Mike Harlow took this image of Gyulbudaghian's Nebula using the 510mm F/4.5 scope at "iTelescope.net" in New Mexico. Gyulbudaghian's Nebula is a little-known variable reflection nebula, similar to Hubble's variable nebula. This nebula changes brightness and shape over many months or years. In years past it has been a challenge for an 18-inch scope under dark skies, but this month Gyulbudaghian's Nebula is much brighter, making this the perfect time to try to detect it in smaller instruments. Armen Gyulbudaghian is an Armenian astronomer at Byurakan Observatory. He discovered this nebula in 1977, apparently during a survey for new Herbig-Haro objects. At the heart of the Herbig-Haro object lies the variable Herbig AbBe pre-main sequence star PV Cep. This is a newly formed star that is surrounded by a rotating disk of material. At right angles to this disk are two jets of material, streaming away from the star at high speeds. We see the effects of one of these jets on the north side of PV Cep as the stream of material meets the surrounding gas in the interstellar medium. The jet to the south is obscured by a dark nebula (producing an absorption of over 3 magnitudes).
