Cluster images

Hi,

I'm looking for somewhere on the net that has images of star clusters
taken at different times (maybe every 5-10 years). I intend to look at
stellar motion within clusters, so the images would have to be of
fairly high resolution.

Failing that, are there any easily accessible robotic telescopes
online?

Just a quick reply to this from me....

Have a look on Google for "UK Schmidt Plates" and "ESO Schmidt Plates".
I think you might find something useful in these.

Failing that, have a look at Aladin
(http://aladin.u-strasbg.fr/aladin.gml). You can specify an object in
this and retrieve loads of different types of observations (at various
epochs).

Cheers,
John Tanner

Not only clusters Conor. I recall one of my University practicals was
to determine the date of the Crab Nebula explosion by determining the
expansion rate of the object by comparing images taken at widely
spaced time intervals.
