BEST OBJECTS IN THE NEW GENERAL CATALOG by A.J. Crayon and Steve Coe version 1.0, dated Thu 01-04-1990 Questa lista è utilizzata dai membri del Saguaro Astronomy Club di Phoenix. I nomi delle costellazioni sono in formato IAU standard.
Le galassie sono identificate dalla loro catalogazione Hubble (Hubble type). Le dimensioni angolari sono espresse in arcominuti, salvo altra indicazione specifica. Per ogni oggetto c'è identificata la mia osservazione visuale e seguendo il link quella di Steve Coe fatta con un 13", la parte sottostante è tenuta integralmente dalla pagina originale del SAC.
Di seguito le osservazioni di Steve Coe con un 13" f/5.6, dove non indicato altrimenti. NGC 891 17.5"--Pretty bright, Pretty large, Very elongated, central bulge obvious, outer arms show sculptured detail at 200 X NGC 7662 17.5"--Pretty bright, Pretty small, Round greenish dot at 100X. 320X, central hole seen easily, central star suspected in good seeing NGC 6781
Bright, Large, somewhat elongated at 100X. It is immediately obvious without
the UHC filter. This planetary is shaped like the gibbous moon with the
south side brighter in an arc. There is one star involved that stands
out very nicely. The UHC filter helps some. I estimate its' size at one
arc minute. NGC 7293 Good in binoculars, 17.5"--Very large, Faint, annular, Central star easy at 100X. UHC helps a lot. NGC 772 17.5"--Pretty bright, gradually brighter middle, Pretty small at 150X NGC 1907 pretty bright, pretty small, much compressed and resolved at 165X. Just seen in 11X80 finder, I counted 22 stars in 13". NGC 1931 Bright, pretty large and somewhat elongated. Looks like a small comet at very low powers. There is a triple star in the center, it is resolved at 200X. NGC 1501 17.5"--Bright, Pretty large, Round Bluish disk at 165X, no * seen NGC 2403 17.5"-Pretty bright, Large, Somewhat elongated at 135X the spiral arms sparkle with mottling NGC 2655 Bright, pretty large and little elongated at 135X. This galaxy is much brighter in the middle with a bright central nucleus at 220X. NGC 185 Pretty faint, large, elongated 1.5x1, somewhat brighter middle, sonewhat mottled at 100X. NGC 281 Pretty bright, large, irregularly round, with 14 stars involved at 100X with the UHC filter. It is just seen without the UHC. A dark lane intrudes into the nebula on the south side, forming the Pac-man or Giant Comma shape. NGC 457
Bright, large, pretty rich, compressed. 63 stars counted including Phi
Cass, it is a light yellow star at the edge of the cluster at 100X. There
is another bright star near Phi that gives the effect of having two glowing
eyes looking back at the observer. In the Southwest we call this cluster
the Kachina Doll, two sparkling eyes and the rest of the cluster outlines
outstreched arms with feathers. Many tribes in the Southwest made NGC 663 Counted 69 stars at 100X. Bright, large, very rich, much compressed. Several 8th mag members across the face of the cluster. There is a curved north to south dark lane down the middle of the cluster. This is one of the best Non-Messier open clusters. It is unmistakeable in the 11X80 finder. NGC 7789
160 Stars estimated by counting 40 in the N to W quadrant. Bright, large,
very rich, very much compressed at 100X. NGC 5128 Very bright, Very large, little elongated, dark band, 17.5"-- Bright, Large, Round, Bright Middle, dark band easy at 100X, several * in foreground NGC 5139 Omega Centauri SRC-wowie zowie 17.5"--Very bright, very, very large, extremely rich, very compressed What can I say, the KING of the Globulars NGC 40bright,
large, and elongated 1.5X1. Central star obvious at 200X. The color is
grey at all powers. At 200X and above from one of our best locations,
the nebula shows off two brighter ends that look like "polar caps"
on Mars. The western cap is larger NGC 6939 Bright, large, rich, compressed and irregularly round in shape at 135X. I estimated 70 stars, there are lots of dimmer members. This cluster has many lovely chains of stars meandering out into the Milky Way. It is easy in the 11X80 finder. NGC 6946
This face-on spiral galaxy has a low surface brightness and therefore
responds to the atmosphere more than edge-on systems. For that reason
I have called this object "pretty faint" on a night I rated
5/10 and then called it "pretty bright" on a night that was
8/10 in the mountains of Northern Arizona. In any case it is pretty large,
somewhat elongated and has a bright, almost stellar nucleus. Even at the
best of times I have never NGC 7129 pretty faint, large, roundish nebula with 6 stars involved at 100X. The UHC filter does not seem to help. 7133 is nearby, it is faint, small and round with 2 pretty faint stars involved. NGC 246
