
 
Now on to some "Astrophotography." I use the term loosely, because I used a cell phone held up to the lens.  It is a pretty high speed cell cam as you have manual control over many functions, which has allowed me to take the following pictures.
 
The moon/lunar surface:


 
 
The Pleiades:

 
Polaris:

 
And one of my favorite objects to see:

Can anyone guess what it is?  
 
Please feel free to post whatever you like on the subject.  I am planning a Messier Marathon next weekend in the Catskills NY.  The only "blue zone" in 300 from my house (minus going out to sea)  
 
What to see how bad (or good) your location is?  Have a look here:

    Nice  always something i've been interested in but never got round to the investment side of it, we get some really clear skys where i am in Scotland, only 300 houses in the village i live so not a lot of background light.
     
    my guess to your picture is where the big asteroid is heading towards us?

    I have a Celestron Celestar C8 and 2 Meade C90's. Recently played around with the C8 with a T-adapter for some moon photography. Had the C8 since the 90's (I think). Not messed with the Meades at all. Got the Meades for next to nothing from Goodwill. Goodwill is like playing the lottery with camera and telescope parts. Buy four things for almost nothing and one tends to be a real gem. It turns out so cheap the the 1:4 is still cheaper than ebay by far. Seem to be a solid tabletop scope though.

    I am thinking of machining a tube that allows a DSLR to slide into and up to the eyepiece.  I know most folks take off the camera lens and use the telescope as the lens, but at the cost of a single aluminum tube, a night on the lathe, I thought it would be fun to experiment and see what the camera can do with both its telephoto lens, through the telescope.

    I am always interested in celestial events/things. I don't own a telescope, wish I did. Where I live is a pretty good view on the edge of a city. Interesting thread Nateman!!

    Nice thread! I don't own any of that sort of hardware alas.
     
    As an aside I'd highly recommend The Planets show for any astronomy enthusiasts, the first season just ended. So much brand new stuff on the planets (and exoplanets) that only just came out within the last couple years it was fascinating to watch. Former NASA astronaut Mike Massimino hosts it.

    Made a thing.
     
    It mates a DSLR camera up with my telescope:
     




     
    Still have to test it out.

    That is very cool Nateman, as always....The inner surface of the cylinder doesn't matter does it? I'm wondering if blacking it out may help. It may not matter because you have the important part taken care of. Very cool, you always find a way to get things done, impressive!

    What do you mean about the inner surface of the cylinder?  you did bring up a good point... I should probably paint it matte black, but the tube itself blocks any direct lighting.  Perhaps the interior can bounce whatever light in weird directions, but I plan to test it out friday night out in the woods with no lights anywhere. 
     
    But for you... I will paint it ;)

    the above got me thinking.  I just sat down and identified everything that I could see in the picture.

     
    You guys are welcome to DL the picture and add to it.  Can't seem to identify Perseus or Pegasus in the picture with this many stars.  I just used paint

    The Double Cluster:

    (high res:https://i.imgur.com/tgeHPwC.jpg) - so many different color stars.
     
    The Orion Nebula:

    (high res https://i.imgur.com/Gul254h.jpg)
     
    These were taken with nothing but the camera by itself.  Planning on hooking up the camera to the telescope itself.  Adapter is arriving today, but without tracking on my larger telescope, I am stuck with moon pictures.

    I really like this thread! I have my hopes up that I may get a telescope for christmas. Fingers crossed.

    The fiancée will be getting a new Mac Book Pro for school, and doesn’t know it yet.

    Re: The Astronomy Thread 2017/11/27 10:55:15 (permalink)
    What kind are you looking for?  
     
    Funny story...
     
    I was on an astronomy forum and I found an slightly used Orion 8" reflector.  It retails for $250.  Its down in Virginia, so I debate on driving down there to pick it up.  He says it will be about $70 to ship to Jersey.  I calculate about 18 miles per gallon (not even tolls) and I get around $71 for me to drive down to get it.  So I say whatever... ship it.  Also the $250 telescope comes with mounts and dovetails, and for a few extra I get some fancy lenses.  All told I ordered (retail) about $500 worth of gear, and I pay under 300 shipped.
     
    So the box arrives and its rattling.  Never a good sign when dealing with precision instruments.  I open it up and I see the primary mirror came loose and was thrashing around in the tube during the trip.  Scratched up the primary mirror, the tube, chipped secondary mirror and bent the hell out of the paper thin arms that hold the secondary mirror in place.  BUT the good news, is the lenses are ok.  I take pictures and email the guy that it was destroyed.  He told me to keep it, and refund my payment.  He will deal with filing a claim through UPS.  So I think to myself I acquired 2 free lenses (each retails for $70 or so - one being an illuminated reticle) 
     
    So I take the telescope downstairs and get to work on assembling it, straightening out the arms take it outside and it works!  Brought it back to life.  Its probably operating +/- 90% of its normal light gathering capabilities due to the slight bends in the secondary mirror arms, and the scratches on the primary mirror.  But after collimation it actually still works.  Free 8" telescope.  
     
    I got it for dedicated astrophotography.  Now I have to purchase an equatorial mount for it.  
     
    I took this through my 14" Dob https://i.imgur.com/Vz5ekya.jpg  But without tracking, the star trails are always going to appear.  This was a 1 second exposure.  Thats why I need and equatorial mount.  But I dont think I can fit my 65 lbs telescope on a mount without paying thousands.

    honestly I haven't even seen Neptune or Uranus either.  I mean I have "seen" them, but i haven't really paid attention.  With a 14" telescope sometimes finding faint planets its almost a hindrance.  the telescope gathers so much light that you see SO many stars, and its hard to pick out the distant planets from the stars.  From Saturn in its cake.  But I also didn't really put much effort into seeing them either.  I cannot WAIT until Jupiter is visible in the night sky.  I have been dying to see what it looks like with this scope.  
     
    Also never saw mercury in my life.  I would like to change that one day.

    Dear god that is a nice setup!!  What kind of mount is that??
     
    I am looking to get an Orion Atlas mount second hand.  Has a 40 lbs scope rating.  I am trying to get my 65lbs 14" dob down to that weight.  Its proving challenging designing my own telescope.  Looking to build my own home observatory.  
     
    Get that beautiful sucker outside and take some pictures already?!
