When I was looking for M26, I chanced to look at a conspicuous but faint globular cluster like object in the constellation of Scutum. When I went back to software and verified, I found out that I had accidentally found NGC6712, a 8.1 mag globular in Scutum. A pair of conspicuous stars neighbours the globular.

I reobserved NGC 6712, a globular cluster in a rich area of the Milky Way near the planetary nebula IC 1295, because of the recent interest in this object on sci.astro.amateur. I first used a Cave 12.5" f/6.5 Newtonian reflector and at 65x (32mm U.O. Konig-II) the NGC 6712 appeared as a nebulous patch. Using my 19mm Panoptic (109x) did not resolve the globular. At 159x (13mm T.V. Ploessl) the cluster was somewhat resolved and had an irregular oval shape. About 45 minutes later I used a 17" f/15 classical Cassegrain at 202x (32mm Koing-II) and 341x (19 mm Panoptic) to view NGC 6712. At 341x I could see a distinctly elliptical shape and a hint of the dark lane on the southeast edge that the Webb Society's book on globular clusters mentions. NGC 6712 is a fairly large class 9 Herschel 400 globular of around 9th magnitude. I also located 2 new Herschel globulars that night, namely NGC 6144 near Antares and NGC 6426 northwest of Gamma Ophiuchi. NGC 6426 was particularly faint, being just at the limit of visibility with averted vision.
