afesan Posted August 14, 2013 Report Share Posted August 14, 2013 On August 17th, 2010.. this telegram was sent by the bulgarian astronomer Mr. E. Semkov (from Sofia Institute of Astronomy), reporting a new possible FU Orionis star into the vicinity of NGC 7000 Gulf area. http://www.astronome....org/?read=2801This is V2493 (HBC 722).Now.. 3 years later ( August 2013) the little ourbust of a star can be seen clearly as a nice gold-yellow nebula... emerging into the Gulf area. Most images of this area are taken in narrowband filters and nebula is not seen.. This was taken in LRGB pure...If you search images before August 2010 you did not find any nebula After August 2010..you can see nebula size is increasing year after year. Also of interest in the upper left corner there is another star with a little white relection nebula . This is V1057 Cygni.. reported in 1969..but many astrophotographers did not repair on it.You can read more into these links:http://www.aanda.org.../aa15902-10.pdfhttp://arxiv.org/pdf/1306.0666.pdfThe Blue reflection area at the upper right corner is coming from the light of the blue star SAO 50180 (spectral type B5V) just out the field of the sensor...You can see the full image at: http://afesan.es/Deepspace/Also Annotated image of objects at: http://afesan.es/Anotada/ Best regardsAntonio Link to comment Share on other sites More sharing options...
