Equipment
DSI Pro II behind homebuilt 6" f1.8 astrograph & 10" LX200R @ f 3.3 H-alpha, green and blue filters used (no lums)
Description
In this 4 frame mosaic I tried to highlight the faint H-alpha wisps that surround the M42,43 and NGC1977 nebulas. 20+ x 2min subs were stacked using a full apature H-alpha filter with the fast astrograph to capture these frail smokish threads and the larger 10" scope was used for inner detail. Each was scaled ,layered together and ballanced fro color in PS.
