Aquila
6804
NGC 6804 6" f/6 Maksutov-Newtonian Camp 613 S=7, T=9 34mm just barely
detected at low power. Extremely faint, pretty small, not brighter in
the middle, round. 14mm now held steady at least, a little more "comet
shaped", but tough to hold that shape because it is so faint. 8.8mm
best view, most contrast, shape is round pretty consistently. UHC helps
somewhat, but you must have some photons to filter.
NGC 6804 13" f/5.6 Newtonian Dugas Rd. on a 7/10 night; Pretty bright,
pretty large, round, noticed at 135X. At 220X, 4 stars involved
including 12th mag on the eastern edge. Averted vision elongates the
nebula, the pretty bright star involved also makes the nebula appear
comet shaped when with direct vision it is round.
NGC 6804 13" f/5.6 Cherry Rd. S+T=7 220X no filter--4 stars are involved
in nebula, the one at the "tip" is the brightest by far. Averted vision
makes it change shape a little. Add UHC filter--the filter gets rid of
all the stars except the one at the tip, now the shape is little
elongated 1.2X1 in PA 20. The nebula is much more contrasty with the
filter.
NGC 6804 16" f/4.5 Antennas S=6, T=8 14mm pretty bright, pretty small,
very little elongated 1.2X1, 11th magnitude star on the northeast edge.
It is seen as an evenly illuminated disk. 8.8mm now there are three
stars involved within the disk.
NGC 6804 17.5" f/4.5 Dugas Rd. S=6, T=7 Bright, pretty large, comet
shaped at 100X. Using over 200X shows a star at the tip of the comet
shape and another dimmer star involved to the west. A nice object at
high power.
Ultimate Star Party, McDonald Obs., Oct. 95, S=7, T=9, 36" f/5--
NGC 6804 36" 16mm and UHC; 7 stars involved, central star held for 20
percent of the time, central bright region is mottled and shows lots of
fine detail, bright and dark regions that are small, but held steady, a
unique object. There is a brighter diamond-shaped central region and
then fainter outer region which makes the entire object round.
Cygnus
Veil Nebula
NGC 6960 4" f/6 refractor Cherry Rd. S+T=6 Not as easy as the other
section of the Veil (NGC 6992). The star 52 Cygni makes it somewhat
more difficult to see the streamer of nebulosity at low power. Using
the 22mm Panoptic and a UHC filter makes it easier to see, the star is
dimmer through the filter and the nebula is enhanced. The "pointy end"
of this part of the Veil is higher in surface brightness than the
"split" end.
NGC 6960 TV 102 Antennas S=7, T=8 27mm + UHC pretty bright, very large,
very elongated 4X1, includes 52 Cyg, averted vision makes it more
prominent.
NGC 6960 6" f/8 Antennas S+T=7 27mm faint, large, extremely elongated,
52 Cygni in the middle. Add UHC filter makes a Wow difference. Now the
"pointy end" is easily seen, as is the "broom end". There is a division
at the wider end that was not seen without the filter.
NGC 6960 with 52 Cyg, 13" f/5.6 Sedona S+T=8 35mm+ UHC is a fun view,
but no detail. At low power the "split tail" section is difficult and
needs averted vision to see split detail. Going to the 14mm and UHC
shows the detail of the split and brighter areas much better. Hickey is
a triangular section in the middle. 14mm and UHC show it as very faint,
large, triangular in shape and brighter on the eastern side. It is only
seen with UHC. There are 8 stars involved with the UHC in place.
Averted vision does helps the contrast of this dim section of a famous
nebula.
NGC 6960 and 6992 are the brighter parts of the Veil Nebula. These two
nebulae were created by a supernova about 30,000 years ago and we just
happen to be lucky enough to live while it is visible. 6960 passes
behind 52 Cygni, a naked eye star off the western wing of the Swan.
