Cent A - Old favorite and an old version vs now.
Thought I would go back to an object I have not imaged since moving on from my 20d/VC200L. Here are the images, new (ST2000, GSO RC10cf) and old, to be fair the old shot was using the Vixen Sphinx mount and I had guiding issues at the time that limited the subs to 2 mins whereas the L frames now are 16 mins. If I had that same kit now I think the results would be better....but I think the mono CCD makes a huge difference and the G11 makes guiding a breeze.
