Description:
This extremely tiny planetary is located in a relatively heavy environment, it's not an easy find. At 71x you can perhaps suspect that it's something other than a simple star, I can hardly say that it has any extent. At 167x it looks like a little fuzzy star. At 300x the body of the planetary can be detected easily, as an object which is getting constantly brighter towards its centre. To the South a spectacular binary can be found the STF 2016 (a Struve double). The size of the planetary is about 0.5' and is perfectly round.
