I think it's probably safe to say that one man's data may not necessarily
equate to that of another's.
To construct an astro image - whether for aesthetic or scientific purposes,
using today's tools and technology - one definitely collects data. In the
modern world, binary information, no matter if it's used for finishing touches
on "Angry Birds" or following the maturation process of Supernovae, is data.
The M81/82 pair has got to be the best in the sky (from Earth's point of view).
Nice composition, Darren. I've been known to fuss about artistic license in
astrophotography once or twice, but I still like pretty pictures.

Hi Darren,
While a nice image, there is no data.
Other than identifying a SN the data would photometric and a light curve of its
progress. And/or you could do low-resolution spectroscopy of the SN over time
and help classify it and see changes. Both these techniques can be done wiht a
modest telescope. You would need a monochrome camera, however.
Taking pretty pictures can be fun and rewarding, but very little science can be
gleaned from the images. If you really want to produce something of value
"data." look into spectroscopy or photometry.
