M57
Ring Nebula in Lyra


10.1'' reflector  115 x
 
Could never find this one in the 2.4" scope, but found it easily with the 10.1" at lowest power beside Beta Lyrae. Appears slightly oval-shaped, brightest along its outer edges and darkest in the middle. Looks somewhat like a smoke ring. At low power (43x) it looks very much like a dim planet. Apparent size is a little under 2' across.

Beautiful wide field image containing M57 at center. Multiple colours from blue to red are visible.

Zoomed-in view of the previous image. Edges on the east and west sides appear to bleed into the background with subtle undulations and seem to be partially transparent. Pretty much the entire spectrum of colours from red to blue can be seen from the outer to inner portions of the ring. The central white dwarf star is clearly visible in the middle, along with another star to the upper-right and some cloudy knots. Another star is visible to the lower right near the edge of the ring, presumably in the foreground.
