Bright planetary with several details. Darker center breaks the nebula down into two lobes (NGC 650 & NGC 651). Western lobe is irregular and brighter than eastern one. Eastern lobe is roundish and more blur than western one. 292x and UHC-filter shows faint overhangs that curves from the lobes. Looks like a spiral galaxy which has a weird core.
