White nights is almost here. Currently there is less than two hours of complete darkness, and it will be worse. At my northern latitude I need to wait till the end of July for better conditions. But before autumn has come (even before actual summer has began) I pointed telescope low above eastern horizon to catch some Milky Way treasures in Cygnus. The Moon is almost full, so I decided to use hydrogen alpha narrowband filter and aimed my setup to centre of IC1318 emission nebula next to Sadr. It is also called Butterfly Nebula or Gamma Cygni nebula. IC1318 is quite extent and with my narrowfield setup I was able to capture only its small fragment. I reviewed my old image of IC1318 and selected this region with several dark nebulae:
Image was made at my backyard observatory with Meade ACF10″ telescope and QHY163M camera on EQ6 mount. It is total 5 hours of exposures made through hydrogen alpha narrowband filter. The dark nebula right off the centre is TGU H469 P2 from Tokyo Gakugei University catalogue.
IC1318 nebula itself is a part of larger hydrogen cloud in Cygnus that spans at distance 2500-5000 light years away from us and it is located in Orion Arm of our Milky Way.
