    Another Astrophoto...M33 Triangulum Galaxy
    Enjoying my new astrophotography hobby very much. Here is M33 the Triangulum Galaxy.

    This consisted of 18 x 6 minute exposures.

    My current setup looks like this

    Another Astrophoto...M33 Triangulum Galaxy-astrosetup-1-1-.jpg

    This is more or less an entry level setup. I have a Celestron Advanced VX mount with a 6" Newtonian type telescope.

    The mount itself is the most important part of the rig. This is needed to find and track the objects in the sky. The tripod will rival most if not all high end tripods for photography use. The tripod is made of 2" stainless steel legs. Incredibly sturdy. Not exactly something you would want to carry around though. lol

    The mount is computer controlled via the handset you see in the picture. Through the handset is where you tell your mount where you are and inputting time and date. Also this where you do your star alignments. When everything is completed, you just tell the mount what object you want to see and it will point to that object and track it.

    The big tube is the main telescope and what I use for imaging with. It is a simple Newtonian. No lenses or any kind of glass is used the optical train. Light goes through the opening and reflects of a mirror at the other end of the tube. Bounces the light to a secondary mirror which then reflects the light into the focuser. This is where my Nikon camera gets attached.

    The smaller telescope on top is part of my autoguider. Unless you are a perfect human being, this is unnecessary. But nobody is perfect. Meaning when you do your initial setup, it requires a polar alignment. This being a german equitorial mount, this is key to making this type of mount to work properly. So when properly polar aligned, the mount only moves on a single axis versus two axis on an altaz type of mount commonly used in photography. Even with a decent polar alignment, most mounts will have tracking errors. So the second telescope is smaller and has a small camera attached to it. One cable goes to the computer and the other gets plugged into the mount. So you point your telescope at an object in the sky. The small telescope and camera gets aligned to a star in the field of view. Then with a program that I run on the laptop, it can more accurately fix the minor tracking errors leaving no star trails. Keeping the image nice and sharp with no apparent movements even though the telescope is moving the entire time keeping up with the earth rotation. This allows for extremely long exposures. Without which, your exposure times will be significantly reduced. With tracking AltAz mounts, even good ones, your exposures will be limited to about 30 seconds. With a EQ mount like this and with a decent polar alignment, I have been able to increase exposure times to about 2 minutes. With the autoguider, sky is the limit depending on how well the polar alignment is.

    I hope some of this makes sense. I am a beginner to say the least at this but I am having fun with it.

    Perfectly good explanation.
    I am thinking of attaching my camera to my 8 inch dob. I am not ready for buying all the gear to do tracking, but I would like to buy the attachment for the focuser.

    Who did you go through to buy your gear?

    Re: Another Astrophoto...M33 Triangulum Galaxy

    An awesome shot, and great set up, thanks for posting! I used to have a Celestron SLT130 telescope, great fun for relatively little money. Work & family meant I didn't get chance to use is as much as I used to, so I sold it however I know that one day, I will buy another 'scope.
    Once you have tried looking through a telescope, you will spend every clear night after that just stood staring at the sky.

    Re: Another Astrophoto...M33 Triangulum Galaxy

    I bought my gear through various vendors, ebay and AstroMart.

    An 8" dob is a great telescope for visual use. But terrible for astrophotography. No way to track but by hand. So you will be extremely limited in exposures. A second or less. Also I don't know if there is enough back focus on the dob to allow you to focus with a DSLR. You might have to add a barlow in the optical train to achieve focus.

    But what you can do with the dob is use a planetary camera like a Celestron NexImage 5 (which I have) or just modify a webcam and video capture the planet as it moves across the FOV. Then run the video through a program called Registax 6 and it will stack the individual frames of the video into a photo. You should be able to get stunning results with planets like the Moon, Jupiter and Saturn. You can also try the DSLR for video if your camera supports it. But the wide field of view using a DSLR will make the planet look pretty small.

    So just get a t-ring and an adapter to fit your dob and you should be good to go.
