I am working with a small group of students at Hamline University on observing an exoplanet using transit photometry.
Right now, our group is working on buying equipment. The school already has Celestron C-8 telescopes with motorized mounts available for us to use, but we don't have a camera. We need a camera that we can use to take a long-exposure photograph of a single star, and it needs to be able to measure the brightness of the star very accurately.
Our budget is about $1,000, but the cheaper the better. So far, the only camera under $1,000 I have found that might work is the Atik Titan. One person I asked about this camera said that the anti-blooming technology might cause problems, and that the chip in the Atik Titan is too small. This person proposed the ST-402ME as a better model, but it costs $1,500.
Does anyone know either of these cameras would be sufficient for our project? Is it worth the extra money to buy the ST-402? Or do you have any other recommendations?
Many thanks in advance for any help!
