The nebula will require very dark skies to see without a filter, particularly with telescopes smaller than 16 inches. It appears as a round hazy patch that is very faint. This one is a challenge for an eight-inch scope.
Sixteen-inch or larger scopes will show sharp edges and a slightly darker central region.

In my 18-inch without a filter it was a very challenging object, appearing as a very slight round haze with averted vision. I had to observe this one on different nights and spend a great deal of time to convince myself that I really did see it.
The above image from the DSS using SkyView shows a 20' x 20' field about the nebula. North is down and east is to the right.
The above color image was created by combining red and blue second-generation DSS images. Note the apparent faint distant galaxies within the bounds of the nebula!Millennium Star Atlas Vol III Chart 1181 Sky Atlas 2000 Chart 8 Uranometria 2000 Vol I Chart 156