This section can be seen to split into forked branches. 6992 is about 2
degrees from 52 Cygni and is somewhat brighter than 6960. In my 17.5"
with a 20mm Erfle and a UHC filter, the Veil is amazing. Only about one
quarter of either loop can fit into the field of view and the scope must
be scanned to see all that is available. 6992 has loops and swirls of
nebulosity that give a three dimensional effect. There are other pieces
to the Veil Nebula, most of them between the two main sections, much of
what can be photographed in an 8" Schmidt Camera can be viewed by a
persistent observer. This is the object on which the UHC filter does
its best work.
Ultimate Star Party, McDonald Obs., Oct. 95, S=7, T=9, 36" f/5--
NGC 6992 Veil 27mm and O III; WOW!!!! Eve says "Wow" from the top of
ladder; Dennis and I are giving up trying to come up with superlatives
about this object in the 36". Primo view, my finest view of any object
at any time in any telescope. The Veil looks like a three dimensional
taffy machine. Mottling, smooth sections with stars involved of a wide
variety of magnitudes. There are several places where you can see small
chunks of nebulae detached from the main body of the Veil.
NGC 6992 TV 102 Antennas 35mm Panoptic and 2" UHC filter great view,
bright, large, extremely elongated 8X1, long curved loop of nebulosity.
The entire section fits in the refractor with this eyepiece and filter
combination.
NGC 6992 Veil 6" f/6 Maksutov-Newtonian Sentinel 8/10 22mm+UHC is a
great view, the "Dragon Head" section is easy and the twisted "taffy
pull" structure is only hinted at, must take some aperture. 14mm+UHC
better view of detail, the twisted section shows some structure with
direct vision. This portion 6992 has higher surface brightness than the
52 Cyg part. This side of the Veil Nebula appears to me like the curved
blade of a sickle or Arabian sword.
NGC 6992 6" f/8 refractor S+T=7 27mm Panoptic and 2" UHC filter Antennas
WOW! the field of view is the entire arc of this portion of the Veil.
It is bright, very large and extremely elongated. The "Dragon's Head"
feature is easy to see. I count 15 stars involved within the nebula.
NGC 6992 16" f/4.5 Five Mile Meadow S=7, T=7 27mm + UHC filter bright,
very large, extremely elongated, at least 2 fields of view long. The
"Dragon's Head" feature is fascinating, lots of detail. Going to the
14mm UWA eyepiece and the UHC shows an amazing amount of detail, the
Veil is 4 fields long and I count 52 stars involved. A great view of a
favorite object.
6811
NGC 6811 10X50 binocs Antennas S+T=7 pretty bright, pretty well
detached, seen easily, no stars resolved, elongated glow 1.2X1 E-W,
averted vision makes it larger.
NGC 6811 15X70 binoculars AZ Sky village S+T=7 pretty easy to see, 4
stars with a definite fuzzy background.
NGC 6811 4" f/6 refractor Cherry Rd S=6 T=5, 14mm EP, pretty large,
pretty rich, somewhat compressed, pretty compact, pretty well detached.
I counted 22 stars at 45X.
NGC 6811 6" f/8 refractor Antennas S+T=7 14mm pretty bright, large,
little compressed, pretty rich, 39 stars counted. Pretty well detached.
There is an interesting circlet of 7 stars on the NW edge.
NGC 6811 10" f/5 Antennas 22mm Panoptic pretty bright, pretty large,
rich, compressed. Stands out well from Milky Way, well detached.
14mm--54 stars counted, dark lane cuts it down the middle.
NGC 6811 13" f/5.6 Cherry Rd. S+T=7 Pretty rich, large, somewhat
compressed, 42 stars counted of 10th mag and dimmer at 100X.
NGC 6811 16" f/4.5 Antennas site S+T=6 22mm pretty bright, prety large,
somewhat compressed and somewhat rich. 41 stars are resolved and
several chains are resolved. This cluster is moderately detached from
the Milky Way background.
6819
NGC 6819 TV 102 5 Mile Meadow S=7, T=8 8.8mm pretty faint, pretty large,
irregular figure, 16 stars are resolved in a horseshoe shape, averted
vision adds another 10 stars and fills in the cluster.
NGC 6819 4" f/6 refractor Az sky village S+T=7 8mm EP pretty bright,
large, compressed, 8 stars resolved. There are 2 lines of 4 stars each,
with a very fuzzy background of "oatmeal" faint stars.
