13.1" f/5.6 unless noted
NGC 40 bright, 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 and
brighter. From a poorer site on a night I rated 5/10 for seeing and
transparency, the brighter parts of the planetary make it appear to
have a spiral shape. The "polar cap" effect only appears on
best of nights.
Ultimate Star Party, McDonald Obs. Oct. 95, S=6, T=8, 25"
NGC 40 in 36" with 11mm,
light grey-green and absolutely gorgeous.
The ring around the outer section is not complete, so that the
"polar caps" that I have mentioned before are obvious. Larry
they are parts of the nebula that are "blown out" and I agree
is what they seem to be. Bright star at 2 o'clock and a dimmer one
at 8 o'clock could be knots of material that are being ejected.
Going to the 9mm eyepiece shows the central section as quite
mottled, an effect only suspected at lower power.
Sentinel S=8 T=9 Great night 100X Faint, pretty small, round,
central star obvious. 220X--"spiral structure" seen, there are
several dark markings that curve around the central star. 440X best
view there is an extremely faint star right at the edge of the neby.
This planetary is grey in color at all powers. The "polar caps"
obvious, even with direct vision.
NGC 188 pretty faint, large,
compressed at 100X. I counted 30
stars in a very fuzzy background. It appears that the dimmer
cluster members are not resolved at any power up to 270X in the 13".
NGC 2276 Faint, pretty small,
little brighter middle, little
elongated 1.2 X 1 in PA 0 at 135X.
NGC 2300 Pretty bright, pretty
small, little elongated 1.5 X 1 in
PA 165, much brighter middle at 135X
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. Sentinel
8/10 S+T 13" 60X--large, bright, rich, compressed middle, 12 stars
resolved, but lot of stars unresolved fuzz. 150X--65 stars resolved
in this nice view. Beautiful, delicate blue-gold binary pair to NE
of cluster. There is a dark lane on the south side really cuts off
the stars on that side. 220X doesn't help.
Sentinel S=6 T=7 6" f/6 22mm--bright, large, round,
much compressed, 12 stars resolved. 14mm--best view, 15 stars
resolved, averted vision shows a much larger cluster with a
somewhat brighter middle. 8.8mm--22 stars resolved, pretty bright
chain of stars down the middle of the cluster.
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
I rated 5/10 and then called it "pretty bright" on a night that
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 seen spiral structure in this
object. There is a very dim extension that forms a 'V' shape.
Ultimate Star Party, McDonald Obs. Oct. 95, S=6, T=8, 25"
NGC 6946 in 25" shows easily
my best view of this object. Three
spiral arms are obvious and there are 16 stars involved. Several of
these knots are much larger than the seeing disk. Rich Milky Way
field in 20mm Nagler.
13" f/5.6 Sentinel 8/10 S+T 11X80-just detected, better
averted vision. 60X in 13" -Galaxy and Cluster in same field
with room to spare. 100X-pretty faint, large, somewhat brighter
in the middle, hint of spiral structure. 150X- the spiral detail
is more obvious, central core large and high surface brightness.
NGC 6949 Extremely faint, small, round and
not brighter in the
middle at 165X. It comes and goes with the seeing.
NGC 6951 pretty bright, pretty
large, elongated 1.5X1 in PA 75,
much brighter middle at 165X. There is an 11th mag star on Eastern
NGC 7023 Bright, Large, elongated
(2X1) in PA 0, irregularly shaped
nebulosity seen immediately at 100X. Central section does not
contact the central star. UHC filter makes the nebula smaller, this
object must have a bizarre spectrum. The field has a dim glow from
outer sections of the nebulosity. This nebula is in a portion of
the Milky Way that is much obscured by dark nebulae.
IC 1396 very, very large, very
faint nebula that needs low power to
fit it into a single field of view. I used a 38mm military Erfle in
a 2" barrel that gives one degree in the 13" and yields about
Even at that, it just fits. I had missed seeing the nebula on a
previous observing session because I was using a 20mm Erfle in a 1
1/4" barrel, so haul out that wide angle piece of glass for this
object. There are several dark lanes winding through the nebula.
The UHC filter helps a little.
Vicksberg 7/10 S+T binoculars 11X80-- 19 stars counted,
5 stars are very faint, the nebulosity is not seen. The cluster is somewhat
scattered, even with big binoculars.
NGC 7076 Very faint, pretty
small, round, just seen at 100X in the
13" f/5.6. It is somewhat more contrasty at 150X, but never easy;
going to 220X is too much power and the nebula almost disappears.
The UHC filter does not help the visibility of this nebula,
but averted vision makes it much more visible. This on an
excellent night at Sentinel.
7129 This NGC number is applied
to both a cluster and nebula.
11X80 just seen as fuzzy spot. At 100X the cluster is pretty
bright, pretty large, very poor in stars. I counted 6 stars in
a 10 arcmin area. The nebula at 100X is pretty bright, pretty
large with an irregular figure. Of the 6 stars in the cluster,
4 or them are involved within the nebula. Averted vision makes
it much easier to see the nebula. Going to 150X helps the contrast
somewhat, and 220X is too much for the nebula, but I can see 2
very faint stars in the center that were missed at lower power.
The UHC filter does not help.
NGC 7133 is near NGC 7129, it
is faint, small and round with 2
pretty faint stars involved.
7139 very faint, pretty small,
not brighter in the middle, a dim
grey dot at 100X. UHC filter brings up the contrast somewhat, but
this object is still not much. There is a 12th mag. star to SW. It
is a little better, but still not easy, at 220X. The disk is
larger, but never bright on this low surface brightness object.