is a very nice planetary to break up all these galaxies. NGC 936
Pretty bright, pretty large, round, much brighter middle. NGC 2359 Pretty bright, large, Irregular shape. Nebulosity extends out of the 30 minute field at 100X. UHC filter helps the contrast of this object a lot. I have always heard this object called the Duck Nebula because the shape includes a side view of a duck head with a bill. NGC 4274 bright, pretty large, much elongated, brighter middle at 100X. Has three companions in 40' field of 20mm Erfle. Brightest of three is 4278. NGC 4414 pretty bright, pretty large, elongated 3X1, much brighter middle at 100X. At 165X, stellar core comes and goes with the seeing. NGC 4494 bright, pretty large, round, much brighter middle at 100X NGC 4559 bright, large, much elongated 3X1, somewhat brighter middle at 135X. Three stars involved in south arm make this object unique, don't miss it. NGC 4565
very bright, very large, extremely elongated 10X1, very bright middle
at 135X. Dark lane is easy at a good site, it can be held with direct
vision. At 200X some fine detail within the dark lane is visible in moments
of good seeing at our best sites NGC 4725
bright, large, much elongated, very bright middle at 100X. My old 17.5"
would show a hint of barred spiral structure at 125X, but I have not had
the chance to use the 13" on this object from an excellant site to
see if the smaller scope will duplicate NGC 4361
Bright, large, elongated 1.5 X 1 in PA 90, somewhat brighter in the middle
at 100X. Central star is easy at 220X. NGC 4111
Bright, pretty large, much elongated (3X1) in PA 165. NGC 4214 Bright, pretty large, round, much, much brighter in the middle with a bright nucleus at 165X. The nucleus is elongated in PA 45. NGC 4244 Bright, large, very, very elongated in PA 45 with a gradually brighter middle at 165X. NGC 4449 Bright, pretty large, elongated 2 X 1 in PA 45 and a little brighter in the middle at 165X. There are several pretty bright stars involved in the mottled arms. NGC 4490 very bright, much elongated, gradually much brighter in the middle and it appears to touch 4485 in the same field at 150X. NGC 4631 very bright, very much elongated with a stellar nucleus at 150X. It has a very faint companion galaxy to the east. NGC 4656
pretty bright and large with a very irregular shape. NGC 5005
Bright, large, much elongated (4X1) in PA 60. NGC 5033 Bright, large, very much elongated (4X1) in PA 0 with a bright stellar nucleus at 165X. This is the most narrow galaxy I ever remember observing, it appears razor thin. NGC 6819
can just be seen in the 10X50 binocs. I counted 52 stars at 165X. Bright,
pretty large, much compressed, rich. NGC 6826
is the Blinking Planetary. This medium sized, 9th magnitude planetary
can be located at 100X. It appears as a non-stellar blob in the Milky
Way. I first saw the blinking effect in an 8" scope at 200X. If you
look directly at the planetary the central star is prominent compared
to the greenish nebulosity. Then averted vision will make the nebula appear
brighter and overwhelm the star. Alternating between direct and NGC 6960
and NGC 6992are the
brighter parts of the Veil Nebula. NGC 7000
is the North America Nebula. This large area of nebulosity needs an RFT
to be seen in its entirety. A dim glow can be seen in the area with the
naked eye and 10 X 50 binoculars at a dark site will show the North America
shape. NGC 7027 is an emission nebula that gets included with planetaries because it is only 5" in size, a resonable error. It seems bright, pretty small and somewhat elongated at 135X. The central star is seen occaisonally and it has a nice bluish color. NGC 5907 Bright, large, very much elongated, bright middle at 100X. At 200X the core is gradually brighter with a stellar nucleus. NGC 6503 Pretty bright, large, much elongated 3X1, somewhat brighter middle at 100X. NGC 6543
Bright, large, elongated 1.8 X 1. The central star can be seen at all
powers, but is stellar only on the best of nights. NGC 1232 17.5"--Pretty bright, round, bright middle, bright nucleus with arms a soft glow at 100X NGC 1535 17.5"-- Bright, Pretty large, Round, easy at 100X 2 rings, brighter central and dimmer outer annulus, central * in good seeing, light green at all powers NGC 2158 is a compact cluster near M35. It is pretty bright, pretty small, very compressed and just resolved at 100X. The cluster is better at 165X. It is very rich with an arrowhead shape. NGC 2392
is a bright, large and round planetary. It's central star is obvious at
all powers in the 13". At 200X, the star is encircled by two rings.