NGC 6819 4" f/6 refractor Cherry Rd S=6 T=5, pretty large cluster,
pretty rich, compressed, "V" shaped, well detached.
NGC 6819 6" f/6 Maksutov-Newtonian Antennas S=6 T=7 14mm bright, pretty
large, irregularly round, compressed, 9 stars and a fuzzy background.
6.7mm 14 stars resolved, averted vision shows another 5, there is a
delicate double star on the SW edge. This cluster is in a very rich
field of view. But, in Cygnus, what isn't?
NGC 6819 6" f/8 refractor Antennas S+T=7 14mm pretty bright, large,
compressed, rich. I counted 28 stars with a very fuzzy background.
There is a prominent "V" shape of stars in the cluster on the north
side. Averted vision shows twice as many stars and doubles the size of
this cluster.
NGC 6819 10" f/5 Antennas S+T=7 14mm-pretty bright, pretty small, pretty
rich, compressed, "V" shaped cluster, 14 stars and fuzzy background,
averted vision makes it grow. 6.7mm--26 stars counted, final 10 very
faint stars come and go with seeing, many stars at the limit of the 10
incher.
NGC 6819 Nexstar 11 Flatiron S+T=5, great cluster, 48 stars mags 11.....
rich, compact, "V" shape of brightest stars with a rich background of
fainter members. Averted vision makes a real difference in the
appearance...many fainter stars with averted vision.
NGC 6819 13" f/5.6 Cherry Rd. S+T=7 Bright, pretty large, much
compressed and very rich cluster. 32 stars counted at 165X, many close
groupings. There is a nice "oatmeal" background, even at higher powers.
A light orange star of 11th mag in on the east side.
NGC 6819 16" f/4.5 Five Mile Meadow S=7, T=7 8.8mm pretty bright, pretty
large, pretty rich and compressed. There are 38 stars resolved with a
fuzzy background.
7000
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. In a 4 1/4" f/4 with a 20mm Erfle and a UHC
filter, the nebula is very bright and very large, filling the 1.5 degree
field with nebulosity. The brightest section is "Mexico" and the
Pelican Nebula (IC 5067) can be seen nearby.
NGC 7000 10X50 Leupold binocs North Ranch T=5 pretty bright, very
large, the North America shape is easy to see, there are 19 stars
involved within the nebula, there is an obvious orange star (Xi Cygni)
to the west of the nebula.
NGC 7000 20X80 binoculars 5 Mile Meadow S+T=7 pretty bright, very large,
about 90% of the field of view of the big binoculars, the North America
figure is pretty easy, there are 30 stars involved in the nebula.
NGC 7000 Vixen ED80 Antennas site 27mm Panoptic and UHC filter provides
a nice view of the North America Nebula. It is pretty bright, extremely
large, has a very irregular figure and shows 38 stars involved. The
North America outline is obvious. The cluster within the nebula is
obvious, it is viewed as a bright spot near "Detroit".
NGC 7000 4" f/6 RFT refractor Az Sky Village S=6, T=8 35mm Pan and 2"
UHC WOWOOWWOWOEE A great view of the famous shape. Bright, very, very
Large, very irregular figure (North America), 41 stars involved. The
dark lane on the east side that cuts off the nebula is very prominent
and has an orange star involved. The section that is "Mexico" is the
brightest, nice high surface brightness. The Pelican nebula is easily
seen at the edge of the field. The star density on the north side of
the nebula is amazing, lots of faint and very faint stars, it is more
obvious with the filter removed and the 22mm Panoptic filter. Without
the filter the nebula is much fainter, but the starry glow is
fascinating from this dark site.
NGC 7000 TV 102 Antennas S+T=7 35mm Panoptic and 2" UHC filter bright,
very large, very irregular filter, 48 stars involved within the glow.
This set up of TV 102, 35mm Pan and 2 inch UHC really shows this object
to its best.
