RE: [APML] FSQ-106 - my early results...

Hello Jeff,
Those are very nice first results.  As Michael suggested, stacking and
using a highlight mask will help the M42.  I have been told that the
Epson 4870 or flatbed scanners in general are very good at reducing
grain of print negative scans.  Did you scan the negatives or the
prints?  Thanks for sharing.

Best regards,
Jeff Ball

Here's some of my first film results with the FSQ...

M42...

This is on RG400, 20 minutes or so, on the G11 guided by a ST7E.

The scanning was done by a epson 4870, which had its
"first light" last night.

B33 (old PPF400)...

Another M42...

gamma cygni (also old PPF400)

(not as good as nicola's)

These are all single exposures.. Stacking would
help.  Thats next.

In some images, the prints looked good, but scanning
at 4800dpi showed stars a bit oblong near the edge -- the
polar alignment was off.  The FSQ is rather forgiving
with its 530mm focal length, so I thought.
