How to Shoot the Moon

We’re often asked here at Bintel what the best way to take photos through a telescope is. In reality, half of our store is dedicated to selling not optics, but astronomical cameras, mounts, adapters, filters, and other accessories, so it’s not like there’s a “one size fits all” response. That said, for a beginner buying their first telescope, it’s not particularly hard to take a few shots of the brightest target in the night sky, and this quick guide will show you how, with two easy methods!

1: Use your phone – no additional parts required!

In the same way you position your eye above the telescope eyepiece to view the night sky, you can also position the camera on your phone. With a bit of practice, it’s not too difficult to line up the small pinprick of light to the camera sensor, allowing you to take photos of the moon with ease! Holding the setup still however is a challenge for everybody. Keep at it, and with persistence, you may end up with some very nice shots – the moon image above was taken with an iPad by one of our customers, Paul Woodhouse, and his Celestron CPC. This method will work for all telescopes, and can be used to take zoomed in images during the day too!

If you are struggling to hold your phone steady enough to take an image, it may be worth considering a smartphone mount, which will clip your phone directly to the eyepiece. Mounts similar to this are also available for point-and-shoot fixed lens cameras – see our camera adapters page for more.

2: Use your DSLR (for refractors and SCT cassegrains only)

If you have a DSLR camera with removable lens, taking the next step is an obvious choice to take excellent images. Depending on the brand of your camera, and the type of telescope you have, a few extra parts will be needed as follows, but once you get started, the exciting world of astro-imaging awaits! While this article is specifically about moon photography, this sort of setup will allow the dedicated astronomer to image planets, and some of the brighter deep space objects too, especially if the telescope being used is electronic with GoTo. For the best results, use a remote shutter for your DSLR to avoid unnecessary vibration, available at most good camera stores.

Part One: T-ring for your camera – this will allow your camera to clip onto the back of your telescope just like it would attach to a lens.

Part Two: Projection Camera Adapter – if you have a refractor, you will likely need this adapter to reach focus (in some instances, the t-ring may work directly on the telescope, but this varies between models). The included extension tube however is a welcome addition to any photographer’s kit, and will allow you to increase the magnification of your images, zooming right in on the moon’s craters!

Part Three: SCT Adapter – this replaces the visual back of an SCT (Cassegrain) telescope, and allows the T-ring to screw on. If you have a Nexstar 4SE, you will need the Mak Adapter

Now, you’re ready to get started!

Potential pitfalls to take note of:

  • DSLR cameras will more often than not fail to reach focus when connected to reflector or dobsonian telescopes, due to the optical arrangement of these systems. For the best results, we recommend only attempting this type of photography with glass-based refractors (of appropriate size) or schmit-cassegrain telescopes, however with the correct t-ring, some reflectors will be able to image (eg: the Skywatcher Collapsible GoTo Dobsonian range)
  • You may have heard of “long exposure astrophotography”, whereby the exposure of a camera is left open for up to half an hour, letting in as much light as possible to create the image. This requires an electronic tracking telescope, but it must be on an EQ-style mount. Most GoTo computerised telescopes we sell are on AZ-style mounts, and must be upgraded with a wedge for this more advanced form of photography. Without a wedge, these telescopes are excellent for short-exposure photos of the moon and planets, and are capable of imaging the brightest deep sky targets, but for the best results, a wedge is recommended. 
  • Please be aware that while any camera can be connected to any telescope with the right parts, mounting a big heavy DSLR on the back of a small refractor or reflector model is always going to cause stability issues, so taking a worthwhile image can be very challenging with this method. 

If you are unsure, please feel free to contact our full-time staff in-store for more details, or advice on how to set up your specific telescope and camera combination for astrophotography.

  • Just a comment – with considerable difficulty/trial and error, I was able to take a manually tracked photo (without star trails) of the Trifid Nebula for 10 seconds with a Fuji XM-1 mirror-less camera and T-ring adapter, with a f9 100mm APO refractor, just by rotating the horizontal slow-motion control very slowly. What was apparent was that if there existed a manual EQ mount for refractors, with a very good geared slow-motion control and adjustable reference rotating dial, one could take quite good quick relatively instant deep-sky photos this way – APO refractors do seem to do brighter deep sky imaging very well. Someone once made a gadget from Meccano that had 5 brass worm gears at different angles and five 19-teeth pinions, one rotation of the shaft was very smooth yet equaled a ratio of 19 to power 5 = 2,476,099 gearing ratio – which for 1 rotation in 24 hours would be gearing of about 28.658 rotations per second- the possibility seems to exist of error-distribution technology where one could manually rotate the system or use a motor for easy quick deepsky photos.

  • Hi Alan,

    Glad to hear of your success! Your logic is indeed correct, and with some very simple parts and procedures, it is possible to take passable images of deep sky objects with the setups described above (though of course as you mentioned, usually after considerable difficulty). Some mounts can be upgraded with a simple EQ motor to automate such tracking (eg: we sell the Orion EQ-3M Dual-Axis Electronic Drive in our store for this exact purpose), however at this point in time this and associated products are not up on this website, and we ask that people call us for inquiries so that we can establish whether the product is suitable for their purposes.

    Cheers,
    The Bintel Team

BIG Telescopes are on the way. Here’s some of them.

We’ve all be stunned by the images sent back by the James Webb Space Telescope (JWST) – but what’s happening on the ground? First of all, let’s look at why astronomers go through such enormous effort to put telescopes into space. The complexities of designing a telescope to work in space, launching it into orbit…

JWST Image releases: What’s next?

The James Webb Space Telescope – JWST – is now fully operational and has released its first science images this week that grabbed the world’s attention. With the JWST now “Open for business”, the world’s best astronomers are lining up to use this powerful new instrument.  To use the JWST you must go through a…

Astrophotography – Starlight meets the computer

According to the American Astronomical Society, the  charged couple device or CCD   was born on 17 October 1969 at Bell Labs in Murray Hill, New Jersey during a brain storming session between Willard Boyle and George Smith.  While it was originally intended as a solid state storage device, the imaging possibilities quickly became obvious. (Boyle…

Spotting Scopes and Binoculars – what’s the difference?

Most people are familiar with binoculars.  You might have even used a pair at the footy or cricket,  to watch  some of our wonderful native Australian birds and wildlife or even stare up the  night sky.
