AURIGA
by Steve Coe
13" f/5.6 unless noted

NGC 1664 Pretty bright, pretty large, not rich, not compressed. Seen in 11X80 finder. 30 Stars counted in 13" at 135X. There is an 8th mag star on the south side of cluster, with a nice chain of fainter stars leading to it.

NGC 1778 Pretty bright, pretty large, not rich, not compressed. Not much at 135X, 18 stars in straggling clumps.

NGC 1798 is a class 7 "nonexistent" cluster in the RNGC and is not
plotted on any star chart I own. However, it is pretty bright,
pretty large and not compressed at 100X. Raising the power to 165X
resolves 20 stars with a dark lane in the center. Add this lost
cluster to your observing list.

IC 405 Pretty bright, pretty small, round nebulosity surrounding
AE AUR. Can be seen without UHC, but filter helps contrast.

NGC 1857 Bright and Rich. Very nice at 165X, an 8th mag yellow
star with several nice star chains radiating out from it. 45
members counted in about 12 minutes of cluster size.

Granite Wash Mt. S=7 T=8 13" 100X--easily seen as cluster.
150X--pretty bright, pretty large, pretty rich, somewhat compressed,
38 stars counted, including an 8th mag. yellow star near center of
cluster. There are many faint members that are easier at high power,
including several beautiful chains of stars.

Eagle Eye 6" f/6 S+T=7 40X--just seen as cluster, fuzzball with 7 stars resolved. It is a cluster, but not rich, small and little compressed. 65X--does not help much, 7 stars and another 5 seen with averted vision.

Berk 18 Faint, large, rich, not compressed at 100X. King 22 and
Berk 18 overlap and I have no idea where one starts and the other
begins. The entire area has lots of faint stars and a grainy
background glow.

NGC 1883 pretty faint, small, irregularly round, pretty compressed.
Averted vision shows a very grainy background with 12 stars resolved at
165X.

Sharpless 224 extremely faint, pretty large. Two parts to the
nebulosity with 5 stars involved at 100X with the UHC filter. Both
pieces are quite elongated. At the limit of the 13" with the filter.

NGC 1893 Bright, pretty large, not compressed. I counted 61 stars in
cluster, several nice chains. Just seen in 11X80 finder.

Do 16 13 * counted at 150X, pretty faint, not rich, not compressed.

Do 18 11 * counted at 150X, pretty faint, not rich, not compressed,
a few very faint members and several 11th mag stars.

IC 410 Without UHC filter it is faint, large and irregular. Using
the UHC it is pretty bright and obvious at 100X. In either case it
surrounds the cluster NGC 1893 and is more easily spotted on the south
and west sides.

NGC 1907 pretty bright, pretty small, much compressed and resolved
at 165X. Just seen in 11X80 finder, I counted 22 stars in 13". This
cluster has a dark lane down the middle. It is near M 38 and
reminds me of M35 and NGC 2158 somewhat. Sentinel 13"--visible in
11X80, 220X--Bright, pretty large, pretty rich, pretty compressed,
22 stars counted.

NGC 1912 (M 38) Bright, large, not compressed, seen in finder. The
stars are arranged in the Greek letter "Pi". 58 stars counted at
100X. Sentinel 8/10--13" very bright, very large, very rich,
somewhat compressed, very well detached. Easy in 11X80, 10 stars
resolved against fuzzy background. 150X--105 stars counted,
several pairs and triples, going to 220X (8.8mm) shows off approx.
40 mores very faint stars, mag 14 or so, a great view.

Ultimate Star Party, McDonald Obs. S=6, T=8, 36" f/5-- Abell 9 is
near M38 using chart from Megastar; just barely there, held with
averted about 20 percent of the time. Very faint little planetary,
just a gray dot with the 32mm. About 3 times the size of the seeing
disk.

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. Sentinel 13" 7/10--100X pretty
bright, pretty large, irregularly round, brighter middle.
220X--going to higher power really helps, 5 stars involved,
elongated 1.5 X 1 in PA 45. Nice nebula, double star 5 arcmin to
the west, with some nebulosity around it. UHC filter does not help
the contrast, averted vision makes it grow somewhat.

NGC 1960 (M 36) Bright, large, rich and round. Easy in finder,
several double stars are involved, they are all split at 135X.
Sentinel 13" 8/10--bright, large, rich, somewhat compressed, very
well detached. Easy in 11X80, with 6 stars resolved against a fuzzy
background. 150X--51 stars counted, many lovely pairs and triples.

