Steve's Notes

===== NGC 7305 24" (12/1/16): at 260x; fairly faint, fairly small, roundish, ~24" diameter, small bright core, diffuse halo. A mag 15.7 star is 40" N of center. The blazar CTA 102, located 5.6' ENE, was near the maximum of a historic outburst. It appeared marginally brighter than a mag 12.9 star on the AAVSO chart, so perhaps mag 12.7 or 12.8. This is 4.5 magnitudes brighter than its normal quiescent state. At z = 1.037, the light-travel time is ~8 billion years. This is certainly the most distant object in recorded times to be visible in a 6" scope. 17.5" (8/20/88): very faint, very small, round, small bright core. A mag 15 star is 30" N. Located between two stars mag 13.5 1.6' NW and 2.1' E.
