Steve's Notes
=====
NGC 6235
18" (7/24/06): at 435x this globular was quite scraggly with a small, irregularly shaped core surrounded by a much fainter low surface brightness halo extending to 3'-3.5' diameter. At least 15 to 20 stars are resolved with 3 or 4 fairly easy brighter stars but most are very faint, in the mag 15-16 range. With extended viewing, several extremely faint stars pop in and out of visibility in the halo increasing the overall total to 25-30 stars, though a lower number were visible simultaneously.
17.5" (6/8/91): fairly bright, small, 3' diameter, mottled. A few stars are resolved at the edges of the halo including a fairly prominent mag 14 star at the east edge of the halo and another mag 14 star at the west edge of the core. The remaining resolved stars are mag 15 or fainter. The core is elongated N-S. The globular has an irregular scraggly halo due to unresolved star lanes. Located within a triangle of three mag 12-13 stars.
