Astrophotography Telescope. You may wish to start snapping images of what you observe through your telescope at some point. There are several methods to achieve this, some simpler than others. Whatever you do, you’ll need some form of camera.

Best Telescope Cameras: Digital or Film?
Best telescope cameras, In general, film is superior to digital for astrophotography. Long exposures (greater than about 30s) are currently not permitted in digital camera technology because the heat generated causes interference and disrupts the components (I believe I’ve seen it done with some kind of cooling mechanism, but that is far beyond my experience, and the scope of this article!) The film can be allowed to absorb light for hours, making it ideal for astrophotography in low-light conditions. this is one of the best Best telescope cameras.
Best telescope cameras. That is not to imply, however, that digital cameras have no role in the field of astronomical photography. The use of a digital camera makes photographing brighter subjects much simpler than with film; in fact, digital cameras are better suited for beginners than film cameras are, given the significant benefit of Best telescope cameras being able to view the captured image almost immediately after it has been captured by the camera. Since this, you will be able to master the process much more quickly because you will not need to wait for your film to be returned from the lab in order to determine what works and what does not work. In all likelihood, a novice will only have access to the afocal approach while using a digital camera. This method involves merely with your Best telescope cameras bringing the camera up to the eyepiece and shooting the photo at that point. However, even with this approach, you may get fantastic results; things like the Moon and Planets, as well as some of the brighter clusters that are more difficult to photograph, work well with digital cameras.
Best telescope cameras exposures may, however, be done with film, including star trails and piggyback photography, both of which can provide outstanding images even for inexperienced photographers.
For the primary focus and eyepiece projection techniques, an SLR with a detachable lens may also be mounted directly to the camera.
Best Telescope Cameras: Digital
- The more ‘pixels’ there are, the better. To approximate the image, a digital picture is composed of millions of different-color pixels (picture parts). The more pixels your camera has, the sharper your picture will be. Remember, the more pixels you have, the larger the file size, and therefore the fewer photographs you can save on a given memory amount.
- Check that it allows you to adjust the shutter speed. Because the camera was not meant to function in the low light conditions of astrophotography, it will be unable to appropriately set its own settings. You must manually adjust the shutter speed.
- Most should have it, but check to see whether it has a ‘timer’ feature. Often, pressing the button to snap a photo is difficult because you will vibrate the camera and destroy the image. A timer allows you to hit the button and then steady the camera in preparation for the photo.
- Zoom is useful. Don’t be deceived if the advertisement claims tremendous zoom capabilities; this is digital zoom, which severely degrades picture quality (all it does is crop the image and magnify the remaining part, meaning that fewer pixels are being used and therefore reduce the quality). Optical zoom is a “true” zoom that has no influence on picture quality. This is normally up to half the claimed digital zoom, but it may occasionally have none at all, so double-check.
- Battery life: Digital cameras are notorious power hogs, quickly depleting a pair of batteries. It’s especially aggravating when you’ve just set up the ideal photo and the batteries abruptly expire.
- Because of the vibrations, holding the camera in your hand becomes hard for more ambitious images, such as planets or close-ups of individual lunar craters. A tripod or similar support is recommended here. Scopetronix (and I’m sure there are others if you check around) provides a nice small gadget that directly connects your digital camera to the scope, allowing you to avoid touching the camera and, if your scope has an auto-guider, allowing you to keep the item in view. You may be able to test longer exposures of 15-30 seconds depending on their accuracy. It’s worth contemplating if you intend on performing a lot of digital camera photography.
Please keep in mind that I’m talking about telescope cameras regular digital cameras, not CCDs, which are particularly intended for telescopes and fit into your eyepiece. I would not advocate this for beginners; instead, start with much easier approaches before spending a lot of money. If you need more information about them, Al Kelly’s CCD website is excellent.
Best Telescope Cameras: SLR
For most astrophotography, you need an SLR camera. SLR is an abbreviation for single-lens reflex cameras. It offers three significant benefits over other kinds of cameras:
- What you see via the viewfinder is what will be focused on the film—you are seeing through the lens. Other cameras have a viewfinder immediately above the lens that you look through. This is required if you want to connect your camera to a telescope in any manner.
- Most SLR cameras have replaceable lenses, which means they may be mounted to a telescope and use the optics of the scope instead of a lens.
- They provide you with complete creative control over the photo and allow for extended exposure.
SLR cameras come in a variety of shapes and sizes, ranging from current all-singing, all-dancing versions to 1970’s mechanical cameras. There are many of these available, and older ones can typically be had at a reasonable price. For astrophotography, you don’t need much from your camera; in fact, the fewer functions it has, the better. The issue with contemporary cameras is that they feature an electronic shutter, which rapidly drains the batteries. I have one of these (I got it for regular photography as well) and you definitely pay for it in batteries, with just approximately 2-3 hours of exposure (ordinarily this would take hundreds of thousands of photos, with hour-long exposures in astrophotography they go very quickly.) So, if you’re searching for one right now, acquire an old, mechanical one; they’re less expensive and will save you a lot of money on batteries.
What you need from your SLR:
- Purchase an older mechanical one!
- They should all work, but make sure you can adjust the shutter speed manually and that it has a ‘B’ or ‘BULB’ option.
- Check to see whether a cable release is available for it; you’ll need one for most astrophotography.
- If you want to connect it to your telescope in any manner, ensure sure a T-ring is accessible. It’s not the end of the world if there isn’t, since there are workarounds, such as universal camera adapters, but it does make life easier.
That’s all really, you don’t even need a meter since these don’t function in such low light anyhow. In fact, it’s worth hunting for nice cameras with defective meters that are being sold at a discount.
Best Telescope Cameras: Accessories
Another advantage of SLR cameras is the availability of hundreds of accessories. Some camera accessories are almost indispensable:
- Release by cable. This means you don’t have to touch the camera to capture the photo, and you may use lengthy exposures by locking the shutter open. If you have an electronic SLR, this will be an electrical wire, and you will need to find the correct one for your model (and spend a lot on it!). If you have a mechanical one, it will most likely attach to the release button. I believe they are all quite convenient and can be purchased from any photography store.
- T-ring. A T-ring attaches to the lens fitting on your camera and has a standard thread on the other side to suit any telescope adapter that connects to your eyepiece holder (there are many telescope adapters, but they all fit all T-rings and most eyepiece holders). There are many different kinds of fittings, but the two most common are bayonet (align up and twist like a light bulb) and screw-fit (screw in like, well, a screw!). You must choose the correct one for your camera’s fit. If you’re unsure, take it to a camera store and they’ll tell you. Typically, you can purchase a t-ring for your camera’s manufacturer that will suit the majority of their cameras (as an example here’s one for Minolta cameras). If your camera does not have a T-ring, there are still methods to attach it to a telescope; there are universal camera adapters available (see Scopetronix)
- Tripod. Keeps the camera stationary and allows it to be pointed in any direction. Useful.
