CCD image taken with a ST-6 CCD camera thru Kopernik’s 20 inch F/8 telescope. The exposure was 10 minutes. The field of view is approximately 5x7 arc minutes, with north at top.
NGC 6309 was discovered in the mid 19th Century by Tempel but it was first identified as a planetary nebula by Pickering in 1882. Our exposure is too short to show the very faint outer parts of the nebula.
