Meade DSI Pro on an Orion StarBlast (imaging version), Meade DSI on a second Orion StarBlast (original version)
Description
This image of M20 was taken with a DSI Pro (L:59x30sec) at the prime focus of an Orion StarBlast (imaging version) and a DSI (RGB:19x60sec) at the prime focus of second StarBlast (original version) mounted side-by-side on a Meade 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.
