A star-like object with slight nebulosity can be seen in a small telescope. ngc 7662 is a popular planetary nebula for casual observers. Ngc 7662 is a popular planetary nebula for casual observers. NGC 7662 is a planetary nebula located in the constellation Andromeda.
NGC 7662 is a popular planetary nebula for casual observers. NGC 7662 (also known as the Blue Snowball Nebula, Snowball Nebula and Caldwell 2) is a planetary nebula located in the constellation Andromeda. Wikipedia This image is part of the Hubble Gallery of Planetary Nebulae. NGC 7662 is estimated to be between 2,000 and 4,000 light years away and therefore has a spatial diameter between 0.35 and 0.70 light years.
How big is the Blue Snowball Nebula?
Although faint as seen from Earth (its apparent brightness is 8, ), the Blue Snowball is actually a huge cloud of expanding gas almost a light-year across. Although it appears small in the sky and has about the same visual latitude as Jupiter, it is one of the few deep-sky objects that shows colour when viewed through telescopes of modest size, earning it its popular name. Caldwell 22 or ngc 7662 is a planetary nebula located between 1,800 and 5,600 light years away.

Can nebulae be seen with a telescope?
No telescope makes distributed objects like NEBULS, GALAXIES and (most) PLANETS appear brighter than they can be seen with the naked eye. A trench of dusty material at the base of the fish mouth separates M42 from a fainter nebula to the north. To see the more distant and fainter objects such as galaxies and other nebulae, you may need a telescope with a larger mirror. To the south of the belt hangs the Sword of Orion, which consists of three bright points; the middle point is the Great Nebula.
I think my article clearly explains why you can’t really expect to see fabulous coloured nebulae without a camera.