There are several dark marking within the rings. These markings make the
"face" that gave this object the NGC 6207 pretty bright, pretty large, elongated 2x1, somewhat brighter in the middle at 100X. NGC 6210
bright, pretty small, elongated, central star easy at 135X. Averted vision
makes this planetary grow in apparent size. NGC 3242 Wow, Looks like CBS eye, greenish at all powers, Central star easy at 300X. Very bright, large, round. AT 650X on a night I rated 8/10 for seeing, there is a small, dark circular area around the central star. A very nice planetary with lots of internal detail at high power. NGC 7209 Several nice chains faint *, orange * on one edge, not compressed NGC 7243 Not much, coarse group, triangular shape NGC 2903 is one of the best non-Messier galaxies. It is easy in 10x50 binocs or a large finder scope. At 175X in the 12.5" f/6 this galaxy is bright and is mottled across the face with a much brighter core. There is a bright spot about 4 arc minutes from the core. NGC 3384 is pretty faint, Large, somewhat elongated and does not have a brighter middle in the 12.5". NGC 3384 Bright, large, elongated 2.5 X 1 in PA 135 with a bright middle at 100X. Looks like a mini-Andromeda galaxy. NGC's 3605, 3607
and 3608form a tight group
in the 12.5" at 100X. NGC 3628 is the most elongated of the three galaxies. It is pretty bright, large and has a somewhat brighter core in the 17.5" at 200X. Averted vision will bring out a hint of a dark lane on a sharp, transparent night. NGC 3344 8"--faint and somewhat diffuse, no detail, 2 * invl NGC 3432 8"--small, faint, narrow streak that appears to connect two * NGC 2683 bright, pretty large, much elongated east-west and much brighter in the middle at 100X. NGC 2244 is the star cluster involved in the Rosette. In the 13" at 60X it consists of 2 parallel lines of about 15 stars. It is very bright, very large and not compressed. Several of the stars are yellow and one is a lovely orange. NGC 2261
is Hubble's Variable Nebula. Edwin Hubble took many photos of this comet-shaped
nebula that show changes in its form. NGC 6369 is a very nice planetary. It can be spotted in an eight incher at 100X, but large scopes work well on this object. The 18" at 175X will show a central dark spot and at 300X this object starts to look somewhat like the Ring Nebula. This annulus effect could be seen in a 13" at 200X on the same night. NGC 6572 is a pretty small and bright planetary. It is somewhat elongated and the central star will appear during good seeing at 300X in the 18". Other times the center will just brighten up somewhat. The noteworthy aspect of this gem is its' color. In every scope I have ever owned, from an 8" to an 18" this is the greenest nebula I have ever seen! This guy is as green as an Irishman's coat on St. Patrick's day. Alright, alright, it is as green as lime Jello. NGC 6633 has 15 stars of mags 9 and 10 within a 20' field. Then there is another 30 to 35 stars of mags 11 and down which form a lovely backround at 100X. This is a nice cluster with a 7th mag star on the south side. NGC 1788 is pretty faint, pretty large, irregular in shape at 100X. It looks like a paint splatter with a bright star at the edge. NGC 1973 is a bright, large nebulosity that has several stars involved at 100X. The fainter parts of the nebula extend beyond the 30" field. NGC 2024
is a bright, large emmision nebula near Zeta Ori. It is easy in any telescope
I have ever used under dark skies and my old 8" f/6 would show several
dark lanes winding across this nebulosity. NGC 2022 is a pretty small, not very bright planetary. It can be noticed in the 17.5" at 50X. At 200X, it is a greenish dot with no internal detail. NGC 2194 is a bright, pretty rich, compressed open cluster that is well resolved in the 17.5" at 100X. The cluster has a flattened shape. NGC 7331 is bright, large, very elongated and has a much brighter nucleus at 135X. It is just discernable in the 10X50 Binocs. Has several companion galaxies. NGC 884
and NGC 869the Double
Cluster is naked eye as a bright spot in the Winter Milky Way from even