NGC 1985 Pretty faint, small, round, somewhat brighter in the
middle, it is in a rich field at 100X.

NGC 2099 (M 37) Very Bright, large, very rich. Naked eye at my
best sites in the mountains of Arizona, it is obvious in the finder.
This cluster has always seemed a winter version of M 11 to me for
several reasons: it is triangular in shape, there is a bright,
yellow-orange star involved and both clusters are cut into sections
by dark lanes. M 37 is in a very rich section of winter Milky Way
and at 135X in the 13" I have estimated 200 members by counting 50
in one quadrant. This is one of my favorite clusters in the sky.

Eagle Eye 6" f/6 S+T=7 25X--bright, large, very rich, compressed, 25 stars counted. 40X--42 stars counted, a lovely light orange star is easy to see near the center. There are many lovely chains of stars that provide a terrific view.

Sentinel 13" 7/10--11X80, easy, bright, large, elongated 2X1 in PA
0, 150X--obvious cluster, very bright, large, very rich, pretty
compressed. 146 stars counted, many beautiful chains of stars and
dark lanes through the cluster, dark orange star of about 10th mag
on north side, in a dark area. 220X--many faint stars now resolved,
lots of pairs and chains, all broken up by dark lanes.

Ultimate Star Party, McDonald Obs. S=6, T=8, 36" f/5-- M37 32mm; 60
percent of view; 61 stars in NW quadrant, obvious orange star in
center has faint companion above it is light blue; many lovely dark
lanes, WOW.

Binoculars from Vicksburg site 7/10 S+T
8X25--just a fuzzy spot in the Milky Way, not much
10X50--bright, pretty large, much, much brighter middle, so resolution, averted vision makes it grow is size
11X80--2 stars are held steady, another 3 stars wink on and off, averted vision brings out about 12 more. A rich Milky Way field of view.


King 8 pretty faint, pretty large, somewhat compressed. I counted
10 stars in a mottled background at 135X.

B 34 is an easy dark nebula at 60X in a surplus 38mm Erfle with
gives the 13" a one degree field. The dark area is about 1/2 degree
in size and is roundish with several dark lanes winding out of the
field to the west. Raising the magnification does not help the view.

6" f/6 Eagle Eye 7/10 S+T 40X--not obvious dark nebula, round, with medium contrast.

IC 2120 Very faint, small, somewhat elongated. That is with the
UHC filter at 135X. It is just barely seen. The listed magnitude
of 12 is not the visual magnitude, I would estimate 13.5 mag.

IC 2149 Pretty bright, small, little elongated. The central star
comes and goes with the seeing at 270X. The planetary is a greenish
dot elongated 1.5 to 1 east-west.

NGC 2126 pretty bright, pretty large, irregular shape, not
compressed. 22 stars counted in an arrowhead shape at 135X. There
is a 6th mag star on the NE edge of the cluster.

NGC 2192 Faint, pretty small, irregularly round. 14 stars in a
strung out group.

NGC 2281 Pretty bright, pretty large, not compressed, not rich at
100X. A dozen 10th and 11th mag stars with some fainter attendants.

PK 173 -5.1 pretty faint, pretty large, round and not bright in the
middle at 100X with an O III filter. Without filter at 165X I can
pick out 3 stars involved in the planetary. I believe this object
is misplotted on Uranometria. I seen it on the Northwest side of the
double star, not NE as on chart 97.

Double Stars

14 Aur 3 stars in a crooked line at 100X.

Struve 698 nice, wide light yellow and blue pair in a beautiful
field at 100X.

Theta Aur elongated at 100X, split at 165X, white and light blue.

41 Aur White and light yellow pair at 100X. Don't miss 46 Aur in
the same area, a nice yellow-orange variable.

Struve 644 Single star at 100X. At 200X it is constantly notched,
with a clean split in moments of good seeing. It is yellow and
light blue.

5 Aur single at 100X. 200X gives a clean split, yellow and white
with very different magnitudes.

Otto Struve 147 forms a lovely equilateral triangle with yellow star
at the apex and 2 blue stars along the base. Easy at 100X, very
nice triple.

UU Aur is a carbon star which I look at for their nice red or orange
color. This star is a very nice orange in a pretty rich field.

UV Aur is a carbon star paired with a B type giant, the ultimate
red-blue pair. It is a pretty faint pair, but well worth it. At
165X in the 13" this pair is a gorgeous burnt orange and blue, it
exhibits some of the best color I have ever seen in a double star
even though the stars are not bright.
