    (I'm new to photography )
    Darks refers to Dark Frames. A method of noise elimination. Basically you take a photograph with your lens/telescope cap on for the same length of time as your Light exposure. It's recommended you take 80-100% Dark Frames as your Light Frames. So if you take 200 Lights that's what 180-200 Darks also.

    Since I image with my little Meade DSI I take a series of dark frames for each time exposure setting. This is usually in the range of 1-30 seconds. I do this using the Meade Envisage program. Dark frames are used to remove noise from your light frames (your images). Since I stack my images using DeepSkyStacker, I add my light frames and my dark frames. As DSS states, "With light frames containing a lot of hot pixels it is highly recommended to check dark frames in order to avoid false star detection which may highly perturb the alignment."

    Thanks very interesting reading and so helpful. It sure give you a good feel for what is needed to accomplish astrophotography with Azimuth mount. I can say that even knowing how much work goes into creating good photos that it will be worth the effort. Thanks again I'm looking forward to the learning experience.

    The SkyWatcher SynScan AZ GOTO mount is very good for azimuth mount photography; however, you need to tighten up the tripod a bit. Tighten all the nuts and bolts, especially the bolts that hold the upper tripod leg sockets to the tripod head. Inject super glue in the extremely tiny crack between the upper tripod legs and its upper and lower tripod leg sockets being careful not to get glue on any moving parts. Always have the accessory tray installed and locked in place. Don't extend the extension legs. This will make the tripod suitable for photography.

    The 127MAK is a bit slow for azimuth photography. You can add a focal reducer and improve the situation but it still will be around f/8.. which is on the slow side for 15 to 30 second exposures. For about the same amount of money a focal reducer and adapter brackets will cost you can buy a SkyWatcher StarTravel 80 short tube f/5 refractor which will make an excellent telescope for photography and a great wide field of view telescope to go with your 127 MAK.

    You have a camera, telescope, and mount..... get a t ring for your camera and an universal 1.25inch t ring adapter .... then go out at night and start shooting. Wont take you too long to get going... Use your camera's live view and a bright star to focus.

    Thanks so much for all the details. I got my first scope and a DSLR, lots of parts and pieces to connect all and now I have a guiding light to help me see a path to some success.

    Welcome to the Astronomy Forum. Why not drop by our introductions forum and introduce yourself. Only takes a minute or two. BTW, what telescope do you have?

    Thanks for the welcome, I have just gotten the Nexstar 8 GPS (carbon fiber tube), and have gathered a nice assortment of eyepieces,etc. I have also snagged a Rebel XS. Is yours modified? I see you list a Nexus7 and was wondering if it has apps for the camera? I have just done a basic collimation of the scope, skies here (east Texas) have been hazy and humidity is killing me, lol.

    About the only thing I still want is a focal reducer, and am trying to decide between a 2" screw on or the SCT threaded one. I use the 2" SCT quartz dielectric diagonal from highpoint and am not sure I want to keep swapping out parts.