a somewhat light polluted site. NGC 1491 Pretty faint, pretty large, irregularly round at 135X using a UHC filter. The central star appears about 10th magnitude. This nebula is quite faint without the UHC, I just noticed it, even from a dark site. NGC 1023 Pretty bright, large, much elongated, bright middle at 135X. Raising the power to 200X brings out a small tuft on the Eastern tip of this galaxy. NGC 2438 Bright, large, irregularly round at 220X. Central star easy at all powers. Going to 440X with the Barlow shows two other stars involved in this nebula. At 100X the nebula is light green, but the color is dim at high power. NGC 2440 Bright, pretty large, much brighter in the middle at 270X. The central star becomes stellar occaisonally in good seeing. Averted vision doubles the size of this planetary. This object is elongated 3 X 1 in PA 30. It is a very nice lime green at all powers. NGC 2539
Bright, large, rich, stars 10th to 13th mag. NGC 253
is the star of the show in Sculptor. NGC 6712
bright, little elongated, very rich, very compressed. NGC 3115 17.5"-- Bright, Very elongated, Very bright middle, stellar nucleus at 135X NGC 6445
is a nice planetary, 20 minutes North Following 6440. NGC 6520 is a pretty bright open cluster but it is pretty small with about 20 members at 165X. NGC 6818
is a bright, pretty small and little elongated planetary. NGC 2841 Pretty bright, pretty large, Bright nucleus with several stars involved in northern arm at 135X. NGC 3079 Bright, pretty large, very much elongated in PA 150, bright middle at 165X. A difficult dark lane comes and goes with the seeing. Two stars are invl on the north end. There is an extremely faint, round companion to the north about 5'. NGC 3077 Bright, large, somewhat elongated and much brighter in middle at 165X. Very starry field for UMA. NGC 3184 Pretty bright, pretty large, round, bright middle at 165X. 11th mag star on north side. There is a hint of spiral structure in moments of good seeing. NGC 3675 Bright, pretty large, much elongated in PA 0 with a much brigther middle at 100X. Going to 165X brings out a stellar nucleus and several stars involved. NGC 3877 Pretty bright, pretty large, much elongated in PA 35, much brighter middle at 100X. Chi UMA in the field. NGC 3941 Bright, pretty large, round and much brighter in the middle at 165X. Averted vision helps on this mottled galaxy. NGC 4026 Bright, large, elongated 3 X 1 N-S, with a somewhat brighter middle, it shows a nice lens shape at 135X. NGC 4088 Bright, large and assymetrically elongated 3 X 1 in PA 45, somewhat brighter middle at 100X. NGC 4605
Bright, pretty large, much elongated (3X1) in PA 110. NGC 4216
pretty bright, large, much elongated with a very bright middle at 100X. NGC 4388
pretty bright, large, much elongated 3X1 E-W, brighter middle. NGC 4438 bright, pretty large, very much elongated, much brighter in the middle. 4438 and 4435 are elongated in the same PA. NGC 4526 Bright, large, much elongated (3X1) in PA 110 with a much brighter middle and a stellar nucleus at 165X. NGC 4535 Pretty bright, large, elongated 1.5 X 1 in PA 0 with a bright middle and a stellar nucleus at 165X. There are several stars involved in this stellar nucleus. NGC 4567
and 4568are the famous
Siamese Twins galaxies. This pair is pretty bright, pretty large, irregularly
round and brighter in the middle at 165X. These two galaxies are joined
at the eastern end and form a "V" shape to the west. There is
a NGC 4699 Pretty bright, pretty large, round and much brighter in the middle at 100X. Has a high surface brightness central section and averted vision makes it grow in size. NGC 4762 Bright, large, much elongated (4X1) in PA 30 with a bright middle and a hint of a dark lane at 135X. There is pretty bright, round companion in the field to the west. NGC 5746 bright, large, much brighter middle, much elongated north-south. There is an obvious central bulge at 135X. A dark lane cuts across the galaxy in moments of good seeing. NGC 6940 Bright, large, rich, quite compressed at 100X. This cluster is easy in the 11 X 80 finder. I estimated 80 members, many in lovely chains of stars. There is an interresting feature of this cluster, it is bordered in black. A dark lane goes almost all the way around the dense star cluster, as if the stars were gathered up and left behind dark lanes. |
