ARO 11 Anyone?
Hello fellow observers!
I had a gander in Cygnus last night wandering the rich starfields in this northern constellation with my 10 inch dob. I can only go as far north as Sadr (Gamma Cygni) as the rest of the constellation is occulted by my neighbours roof.
I enjoyed looking at Albireo, beautiful colour contrast gold and blue. Some lovely starfields as you sweep down to Sadr. I located the planetary nebula ARO 11, also know as Campbell's Hydrogen Star for the first time last night. Gosh what a beaut! It looks stellar at 70x, starts becoming fuzzy at 133x and reveals its true nature at 300x. What is special about this object is it's colour, a reddish coppery colour. Nice! I boosted the magnification to 686x and saw some vague structure. It still looked a faint red even at this magnification.
I'm interested in hearing about your observations of this interesting planetary. Have you seen it before? Cheers.
Clear Skies
Joe
