Why Digital Astrophotography Is Better than Analog

Digital astrophotography involves photographing astronomical objects in the sky, and many beginners are interested in trying their hand at this. But, it’s often hard to figure out whether or not you should choose analog or digital photography to take these pictures. Here is a brief overview of both to help you figure out which is the best.

Analog

Analog photography involves using different mediums like film and a CCD sensor to capture images. While this form of photography has its proponents, it’s actually quite difficult to get clear images using this type of photography.

It’s hard to focus on the object in the sky, and the exposure can be dull. It can wash out the colors that of the object that you have been painstakingly photographing. Plus, you have to wait a really long time to see what the final image looks like. It takes at least 30 minutes to get results and oftentimes even longer.

Digital

While it may seem counterintuitive since digital cameras are everywhere, digital cameras work quite well for astrophotography. You can obtain a cheap digital camera, buy an afocal adapter, and then just put the two together. And, now you have a fully functioning digital astrophotography camera.

Digital cameras take better pictures since you can adjust the exposure to brighten the image and reduce graininess. Plus, you see your pictures immediately so there’s no waiting between shoots.

The major downsides to digital cameras are that the extra eye piece could cause vignetting (a reduction in either brightness or saturation). And, there’s also the problem of them being really heavy, which could cause the mount to be less accurate.

Digital vs. Analog

Despite its problems, digital cameras just take better pictures than analog. You should just always take pictures in RAW mode since this will allow you to further process the image. JPEG images are harder to manipulate due to the compression.
