Usually we shoot multiple images and align and stack them to improve the signal-to-noise ratio in the images. Once you have shot your images, you will need to process them to make them look their best. Simply click on an object in your planetarium program and tell the mount to point the scope at it. Planetarium programs will allow you to control and point your Go To mount. You'll also be able to see your images at a larger size on your computer screen compared to the LCD on the back of the camera.

You can use software metrics to help you focus as well as program in a series of long exposures and pauses between them. The price to be paid for this, however, is additional complexity, powering a laptop computer at the scope at a dark-sky remote observing location, dealing with USB connection issues, and cable routing.Ĭamera control software will allow almost complete control of the camera while you sit at the laptop computer. Dithering is changing the scope pointing a small amount between exposures to help deal with noise and hot pixels in the images. Once you get a little more advanced, using a laptop at the scope can make pointing and camera control a little bit easier and also allow more advanced techniques such autoguiding, and dithering. I didn't even have a Go To mount, I just used setting circles and star charts. I shot without a computer at the telescope for 20 years back in the days of film before digital cameras. You can focus with Live View, and then take test exposures to determine the correct exposure and framing of the object you want to shoot. When you first start out it is much easier to skip the computer. Perform any post-processing you wish, including editing these adjustments.You don't really need a computer and software at the telescope to shoot astrophotos.
Upon leaving the Astrophotography Stack Persona, each image in the Stacked Images panel is added as a new pixel layer near the bottom of the document's layer stack.Ĭurves and Levels adjustments, with settings calculated during the stacking process, are added at the top of the layer stack.
Browse to the corresponding frames, select them, then select Open.(Optional but recommended) For each set of calibration frames that you have shot:.Browse to your light frames, select them, then select Open.On the Files panel, set Type to Light frames, then select Add Files.Select File>New Astrophotography Stack.To open the Astrophotography Stack Persona: Bad Pixel Map Tool-automatically or manually identify defective pixels in specific kinds of calibration frame.Crop Tool-crop the document to remove unwanted areas.Zoom Tool- zoom in and out of the document.Hand Tool- move around the document by dragging on it.To rename a stacked image, double-click it on the panel.Įach stacked image becomes a pixel layer (of the same name) in the resulting Affinity Photo document. Use the Stacked Images panel to compare results from using different files and options. across several nights, during which shooting conditions may have changed. Multiple file groups can be added to the panel for processing into a single end result.Įach file group should contain frames taken at different times, i.e. It is recommended that you add calibration frames as well.Įach set of light frames and calibration frames constitutes a file group. Stacked Images-all images created during a single session in the Persona are added here.Īt minimum, a set of light frames must be added to the Files panel.RAW Options-choose how the frames are interpreted.Stacking Options-choose and control the stacking method used to process the frames.Files-specify the light frames and calibration frames to be processed.On the Tools panel, the Persona provides the Bad Pixel Map Tool, which helps to identify and correct defective pixels that originate in a camera setup. The Astrophotography Stack Persona's key controls are located in the right studio, where you can specify the files to be stacked and how they are processed.