NGC 7000 6" f/6 Maksutov-Newtonian Cherry Road S=7 T=8 with the 38mm
eyepiece the entire North American shape is easy, the Pelican can just
be seen. It is pretty faint, extremely large, irregular figure with
many stars involved. The "Mexico" section is the most obvious. The
star cluster NGC 6997 is pretty bright, pretty large and somewhat
compressed with 11 stars resolved in the 6 incher. Going to a 22mm Pan
shows the cluster having 18 stars resolved, 8 are very faint and there
is an obvious glow on un-resolved stars around the cluster. Either
Mexico or the Pelican fills the field at this power and the area to the
north of the N.A. figure is very rich in a profusion of stars.
NGC 7000 16" f/4.5 Antennas site S+T=7 35mm Panoptic no filter shows
the nebulosity but it is not obvious in most locations. Adding the 2"
UHC makes a tremendous difference, now the nebulosity is easily seen as
extremely large, pretty bright, very irregular filter and has about 100
stars involved within the glow. Mexico is the brightest part of the
nebula and Florida is pretty easy.
Lacerta
7209
NGC 7209 TV 102 Antennas S=6, T=8 14mm pretty bright, pretty large, not
compressed, 22 stars resolved magnitudes 8...11. Pretty well detached,

curving chain of stars, a unique cluster layout. Pretty well detached.
NGC 7209 8" SCT Antennas 22mm Pan S+T=7 Pretty large, considerably
rich, little compressed. I counted 36 stars in two groups, averted
vision added 5 more stars. The two groups are connected by a curved
chain of stars. This cluster is pretty well detached.
NGC 7209 Nexstar 11 Cherry Rd S=6 T=7 125X bright, large, pretty rich,
somewhat compressed, 48 stars of mags 9..12, a long chain of stars an
unusual cluster shape.
NGC 7209 13" f/5.6 Dugas Rd S=5, T=6 Bright, large, rich, pretty
compressed in a 15 arc minute area at 100X. I counted 59 stars, many in
lovely chains that fade out into a Milky Way background. There is a
smooth progression of magnitudes from 9th to 12th within this cluster.
NGC 7209 16" f/4.5 Antennas S=6, T=8 14mm pretty bright, pretty large,
considerably rich, pretty compressed, 22 stars resolved. This cluster
is pretty well detached from the Milky Way background. There is a nice
chain of 9 stars and the rest of the cluster nearby. There is a light
orange star on the south side.
NGC 7209 17.5" f/4.5 Sentinel S+T=8/10 8X50 finder easy, 4 stars and
some fuzz. 60X--Bright, large, rich, somewhat compressed, several dark
lanes in field. 51 stars counted, mags 10..... several nice chains and
pairs.
7243
NGC 7243 10X50 binocs Antennas S+T=7 pretty bright, pretty large,
triangular, 3 pretty bright stars in a straight line through cluster
center, another 3 stars seen with averted vision only, pretty well
detached.

NGC 7243 6" f/6 Maksutov-Newtonian Flatiron S+T=6 14mm EP pretty bright,
pretty large, somewhat compressed, 33 stars mags 8..12. Averted vision
shows many fainter members. The Struve double is dead center, it is
just split at this power.
NGC 7243 6" f/8 Antennas S+T=7 14mm pretty large, little rich, not
compressed, 26 stars resolved including one almost matched pair. Not
very well detached.
NGC 7243 8" SCT Antennas 22mm Pan S+T=7 Pretty large, considerably
rich, somewhat compressed. I counted 34 stars, averted vision added 5
more stars. There is a Struve matched pair included and a faint fuzzy
background of unresolved stars. This cluster is moderately well
detached.
NGC 7243 Nexstar 11 Cherry Rd S=6 T=7 80X bright pretty large, somewhat
rich, not compressed, 39 stars mags 10...13, few faint members, double
star is easily split. Moderately detached from Milky Way.
NGC 7243 Nexstar 11 Sentinel S=5 T=7 22mm Panoptic EP there are two
sections to this cluster, 44 stars counted total. Pretty bright, large,
pretty rich, little compressed and somewhat detached. The Struve dbl
that is included is a matched pair about 11th mag.
NGC 7243 13" f/5.6 Dugas Rd S=5, T=6 Bright, large and not compressed at
100X. 39 stars were counted in this rather coarse cluster. A dark lane
divides the cluster into 1/3 and 2/3 groups.
