Jul 13, 2020 AstroSurface: software for images and video processing - posted in Astronomy Software & Computers: Hello, A few years ago i started programming functions for astronomical image processing. Since two years i share a software that works for Windows: AstroSurface. It is still in evolution, the actual version is: AstroSurface LEDA. There is a new version every month or so You can.
The line is becoming blurred between DSLR and Mirrorless digital cameras such as those by Sony, Nikon and Canon, and CMOS sensors used in dedicated astronomical cameras such as those by ZWO and QHY.
There are many different types of software that may help you astrophotography:
- Camera Control
- Software-Assisted Focusing
- Image Acquisition Automation
- Plate Solving
- Image Calibration, Aligning and Stacking
- Image Correction and Enhancement
- Autoguiding Software
- Photo Utilities
- Photoshop Filters and Actions
- Tutorials on Image Processing of Astrophotos
- Planetarium Programs and Atlases
DSLR Camera Control
With camera control software, you can use your computer to control all of the functions and settings of your camera, such as setting the ISO, opening the shutter, and shooting multiple frames for stacking.
With the current generation of Canon EOS DSLR cameras software by the camera manufacturer will control all functions of the camera. This is accomplished through a single USB-2 Cable and includes control of the bulb setting for exposures longer than 30 seconds. This software also allows viewing of the Live-view real-time image on the computer and focusing.
With previous camera generations of Canon DSLRs and Nikon DSLR cameras, the camera manufacturer's software could control all camera functions except one critical one for astrophotography: the ability to shoot exposures longer than 30 seconds with the bulb setting. This major drawback necessitated the use of third-party software to control the camera and access bulb exposures longer than 30 seconds through the use of a serial to bulb port cable. For old cameras, two cables were necessary for astrophotography: one USB cable to control camera functions and one serial to bulb port cable for long exposures.
Software-Assisted Focusing
The latest generation cameras allow focusing through the camera manufacturer's software. This can be done by manual focusing and visual inspection of the Live-view image on the computer, or by autofocus if the camera is shooting through an autofocus lens.
For previous generation cameras without Live-View, an image had to be downloaded to the computer and then visually examined for focus accuracy. Programs will download an image and then examine a star and give a readout of the star's diameter or brightness. This metric-assisted focusing is objective and did not rely on any visual interpretation to determine focus.
Through a process of manual trial and error, accurate focus could be achieved through software-assisted focusing.
The latest DSLR camera manufacturer's software can make focusing very easy with Live-view, and some, like BackYardEOS, BackYardNIKON and AstroPhotography Tool use metric-assisted focusing for astrophotography.
If you have a mototized focuser, you can use software-assisted focusing to autofocus your telescope.
Image Acquisition Automation
Serious deep-sky astrophotography requires shooting many short exposures. This can be done manually, but it is very tedious. For example, faint deep-sky objects may require several hours worth of 5 minute exposures that are later stacked or combined in subsequent image processing.
Software such as Images Plus or MaxDSLR can automate this process. You simply specify in the software that you want the camera to shoot, say, 25 exposures of 5 minutes each at ISO 1600 with a pause of 10 seconds between frames (to give the system time to download each image).
The latest software provided by Nikon and Canon also provides the functionality for this type of automated image acquisition with the latest generation of DSLR cameras.
Plate Solving
There are several free pieces of software that will take an image (a short exposure) and 'plate solve' it for you. That means it examines patterns of stars in the image to determine the exact center of the field of view of your camera and scope. Once this is determined, the software can send these coordinates to your mount so the mount knows exactly where it is pointing to improve accuracy of GoTo's.
Plate solving is also useful if you shoot the same object over several nights. You can then solve an image from the first night, and store it. Then the next time out, you can just use that solve to frame your object for that night.
Image Calibration, Aligning and Stacking
Advanced astronomical imaging requires the 'calibration' of the raw original images. Calibration means removing unwanted fixed signals (such as thermal current and bias), and correction for signal modifications (such as vignetting) so that the raw image accurately represents the intensity of light incident on the sensor during the exposure. We will discuss these topics in detail in future sections, but right now lets just talk briefly about the software required for image calibration.
Both Canon and Nikon usually include image processing software with their cameras, but this software is for processing normal daytime images. You can not use it for image calibration, aligning, or stacking at all.
To calibrate your original raw astronomical images, you will require some type of special astronomical image processing software, such as Images Plus, MaxDSLR, AIP (Astronomical Image Processing), AstroArt, IRIS, Deepsky Stacker or Regim.
'Stacking' means combining many individual short exposures into a master image by any of several mathematical processes such as averaging, or addition. The term originates in the days of film astrophotography where images were literally stacked on top of one another to improve contrast and color.
You will also need to align your images so that the stars in them line up perfectly.
Whatever software you use for image calibration will almost certainly also do aligning and image stacking. It is possible to align and stack images in Photoshop, but for more than a couple of frames, the process is extremely tedious and not as accurate as with a dedicated astronomical image processing program.
Image Correction and Enhancement
Once your images are calibrated, aligned and stacked, you will want to correct for things such as color balance, and increase the contrast to make faint details more visible. You will probably also want to apply some type of noise reduction, and you may want to apply more sophisticated enhancement techniques.
These processes can be done in the previously mentioned astronomical image processing programs such as Images Plus, MaxDSLR, AIP (Astronomical Image Processing), AstroArt, and IRIS.
However, at this stage of image processing, many astrophotographers prefer to switch to a general image processing program such as Photoshop.
Autoguiding Software
For long-exposure deep-sky astrophotography, guiding during the exposure can be very useful in producing higher quality images. By manually or automatically following a star by making corrections in right ascension and declination higher tracking accuracy is obtained.
Autoguiding involves using a separate CCD or Webcam to monitor a stars position and then send corrections to the telescope's mounting to guide or follow the star with high accuracy to compensate for inaccuracies in the mount's tracking.
SBIG used to make the ST-4 and ST-V which were stand alone autoguiders which did not require a computer. These units have been discontinued but can be found used on Astromart.
Embroidery software for pfaff sewing machines. Tru Embroidery available as is a full package and comes with Dongle.
CCD cameras and webcams can be also be used as autoguiders, but software, such as GuideDog and PHD, is required to run on a computer that interfaces between the autoguider and mount.
Photo Utilities
These programs perform useful functions like allowing you to open FITS format files, perform noise reduction, and create thumbnails for indexing and archiving.
Photoshop Filters and Actions
These filters and actions work inside of Photoshop and perform specialty functions for astronomy, such as gradient and noise reduction.
Tutorials on Image Processing of Astrophotos
Tutorials in book and video format teach you how to do astrophotography, and use programs such as Images Plus for image calibration and Photoshop for image correction and enhancement.
