It's slowly coming together as I throw $$$$$$$ at it .
M42,
SONY SLT A77V through Astronomik CLS filter and 80mmf5 Achro
13 ARW subs, 30Sec @ ISO 1000 converted to TIFF and stacked in DSS. (DSS won't handle the SONY ARW format natively.
No darks, no flats, nothing. (Very low noise sensor IMHO)
Processed in Paint Shop Pro for curves and brightness contrast. Cropped from full image, slightly sharpened and converted to jpeg.
Transparency not the best, high fine haze and 95% moon on east horizon. Love the CLS filter.
