Got Your mail as a forward from a Swedish amateur astronomer, Timo Karhula. Mr. Riku Henriksson and I observed a quasar with a redshift of 3.41 about 1 1/2 years ago. This QSO called Q0014+813 is (IIRC) in northern Draco and might be somewhat more difficult from more southern sites. Still, it is not too tough as the magnitude is 16.2 which is very bright for such a distant object. Q0014+813 is/was actually the brightest known (constant-luminosity) single object in the universe. I don't know if this record has been broken. Our visual observation was made with a 25-inch (630mm) dobsonian (ala Obsession) with a magnification of about 300x. This turned out to bee a bit of an overkill as the QSO was readily visible without averted vision even if the condition were far from perfect (setting moon, some auroral glow etc.). I think it must be visible with much smaller scopes. Clear skies and happy hunting =09Jere Kahanp=E4=E4 =09jere.kahanpaa@helsinki.fi PS. As I don't know the mailing list address in the original forward I didn't send this to the lis. You can, if You think it is appropriate, forward this mail to the list.
