I`ll try that, next time. It seems to me I`m getting some pretty poor seeing nights. It may be due to the high summer temperatures during the day & night (here in Australia). Last night I looked at the thermometer & it was still 90 degrees F at 11.15 pm at night!

ETX-125 f/15. I got the focus just right. Conditions were pretty
steady at 2am; steady enough to use every frame in the

points, so I used eight in this image, which kept everything sharp
except Copernicus at the edge. The primary reason I use Registax
is that I have a pc at work while the macbook pro is at home. I'm on
the pc all day, so it is convenient.

If you want advice, use the whole chip and just concentrate on focus.
