Taking a 'night time' or an Astrophoto doesn't require anything more than your camera and a steady tripod.

First choose a dark site away from any direct lights. A lens hood will prevent any stray light from spoiling your images, and to a degree, stop dew from forming on the lens. Various Filters can be used but are best left off.

Mount the camera on the tripod (a bean-bag will do) and change your camera's setting to Manual Exposure (M). This lets you decide the shutter speed and aperture of the camera.

Set your shutter speed to at least seven seconds (up to 30 seconds), and your aperture at the fastest lens setting (usually f/2.8 or f/3.5), and then set your ISO to 1600 (less in light polluted areas).

Manual Exposure
You can set both the shutter speed and aperture as desired.

1 Set the Mode Dial to Manual (M).
2 Set the shutter speed and aperture.
To set the shutter speed, turn the dial (near the shutter release).
To set the aperture, hold down the 'Av' button and turn the dial.
3 Set the exposure and take the picture.
The exposure level indicator in the viewfinder indicates the exposure level up to ±2 stops from the standard exposure index at the center. While you change the shutter speed and aperture, the exposure level mark will move. You can decide which exposure level to set.

If using a zoom lens, (as a first test), set it to its widest setting. Turn off the Autofocus (and set to Manual). Remember to Focus the camera lens on infinity.

Finally, set your JPEG compression settings to low compression and Higher quality (this will mean larger image file sizes). Shooting in (12-bit) RAW file format will be less noisy, but the EOS 1000d CMOS chip performs quite well at ISO 1600 especially if you turn on High ISO Speed Noise Reduction and Long-Exposure Noise Reduction (See manual). The camera resolution should be set to 3888 x 2592 pixels (10.1 effective megapixels); this will produce high quality JPEG ~3.8Mb and RAW ~9.8Mb image sizes.
Turn off the Built-in Flash and Red-Eye Reduction.

Canon EOS to T-thread (F) Adaptor

EOSRING4.jpg 

A Canon EOS T Ring allows you to connect your Canon Digital SLR Camera to a telescope, when coupled with the appropriate T-adaptor.   The T-ring simply replaces the lens on your camera.   The T-ring (Female M42 x 0.75 metric thread) simply attaches to the camera body in place of the camera lens, allowing the telescope to become the camera lens. This method of astro imaging is known as prime focus imaging. You can also place a Barlow lens before the T-adaptor to increase the magnification.

A bonus is that some (Skywatcher) Barlow lens have T-adaptor threads (the actual Barlow lens can also be removed).

 This T-Adapter with the M42 thread on top, allows you to connect the T-Ring so that you can mount your SLR camera to your telescope. Such a setup will allow lunar and planetary photography- and even deep-sky photography

Sky-Watcher 2in T-Mount Adaptor.

Designed for use in telescopes with 2" focusers.

 Simply: To use a T-Ring, remove the diagonal and/or eyepiece from your telescope. You now need only remove your normal camera lens, attach the proper T-Ring for your camera, and mount the combination to the rear cell of your telescope or spotting scope with a T-Adapter.

The EOS 1000D is compatible with the range of EF/EF-S lenses.

Tip: An adaptor will allow the use of Olympus OM lenses on Canon EOS cameras, (Other adaptors are available for other camera lens fittings). Olympus OM Zuiko Lens are of excellent quality and can be found in second-hand shops and online websites. It should be noted that although the lenses will fit physically, (with some adaptors), automatic diaphragm, auto-focusing, or any other functions will not operate correctly. In this case "stop-down mode" will need to be used when metering since the lens does not have the ability to have its aperture controlled by the camera body. You can shoot with manual mode or aperture priority mode with Canon EOS body. Some AF-Confirm adapters can emulate as a Canon EF auto-focus lens and have the electronics to communicate with the EOS camera.

Canon EOS 1000D is a 10.1-megapixel digital single-lens reflex camera announced by Canon on 10 June 2008 and started shipping in mid August of 2008. It is known as the EOS Kiss F in Japan and the EOS Rebel XS in the United States and Canada. The 1000D is an entry-level DSLR that has been described as being a step below the 450D.
The camera shares a few features with the 450D. It offers Live View shooting, DIGIC III Image Processor, and SDHC media storage. However, it has seven focus points (opposed to nine) and does not have spot light metering. The 1000D is also the second Canon EOS model (after the 450D) to exclusively use SD Card and SDHC memory storage instead of CompactFlash.

Price:£371.39


A 10.1 Megapixel CMOS sensor captures enough detail to make A4-size prints, even when cropping your image. Canon's CMOS sensor technology also ensures crisp, sharp images even in low-light conditions. ISO sensitivity 100-1600.

As a budget camera for astrophotography, the 1000D is a bit of a steal, capable of producing excellent astrophotos with very good noise handling even at high ISO settings.
