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 Add On supports Canon camera drivers.Canon DSLR driver for Mac included with Mac Daily Build installer (OS X 10.6 or later and Intel Mac required). See TheSkyX Pro and SAE User Guide Revision 1.4.3 or later for details about using this driver. Tweaked Polar Alignment report to make it more understandable.
The Trius Pro 694 bundle has something for everyone, while generally a deep-sky camera, it can be used for imaging the Sun and Moon as well. The camera is Windows and Mac compatible and the included Starlight Live software allows you to stack images live as you capture them. Read our full Starlight Xpress Trius Pro 694 review.

This 1st beta has comet registration.
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.

Hugely sensitive, really fast frame rates under USB3.0, IR sensitivity on all pixels longer than 810nm - this is a lovely camera. The read noise being low and sensitivity being high means short exposure stacking for DSOs works fairly well - and allows lucky imaging techniques to bring out.detail. that would not normally be there.

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. https://bvmfveu.weebly.com/blog/best-mac-optimization-apps.

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.

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, A
