Planetary Nebula Observations

by Hilary Jones


Except as noted, these are the photographs of Planetary Nebulae that I submitted to the Astronomical League's Planetary Nebula Program.

I used a PlaneWave CDK 12.5" telescope on a Paramount MX mount, which is located in my suburban observatory in Northern California at latitude 37° 49' N, longitude 121° 59' W, and altitude 109m. I took all the pictures using an SBIG ST-10XME camera and Astrodon filters. Except as noted, six images were acquired for each filter using an exposure time of 300 seconds per image. I used CCD Commander to drive the process, and TheSkyX to control the scope and camera. I did the post processing using MaxIm DL, CCDStack2, and Photoshop CS4.

I photographed all targets using two filters. The first filter was an L filter, which appears in the image that usually shows on this web page. But if you hover your mouse over that image, a different image will be displayed to show how the object looks with the second filter. This was either an OIII or an Ha filter. The contrast of the two pictures has been adjusted to make them roughly the same everywhere except near the planetary nebula itself. In some cases you may need blink the two images to identify where the nebula actually is.

You will see that many of my pictures were taken with an Ha filter, where you might have expected the OIII filter to be the better choice. However in my experience many targets were barely visible with the OIII filter, while they showed well with the Ha filter. I assume that this was because my Ha filter was better able to suppress sky glow.

In the following tables, the seeing is given by the full width at half maximum (FWHM) of a typical star's profile, expressed in arc seconds; and the sky darkness is expressed in magnitudes per square arc second (mag/sq"). Both values were measured directly from the image, so they differ from what would have been measured at the zenith. I did not use a Sky Quality Meter to obtain the sky darkness, although that data is available upon request.

To see a list of the Planetary Nebulae that were photographed for this project, click here. I tried to stick to the official target list for the Astronomical League's Planetary Nebula project. But my observatory doesn't allow me to photograph objects at very low declination, so I had to supplement the list with objects from Abell's Planetary Nebula catalog.

Image of Abell 16Notes: Barely visible disk. I spent a lot of time comparing my picture to photos on the web before I could positively say that the shape in my picture was correct. This picture really should be redone with more exposures; and it would probably show up better using an Ha filter.

Image of Abell 21Notes: Very large irregular structure, rather like looking into the end of a cylinder. Oriented NW/SE,with heaviest end in the SE, and the dimmer "open" end of the cylinder in the NW. Many streams of material cross the area. Many stars, so it's not obvous which one was the original cental star, if any. Can be seen faintly in L picture, but Ha is much better.

Image of Abell 71Notes: A flat but slightly mottled disk shape, with two arms suggestive of a spiral galaxy. It has been said that this target is not actually a planetary nebula because it has almost no OIII emission. Instead it might just be a cloud of H gases. This object is embedded in a nebulous cloud of material known as SH 2-115, details of which can be seen in my photograph.

Image of Abell 74Notes: This target is quite large, occupying almost the entire frame; and it is quite dim, almost nvisible. It is basically a flat disk with slightly heavier areas to the S, W and E. The image is quite noisy, and it would take a much longer exposure time to see any structure. I have checked this image against others to confirm that I am seeing real structure and not just artifacts.

Image of EGB 6Notes: Extremely faint ring shape. This target required a great deal of post-processing to reveal even the slightest hint of a nebula. I have compared it to other pictures on the web, most notably at http://astro.neutral.org/imagehtml/20120225-egb6.html; so there is no doubt that the photograph is correct. The ring is heaviest in the SW, but does continue full circle if one looks closely. Many stars in the area, so it's not obvious which if any is the central star. This image was done with only a half-hour total exposure time. It needs to be redone with several hours to make a truly convincing case.

Image of Jones 1Notes: Large fairly uniform disk, but with heavier parts on the NNW and SSE. These areas seem somewhat indented from the rest of the expansion front, so perhaps the material was slowed down. There is also one heavier area to the S and outside the main disk. This could be an artifact or the debris from an earlier expansion.

Image of NGC 2371Notes: Appears roiughly circular in the L picture, with strong features to the NE and SW. The nebula has been described as "double lobed", and the L picture does barely show the two outer lobes. But these show up more more prominently in the OIII picture as two arcs to the NW and SE. The central star is especially prominent in the L picture.

Image of NGC 6543Notes: Large irregular ring that has been broken up into many pieces. Gives the impression of a flower. To the W is a particularly heavy area that lies closer to the center than the rest of the ring. This area can be seen in the L picture too. Farther out and slightly to the S is a "swoosh" shape, perhaps a case where the expanding debris encountered a pillar of creation. There is an extremely bright area in the center, with an irregular shape, suggesting that the planetary nebula has undergone more than one explosive event.

Image of NGC 6853Notes: Dumbell Nebula shows up well in both L and Ha picture. Because of clouds, the L picture was only 5 minutes, and the Ha picture totalled only 15 minutes. Nonetheless structure is visible everywhere in this large target, including some wispy features outside the main body. A central star can be seen in the L picture. There is a lot of mottling in the Ha picture, but not so evident in the L picture.

Image of NGC 6879Notes: Almost stellar. The object is said to span 4.7 arcsec, but it measures 6.8 arcsec due to very poor seeing. Neighboring stars measure just slightly less (6.4 arcsec), so this might be taken as evidence that the object is not stellar. The target's brightness also differs between the L and Ha images, which can be taken as evidence that this is not a common star.

Image of NGC 6884Notes: The only way to know that this isn't a common star is to compare the L and Ha images. Also the nebula's FWHM might be a little bigger than for neighboring stars, suggesting that I might have been able to see a little structure if seeing had been better. Note that there is also one feature in the SE corner of the image that brightens slightly in the Ha image; so this might be another Planetary Nebula. The L and Ha exposures totalled just five seconds each because the session had to be terminated when the sun was rising.

Image of Pease 1Notes: This is a tiny planetary nebula embedded in the M15 cluster. It is located at about 11 o'clock, and about half way out from the center of the nebula. Its size is only 1 arcsecond, so there is no way to resolve any structure. The only way to know that this isn't a common star is to compare the L and Ha images, and even then the target barely jumps out from the cluster's stars.

Image of Sh 1-89Notes: Butterfly shaped, with long thin "body" oriented NW/SE, and circular "wings" on the sides. The wings extend out a little farther than the length of the body; but there are traces of nebulosity even farther out, particularly to the SW. There is one bright star at the SE tail of the body, but it seems more likely to be a foreground star than a central star. No other star would qualify as a central star. The wings are quite noisy. It would take a much longer exposure to show these areas off well.

Image of Simeiz 22Notes: A large crescent Moon shape, with many striations. The loop is heaviest in the SE and completely disappears in the NW. The crescent is visible in the L picture, but is best in the Ha picture. There are several stars near the center of the nebula, any of which could be the original star.

Image of Vy 1-1Notes: Stellar. The only way to know that this isn't a common star is to compare the L and Ha images. Also the target is slightly larger (6.4") than the surrounding stars ("4.7"). It is reported to have a size of 14"; but this doesn't seem to be supported by my image. However seeing was poor, so perhaps it would have shown up better on a better night or with a different filter.

Image of Vy 2-2Notes: The FWHM of the target is very close to that for the stars. Perhaps with better seeing one woiuld have seen a difference; but with the given data the only way to know that this isn't a common star is to compare the object's brightness in the L and Ha images.