NGC 7243 13" f/5.6 Sentinel 8/10 S+T 60X Bright cluster, very large,
not compressed, 66 stars counted mags 9...., many pretty bright stars
involved. Lovely yellow-yellow double star in center of cluster.
IC 5217
IC 5217 13" f/5.6 Sentinel S=6 T=8 Pretty faint, small, round and not
brighter in the middle at 135X. This gray dot is about twice the size
of the seeing disk and grows with averted vision. In a nice Milky Way
field at 150X. There is a faint star on the NE edge--not the central
star. It has a pretty tough low surface brightness disk at 220X.
7296
NGC 7296 6" f/8 Antennas S+T=7 8.8mm faint, pretty small, not rich and
compressed. 11 stars are seen with direct vision and another 5 with
averted vision. There is a fuzzy background all the time I observed it.
NGC 7296 13" f/5.6 Dugas Rd S=5, T=6 Pretty bright, small and not
compressed. I counted 18 stars at 200X. This group is fan-shaped and
there is a nice yellow star at the apex of the fan.
NGC 7296 13" f/5.6 Sentinel S=6 T=8 100X--pretty bright, pretty large,
somewhat rich, little compressed. 19 stars counted mags 10...13. They
form a "fish-hook" loop of stars with a nice double star in the inside
of the hook.
7245
NGC 7245 100mm f/6 refractor Cherry Rd S=6 T=7 very faint and pretty
small with 14mm EP, only a fuzzy oval with about 3 star resolved. I
would have never found it if the RFT was not piggy backed on the Nexstar
11.
NGC 7245 6" f/8 Antennas S+T=7 14mm faint, pretty small, very little
brighter middle, 2 stars resolved with direct vision, another 2 with
averted vision, very difficult. Just a low surface brightness glow and
some grainyness with averted vision.
NGC 7245 Nexstar 11 Cherry Rd S=6 T=7 80X Faint, pretty large, somewhat
compressed, not rich, 12 stars mag 11 and 12 with very fuzzy background,
averted vision shows another 10 stars involved. Going up to 200X with
the 14mm, lets me count 26 stars and another 5 to 10 come and go with
the seeing. There are lots of very faint members just at the limit of
resolution. This cluster is poorly detached from the Milky Way.
NGC 7245 Nexstar 11 Sentinel S=5 T=7 22mm Pan 28 stars resolved in a
background of finest stardust, averted vision shows another dozen or so
stars right at the limit of resolution. Pretty faint, large,
compressed, little rich, very little brighter middle.
IC 1434
IC 1434 100mm f/6 refractor Cherry Rd S=6 T=7 14mm UWA 9 stars and
mottled background. Averted vision helps a little--but this cluster is
not well detached. This is a Very rich field of view in the RFT
refractor, WOW.
IC 1434 6" f/8 Antennas S+T=7 14mm pretty small, faint, pretty
compressed, 19 stars resolved with a very fuzzy background, an almost
mottled appearance. Averted vision doubles the size of this cluster and
hints at the "branched" structure mentioned in the IC notes.
IC 1434 Nexstar 11 Cherry Rd S=6 T=7 125X pretty bright, pretty large,
compressed, pretty rich, 40 stars mags 11 and fainter. Moderately well
detached, there are several chains of stars that loop from the central
section out into the Milky Way, a nice cluster.
IC 1434 Nexstar 11 Sentinel S=5 T=7 22mm Panoptic EP 46 stars and fuzzy
background. Pretty bright, pretty large, rich, somewhat compressed,
lovely chains of stars of magnitudes 10 and fainter.
IC 1434 13" f/5.6 Sentinel S=6 T=8 Pretty faint, pretty large and
irregularly round at 100X. On a mediocre night, rated S+T=6, this
cluster is not rich with 22 stars counted but several dark lanes pass in
front of the area making black "fingers" that penetrate this grouping.
On a much better night I counted 38 stars as members of this cluster and
saw it as pretty rich and considerably compressed at 150X. This cluster
showed off several lovely curved chains of stars.
