Twin homebuilt 35mm f/4 cameras, Meade DSI and DSI Pro driven by an LXD75
This wide field image of M51 was taken using a DSI Pro (L:50x30sec) and a DSI (RGB:20x60sec) fitted with twin 35mm f/4 achromats (the objectives from a 7x35 binocular) driven by an LXD75. The source images were saved as FITS3P combined offline in drizzle. Drizzle was also used to convert the FITS3P from the DSI to a BMP. The LRGB was then assembled in Photoshop.
