More 20D vs Starshoot
Here is the same region with the 20D, the image is 16*3 min shots through the 8 inch at f6.3 and reduced in size 50% and heavily compressed to get under the 150kb limit, full size jpg is 4mb, tiff is 48mb. Needed to be guided of course and you can see my alignment was not great - I got rotation.
Compare to the simplicity of acquiring 30x30s unguided with the OSS using the 66mm, then again I have much better detail in the 20D shot.
They are both good is my conclusion!
