Answering for Glen, yes, Centaurus A is the bright blob above Omega.
To help inspire you, last night I was doing an astro viewing night at a high school. Had everything going against me: thin cloud across the entire sky, dew, and terrible light pollution that was heightened by the thin cloud, and a first quarter Moon.
But, despite all this, just by star hoping through an 8X50 finder, I was able to nail Centaurus A on a C8 with a GSTAR camera coupled to it. Just by using the finder! Did the Sombrero next in the same way too,
. Both were totally invisible through the finder,
Mental.
