In short - yes.

It is really a dark site object or CCD object from the suburbs preferably with an Ha filter.

Here is a Canon 20D shot from my dark site a few years ago its about 90 minutes or so from memory and ISO 3200:

Here is a 10 hour image from the same site with an Sbig STL11 camera and LRGB plus Ha:

It is a dim object with not many guide stars nearby also.
