This is the first stage of an M31 mosaic project I have undertaken this summer. This image is a four frame mosaic, where each frame currently contains 39 minutes of luminance data collected over two nights. I started the project a bit early, so M31 was probably too low in the sky and the background gradient is quite prominent in the raw data. This is a complication for processing but also means some of the data is overwhelmed by background. I plan to repeat the luminance data later in the summer when M31 is higher in the sky.