7142 pretty bright, large, not
compressed, rich cluster of 30 stars
7160 bright, pretty large, scattered
group of 16 stars at 135X.
Two 9th mag stars and several fainter ones, not much.
7235 pretty bright, pretty small,
somewhat compressed cluster at
165X. One pretty bright star with 20 others.
7261 pretty bright, pretty small,
rich, compressed cluster of 30
stars at 165X. It was seen in the 11X80 finder. Of the clusters
within the "Pentangle" of Cepheus, this was the best.
7281 pretty faint, pretty small,
not compressed, scattered group of
18 stars at 165X.
NGC 7354 Pretty bright, pretty
large, somewhat brighter middle,
little elongated 1.2 X 1 in PA 165 at 135X. No central star was
seen in this planetary at 220X. I dispute the magnitude given
for this nice nebula, the data is given as 12.9 mag, I estimate
approximately 11th mag.
7380 pretty bright, pretty large,
triangularly-shaped cluster of 36 stars at 100X. There is
nebulosity involved in the cluster, it can be seen without the UHC
filter, but the filter helps the contrast very much. The nebula is
dim enough that when I use my red flashlight to take notes, the
nebula disappears for a few moments when I return to the eyepiece.
IC 1470 pretty bright, pretty
small, comet-shaped nebula at 165X.
There is a star at the apex of the comet shape. UHC does not help
NGC 7419 Pretty bright, pretty
large, pretty rich, compressed, I
counted 11 stars at 135X. This cluster has an irregular, comet
shape and a very grainy background of unresolved stars.
7510 bright, pretty large, somewhat
compressed cluster at 165X. I
counted 22 members in an irregular shape, with several nice lines of
stars. In a wide field eyepiece, cluster King 19 is in the same
King 19 pretty faint, pretty
small, not compressed cluster of 12
stars at 165X. I counted 12 stars as members.
7538 pretty bright, pretty large,
roundish nebula at 135X. There
are two noticeably bright stars involved, which reminds me of the
glowing eyes of the "Jawa" creatures in the Star Wars movies.
7762 pretty bright, pretty large,
irregularly shaped, scattered
cluster of 25 stars at 100X. The cluster is not compressed at any
7822 very faint, very large,
elongated nebula at 100X with the UHC
filter. It could not be detected without the filter. The eastern
side seemed brighter. On another night from an excellent site in at
6000 ft. altitude in the Mogollon Rim country of Eastern Arizona, it
was Extremely faint, extremely large, very elongated 3 X 1 in PA 90
and not brighter in the middle at 80X. The nebulosity extends
beyond the 40' field of my eyepiece. Using the UHC filter, it could
be glimpsed in the 11X80 finder. This nebula has an very low
surface brightness and is huge in size.
IC 1454 Faint, pretty large,
round, very diffuse nebula with a
pretty bright star on one side. Just a smudge at 100X. Looking at
the sheet of paper to write these notes, makes it disappear for a
Cederblad 214 very, very faint,
very, very large nebula. It is
not much, just a field brightening at 100X with the UHC.
Berk 59 faint, small, not compressed.
12 faint stars at 135X.
Berk 94 Pretty faint, small,
not rich, considerably compressed at
165X. I counted 17 stars, with a nice orange 10th mag star about 5
arc minutes east of the center of the cluster.
Berk 99 Faint, pretty small,
elongated, not rich, compressed at
165X. 3 stars and some haze in the background.
PK116+8.1 Very faint, pretty
small, round, little brighter in the
middle at 220X. It was just barely noticed without the UHC filter,
adding the filter helps the contrast a lot.
PK 103+0.1 Pretty faint, pretty
large, round, grey, central star
seen at all powers. It was detected at 165X, but better after
adding the Barlow to go to 320X. There is a star on the eastern
side which is about the same magnitude as the central star. The UHC
filter does not help this object.
Reiland's Object The Nov. 88
issue of Sky and Telescope contains a
discussion in Deep Sky Wonders of a new cluster discovered by an
amateur with an 8" scope. This tiny cluster is 12' south and
slightly west of IC 1470. I found this object to be small, pretty
faint, somewhat elongated and not brighter in the middle at 100X.
At 165X, 4 stars are resolved and averted vision makes it grow in
size. There is a hint of nebulosity and the UHC filter improves the
Mu Cephei is "Herschel's Garnet Star",
a famous tinted sun in Our
Galaxy. It appears a ruddy shade even to my naked eye. I found it a
very nice yellow-orange color at the end of a fish hook of stars.
Kappa easy split at 100X, blue
Beta Cephei easy split at 100X,
white and beautiful emerald. A
Delta split in 11 X 80 finder,
yellowish and light blue.
Omicron Cephei Clean split at
165X, white and grey.
Xi Cephei Easy at 100X, white
and light green.
Struve 2816 easy at 100X. A
nice triple system. A white sixth mag
star flanked on each side by an 8th mag blue star. Very nice. It
is involved in IC 1396.
Struve 2840 Easy at 100X, white
and light blue.
Struve 2873 easy at 100X. Almost
matched yellow pair. I built
Dobsonians for several years and had forgotten how tough a German
mount is near the Pole.
Struve 2948 elongated at 100X,
not an easy split at 165X. Only clean
separation in moments of good seeing, both white.
Otto Struve 440 easy at 100X,
yellow and light blue.
