I think some of you have imaged this guy though. NGC 4236 is a galaxy spanning about 22 arc minutes in Draco. I suspect it is not frequently visited due to its low surface brightness. Its odd that it is dim yet relatively close (as part of the M81 group). I actually binned the luminance 2x2 in order to get reasonable signal level. The image and exposure / processing details are here:
