Astrophotography with the Nexstar SLT 102

Images processed with GIMP and/or DSS.

All taken with an 102mm F6.5 Celestron Nexstar refractor and Canon 1000D DSLR at prime focus.
Most are taken with the telescope mounted on the HEQ5 mount, but those marked 'SLT' were taken using the original alt-az mount.

Each object is shown either 4x4 binned ( ~8''/pixel) or 2x2 binned (~4''/pixel), both cropped to 600x400. Occasionally the full frame (3888x2592) is scaled to 600x400.
