Why 4.5 you ask? Well first, because I was trying something a little different last time I went out to take some astro photos. I had realized that I had an attachment that allows me to use my normal camera lens (18mm-55mm) with my 42mm camera projection eyepiece , which is not the way i normally set things up. I'll post some images of that and explain a little further down. And secondly , I didn't get to take as many photos as I would have liked to that night , because unfortunately my hand controller for my telescope mount decided to bite the dust. Partly anyway. I'll explain that further down also. *** <center>☯</center> ***  *** This is the star Sirius. So this is the first image I've taken with this setup , which is the NEQ6 equatorial mount , a 250mm Newtonian telescope , a Nikon D5300 with an 18mm-55mm Lens and a 42mm Camera Projection Eyepiece attached to that. As this was the first time i used this setup I wasn't sure how it would come out , but i think it actually came out pretty good. The outer edges of the image are a bit warped , but i think the center star came out pretty cool. Exposure 68.8s , ISO 400. *** <center>☯</center> ***  *** This is Alpha Centauri. Taken with the same setup as above. Alpha Centauri is the closest star to our Sun at 4.37 light years away. (Proxima Centauri is actually slightly closer ,but Alpha Centauri is usually the one named as the closest). Exposure 68.8s , ISO 400. *** <center>☯</center> ***  *** The Southern Pinwheel Galaxy. My first shot of a galaxy woohooo yeah! Now , I get that the image isn't the greatest , but i just think it's really cool to photograph another galaxy man! It's a start , and i hope to be able to take more of these in the future when i get everything set up a bit better to where i can take really long exposures. Exposure 119.1s , ISO 400. *** <center>☯</center> ***  *** This is the star Canopus. One of the brightest stars in the sky along with Sirius and Alpha Centauri. With Sirius and Canopus usually being the first things that you see when it starts to get dark , well at this time of year anyway. *** <center>☯</center> ***  *** <center>☯</center> ***  *** <center>☯</center> ***  *** <center>☯</center> ***  *** The previous four images are all of Omega Centauri , and the reason i posted all four of these is because i seemed to have caught something in the background there (or foreground as the case may be, relative to Omega Centauri anyway). In the first image you can see it all the way on the left edge , and it's height in the image being around the top of cluster itself. It is just a line in the image , but you can see in the four images it moves across the frame. So what is it? Asteroid maybe? At first I thought it must just be something on the lens , but then after I saw the images on the computer you can clearly see it moves across the frame. And it wouldn't be a satellite (pretty sure anyway) because it would just be a line across the whole frame and just in one image instead of all four. Exposure times for the four images were 15.6s , 38s , 72s and 125.3s respectively and the ISO was set to 400. *** <center>☯</center> ***  *** So this is the camera with the normal 18mm-55mm lens with the 42mm camera projection eyepiece on the end of that. This does add a bit of weight to the setup , which is not really that good because I am pretty much running things at limits already with the 250mm Newtonian on the mount. The NEQ6 can handle 20kgs of payload , but they recommend only 18kgs for astrophotography. *** <center>☯</center> ***  *** This is what I normally use. Just the camera , a T-ring and a 2" attachment so it can be fit into a 2" focuser. With that setup the telescope is being used as the lens. *** <center>☯</center> ***  *** This is the hand controller , with the LCD display next to it , which is the part that decided to bite the dust. So the controller still works , I just can't see anything I'm doing which is essentially not usable :( . I bought the mount used and it's worked pretty good so far , however the LCD display on the controller has always been a bit dodgy. *** <center>☯</center> ***  *** The display is pretty easy to get to. Just four screws to remove the back cover and then two more at the top of the controller(the right side in the image) that hold the back light in. I'm not sure if you can see in the image , but the LCD display has a ribbon cable attached to it , that you can just basically unplug from the circuit board. You would think with it being somewhat modular that it would be a readily available replacement part right? But no , too easy hahah. The only thing I have found after a search was an old post on an astronomy forum wondering the same thing as me , where to get a replacement. So no luck there. However , the local electronics store has some LCD displays for sale with the same 14 pin input (I'm assuming they are all pretty similar anyway) , so i guess that will be my next project , to see if I can actually fix this thing. I did think at first that the universe is trying to tell me something , as in , to start controlling the mount with a computer rather than the hand controller , which is where I would like to get to eventually anyway. Thanks for taking the time to check out this post :)

Man this is so cool. I also want to photograph stars and galaxies one day. I did capture milky way once(and that too not so great) and thats been it. Great post:).

Cool , thanks for checking my post out :) . I actually started taking photos with a point and shoot camera , it wasn't the greatest , but it was pretty cool when that's all I was using. There will always be better equipment out there no matter what level you are at , so might as well get started with what ever you have. But one thing i would suggest starting out is to definitely have a tripod of some sort , and take a 30 sec shot of the sky and before you know it you'll get some pretty good results with that :) In saying that though , to be able to photograph galaxies you are going to need a telescope and something to track the sky. And with the telescope , the bigger the lens or mirror the better , you need as much light-gathering power you can get :)

Ok - the galaxy shot was insane. I can't imagine getting that myself. It blew my mind when I first saw Saturn, but a galaxy.. that is other level stuff. Also, it makes the most sense that it was a satellite that was moving across.. If you were seeing something cosmic moving that far, it would be travelling pretty damn fast!! Like probably faster than light.

Yeah that was pretty cool seeing that. I had tried previously to get some galaxy shots , but with no luck , so it was pretty nice to be able to actually see something this time :) . Anyway , yeah i also thought it must have been a satellite at first , but then i realized at the magnification i was at , it would have passed through the frame in less than a second. Sometimes you can see the satellites passing up there on a good night , just with your eyes i mean , and they are moving pretty fast , which made me think the object in the frames must be further out , in the solar system anyway , which is why i thought an asteroid maybe ... but who knows, could have been anything really. And hey , thanks again for checking out the post and leaving a comment :)

I see those satellites all the time when taking pictures of the dark sky, sometimes more than one pass by in a long exposure. Its really is amazing how much man made stuff we have floating around in space!
