OBJECT DESCRIPTION AND IMAGE SESSION

This is the faintest object I have imaged so far. A very dim planetary nebula located in the Constellation of Aquila. The object was selected because its diameter and I believe it is not visible with regular telescopes. At least no trace of the PN while shooting RGB. Not much information nor pictures of this object. Nevertheless it was interesting to see the capabilities of the SXV H9 under urban skies.

PK designations stands for Czechoslovakian astronomers Perek & Kohoutek  who publish a catalog of Planetary Nebulas in 1967

The picture was taken in bin 2x2 to get more light and then re sampled to 1392 x 1040 pixeles for processing. Finally the JPG file was reduced a bit for aesthetical purposes.
