It is 2.5° wide.  The maximum field of your scope is around a degree.

Maybe 1.3° with the reducer.

Wrong target for the scope.

Excellent in an 80-100mm short focal length refractor, photographically.

The Heart nebula is a quite large object, at something like 1.5 degrees in extent. Your best bet is to point at the sparse cluster at its <ahem> heart ;) , where some of the brighter parts of the nebulosity lies. Big stuff like this benefits from a smaller telescope which can provide an FoV of more like 2 degrees. Why, a 50mm finder would be better here than a C-8 with focal reducer.

Gentlemen,

                   Thanks for your input.  I'll just cross this off my list until I obtain the proper scope.  There are plenty of  breathtaking objects out  for me.

You need a wide field... my 80mm jumbo finder and NV shows it well with space around it, good for the other big nebs in the area.
