Description: I used a 13 mm Baader Hyperion which gave 280x with a 15 arc-minute field. M27 fills the whole field with this combination and the view is unbelievable! The familiar dumbbell-shape is gone and the major axis has been turned 90 degrees compared the view of small telescope. Central area is very bright and it's difficult to detach faint structures inside the glow. O-III filter is the right aid for this object. Everything becomes much sharper. It's almost impossible to sketch all small details which are in view with the averted vision. The coolest details are in the ''wings'', that contain several fibrous structures.

Description: A hurried sketch of Dumbbel Nebula at 16'' Meade LX 200 GPS on the wet paper. I think the awful sketch tells everything...

Description: M27:ää on lähes mahdotonta kuvata sanoilla, kohde täytyy nähdä itse kaukoputkella. Piirrokseen on mahdoton vangita sen loistoa. Katsoin kohdetta 244 -kertaisella suurennuksella Celestronin LPR -suotimen kera. M27 täyttää melkein koko näkökentän. Tuttu nostopainon muoto oli helposti havaittavissa. Eteläisen puntin läntinen osa on selvästi sumun kirkkain osa. Toinen selvästi muuta sumua kirkkaampi alue on pohjoisen puntin koilliskulmalla. Keskustähden alueella sumu on selvästi himmeämpi kuin punteissa. Keskustähti näkyikin todella helposti. Suotimen ansiosta sumun himmeimmätkin osat tulivat syrjäsilmällä näkyviin. Punttien päistä lähtevät varret koskettivat toisiaan sumun kummallakin puolella, mikä teki sumusta lähes täydellisen ellipsin. Sumun sisällä näkyi keskustähden lisäksi monia muitakin tähtiä.
