Omega Centauri (NGC 5139) is the largest and brightest globular cluster seen from Earth.
This is a minimal expo image, I took only one image per filter.  Despite the short integration time, the brightness of the object allowed to get a decent picture. Here is a widefield image of the same object took in 2010 with the same scope but DSLR camera.
