Hi Kevin, Everyone seems to think that raw is better, so I thought that
I'd better see for myself; apparently you do lose some fine detail in JPEG.
Regarding ISO 6400, I actually use anything between 1600 and 6400,
depending upon how well I've polar aligned on the night. At my age
humping my HEQ5 Go To and 8" newt in and out is becoming a bit
burdensome, not to mention all the other bits and pieces that one needs.
So, sometimes I only align with a compass, and therefore have to keep
the exposures short. Neatimage does a pretty good job of reducing the
resultant noise. Incidentally, I've never been able to find anything that
tells me how to upload images to IIS; although ,I don't know how to
downsize my images to a size suitable for uploading anyway. As you can
tell, I'm not exactly comp literate. I sorely miss the relative simplicity
of my film days. Although highly skilled digital imagers can produce
amazing pics, I feel that reality has left the hobby, and artistic
interpretation has taken over. For example, the other week there was
a row of about 5 images of 253 in this forum from various imagers, and
they were 5 distinctly different colours. It seems that some imagers
produce results that they find aesthetically pleasing, rather than the
colour that the object actually is.
