Finder map for NGC 7027

Best viewed from the Northern Hemisphere where it reaches high altitude. Very low and difficult from most of the Southern Hemisphere. Its extremely small angular size makes it appear stellar at low magnifications. High magnification is required to resolve its non-stellar shape. The central star is very difficult to observe visually.

Observation Notes

Naked Eye

Not visible.

Binoculars

Not visible as a nebula; at best appears as a faint, stellar point even in large binoculars under very dark skies.

Small Telescope

In 4–6 inch apertures, appears at low power as a bright, stellar-looking object. The blinking technique is useful to distinguish it from field stars, with or without a narrowband filter. At higher magnification (around 150× or more), a tiny, non-stellar disk may occasionally be suspected under good seeing.

Medium Telescope

With 8–12 inches at high magnification (200× or more), the nebula resolves into a very small, high–surface-brightness disk with a slightly elongated or boxy outline. A blue-green coloration is often noticeable.

Large Telescope

In apertures of roughly 14 inches and larger, the compact, rectangular appearance is clearly defined with direct vision. The central star remains an extreme visual challenge, glimpsed only during moments of excellent seeing, while an O-III filter markedly enhances contrast and helps the nebula stand out against the background.
