First test of full disk image available using Point Grey Grasshopper Express 6MP camera on
AP155EDF refractor. To get a full disk, an AP 0.79x reducer was used, resulting in an
effective focal length of 931mm, and an image scale of 1 arcsec/pixel. Coronado SolarMaxII
90mm, single stacked, BF30. Firecapture, Autostakkert!2, Registax 6, Photoshop CS6.
