Thanks Raymo, good to know...
How do you think it would go on galaxies such as M83 & the like...
The image scale looks better than say with my 80mm or 5" newt but, I have no idea about imaging galaxies & how it might or might not shape up in a long focal length Mak..
I understand that imaging will require longer exposures Vs my much faster refractor or Newt..
Cheers
