The 'Western Veil' or Witches Broom Nebula is part of the Cygnus Loop, other parts of the loop include , the 'Eatern Veil' (Caldwell 33), and Pickering's Triangular Wisp. It is part of a large, relatively faint supernova remnant in the constellation Cygnus. The source supernova exploded some 5,000 to 8,000 years ago, and the remnants have since expanded to cover an area of ~3x3 degrees. The distance to the nebula is not precisely known, with estimates ranging from 1,400 to 2,600 light-years.

The analysis of the emissions from the nebula indicate the presence of oxygen, sulfur, and hydrogen.
The nebula is notorious among astronomers for being difficult to see visually, even though it has a bright integrated magnitude of 7. However, a telescope using an OIII filter (a filter isolating the wavelength of light from doubly ionized oxygen), will allow an observer to see the nebula clearly, as almost all light from this nebula is emitted at this wavelength. Using an 8-inch (200 mm) telescope equipped with an OIII filter, one could easily see the delicate lacework apparent in photographs. With an OIII filter, almost any telescope could conceivably see this nebula, and some argue that it can be seen without any optical aid, excepting an OIII filter held up to the eye. This is also one of the largest, brightest features in the x-ray sky.

C23 is an edge on unbarred spiral galaxy about 30 million light-years away in the constellation Andromeda. It was discovered by William Herschel on October 6 1784. The galaxy is a member of the NGC 1023 group of galaxies in the Local Supercluster. It has a H II nucleus.

Visually, the object is visible in small to moderate size telescopes as a faint elongated smear of light with a dust lane visible in apertures 200mm and above.

C22 is a fairly popular planetary nebula for casual observers.

A small refractor will reveal a star-like object with slight nebulosity. A 6 in. telescope with a magnification around 100x will reveal a slightly bluish disk. Telescopes of diameter 16" or greater may reveal slight colour and brightness variations in the interior.

The North America Nebula covers an area of more than four times the size of the full moon, but its surface brightness is low so normally it cannot be seen with the unaided eye.

Binoculars and telescopes with large fields of view (approximately 3°) will show it as a foggy patch of light under sufficiently dark skies.

However, using a UHC filter which filters out some unwanted wavelengths of light, it can be seen by the naked eye under dark skies. Its prominent shape and especially its reddish colour (from the hydrogen Hα emission line) only show up in photographs of the area.

Image by Leigh Slomer NGC 7000, Sharpless 117, Caldwell 20 The North America Nebula. An emission nebula located close to Deneb in the constellation of Cygnus. My 1st serious attempt at an astro image. Taken from images captured over 3 nights in late September and early October, it was my 1st image to go more than a few minutes over 1 hour in total exposure time and the 1st to incorporate proper calibration frames.

C15 is a planetary nebula located in the constellation Cygnus. It is commonly referred to as the "blinking planetary", although many other nebulae can exhibit such "blinking".

When viewed through a small telescope, the brightness of the central star overwhelms the eye when viewed directly, obscuring the surrounding nebula. However, it can be viewed well in the peripheral vision (averted vision), which causes it to "blink" in and out of view as the observer's eye wanders.

A distinctive feature of this nebula are the two bright patches on either side, which are known as FLIERs.
