The beauty of exoplanet transits is that they can be observed with amateur equipment and doesn’t require that you have access to a professional telescope located at a prime observing site. To be able to succeed at observing a transit you do need to know what you are doing. Here I will very briefly mention things to keep in mind.

Equipment needed

First off, good data analysis skills are very important and should not be underestimated. If you don’t know what you are doing and why, it won’t really matter how good your equipment is. To be able to observe exoplanet transits you will need a telescope which is able to track the sky accurately. An auto guiding system is essential. The greater the aperture of the telescope the greater signal to noise you will get and the easier you will detect the exoplanet. An 8 inch telescope will be able to detect exoplanets orbiting a star of magnitude 10 or less. With a 12 inch most transiting exoplanets will be available for observing.

Detector needed

Any 16 bit CCD camera should do the job. Dark current for instance is not so important as the exposures taken are about 30 seconds long.

Targets

The transiting exoplanets which you will be able to observe will depend on the size of the telescope you have. I would recommend to start of with the brightest objects such as HD 209458 or HD 189733.

Software

Once you have the data there are a number of ways which you can reduce the images. Examples are IRAF and MaxIm
