13.1" f/5.6 unless noted

NGC 2298 Pretty bright, pretty large, much brighter in the middle, 5 stars are resolved at 200X. This globular grows with averted vision. It was easy in the 11 X 80 finder.

Granite Wash Mt. S=7 T=9 13" 100X-obviously a glob.
150X--bright, pretty large, irregularly round, gradually pretty much brighter middle. 7 stars resolved.

NGC 2310 Very faint, pretty small, elongated 2X1 in PA 45 and little brighter in the middle at 100X. This galaxy is tough to observe and higher powers make it disappear.

NGC 2396 Pretty faint, large, not compressed, 16 stars of mags 11 to 13 with an orange star near the center at 100X.

NGC 2401 Pretty bright, small, much compressed, not rich, 7 stars at 200X. There is a pretty bright glow with superimposed stars.

NGC 2409 Pretty faint, small, 8 stars counted at 135X. There are two pretty bright stars, approximately 9th mag and 6 other stars of mags 11 to 13 in this small asterism.

NGC 2414 Bright, pretty large, not compressed, 22 stars counted at 100X. This cluster consisted of three star chains and an unresolved hazy background.

NGC 2421 Pretty bright, pretty large, pretty rich, somewhat compressed, 28 stars of mags 11 and dimmer counted at 135X.

NGC 2422 (M 47) Very bright, very large, not compressed, scattered group with several bright stars of 8th magnitude and more to fill in the background, 44 stars counted at 100X. This nice cluster is an easy, obvious cluster in the 11 X 80 finder, there are several stars resolved and a lovely orange star, KQ Puppi, is about 30 arcmin west of the cluster at low power.Struve 1121 is a double star near the center of M-47, it is a mag 7/7.5 pair, sep 7", it is easily split at 100X. On an 8/10 night during the Messier Marathon, the 13" resolved 85 stars from mags 8 on down. This great cluster shows a bizarre round section in the center with NO stars, strange to see some many cluster stars and none in the center, even on an excellent night.

RFT 6" f/6 very large, pretty rich, not compressed, 24 stars counted with 38mm EP. A wide, dark lane separates the 2 lines of stars. With the 14mm EP 38 stars are counted and William Herschel's description of "st L & S" for "stars large and small" is obvious. This cluster is indeed a mix of stars magnitudes 8 and 9 then a jump to stars of 11th mag and fainter.

NGC 2423 Large, pretty bright, pretty rich, pretty compressed, 33 stars counted at 100X. Nice binary star in the center with both components a lovely dark yellow.

NGC 2425 Pretty bright, pretty small, somewhat compressed, this cluster is elongated 2X1 in PA 0. At 220X there are 11 stars and a haze of unresolved background stars.

NGC 2427 Extremely faint, pretty small, very little brighter in the middle, suspect elongation 2X1 in PA 90. Going to 165X helps the contrast somewhat.

NGC 2432 Pretty bright, pretty large, somewhat compressed, 26 stars counted at 135X. This cluster is much elongated (3X1) in PA 0. Averted vision will add in many faint stars within the cluster region.

NGC 2437 (M 46) Very bright, very large, rich, somewhat compressed, I estimated 140 stars by counting 35 stars in the northeast quadrant. The cluster in obvious in the 11X80 finder and can be seen naked eye at most of the observing sites in Arizona.

Sentinel 13" 7/10--11X80 immediately obvious, 4 stars resolved, a smooth cluster, 150X--very bright, very large, compressed, round, 116 stars counted, many beautiful chains. Planetary on north edge is obvious, light green with central star.

RFT 6" f/6 Sun Valley 7/10 S+T Both M 46 and M 47 fit in the same field of view with 38mm Giant Erfle EP. Even at this very low power (30X), M 46 shows up like a rich grouping with many pretty faint stars. Using the 14mm EP resolves 68 stars in a very bright, very large, compressed and very rich cluster.
The planetary is obvious at the edge of this round grouping.

NGC 2438 Bright, large, elongated 1.2 X 1 in PA 75, the central star is easy at 100X. Raising the power to 440X brings out several dimmer stars involved in the nebula. Also at the higher power the shape of the planetary is seen to be an incomplete ring, somewhat like a horseshoe. This bright rim is about 270 degrees around and is dimmest on the north side. I have always seen this planetary nebula as light green in color. This is from a great night at Sentinel, 7/10 seeing and 10/10 transparency.

Ultimate Star Party, McDonald Obs., Oct. 95, S=7, T=9, 25" f/5--

NGC 2438 the planetary in Puppis 25" 12mm; light green, 3 stars, 2 obvious, one tougher, annular, central section light grey, two layers of nebulosity surround the central star.


NGC 2439 Bright, large, pretty rich, 42 stars counted at 100X. The center of this cluster is dark and this bizarre absorption from dark nebulae makes the cluster take on a horseshoe or "Arc de Triumph" shape.

NGC 2440 Bright, pretty large, much brighter in the middle, elongated 3X1 in PA 30 at 270X. The central star will become stellar in moments of good seeing but most of the time it is just a bright area in the center of this planetary. Averted vision will about double the size of the nebula. It was immediately
recognized as non-stellar at 100X. This nebula is a nice lime green at all powers. Sentinel 13" 8/10--100X, found easily, pretty bright, pretty large, elongated 1.5 X 1 in PA 45, 220X--pretty suddenly much brighter middle, edges fuzzy, not well defined central bright spot is never stellar. 330X--amazing detail in bright central section, looks turbulent, several bright areas interconnected, averted vision makes it elongate.

Sentinel 13" S+T=7 My 50th birthday! 100X-obviously a planetary nebula, to the east is a nice orange star and a delicate triple. 330X--pretty bright, pretty small, somewhat brighter middle, elongated 1.8X1 in PA 60. Dark marking with averted vision in the center. Averted vision doubles its size.

NGC 2447 (M 93) Bright, large, rich, somewhat compressed, 59 stars of mags 9 to 13 counted at 100X. This cluster is triangularly shaped. This wedge shape is elongated 3X1 in PA 90. An unusual feature of M-93 is that there are few stars in the middle, this "black hole" effect can be seen in all the observations I have ever made of this cluster. It is easy in 11X80 and elongated with 4 stars resolved, even in the finderscope.

White Tanks 7/10S+T 6" f/6 Just barely naked eye, about 10% of the time. 22mm Panoptic 28 stars counted, bright, pretty large, rich, somewhat compressed with a wedge- shaped center. Going to the 14mm brings out a few fainter members.

NGC 2451 Bright, very, very large, scattered. 36 stars counted at 60X, with one yellow 4th mag and 35 others mags 7 to 11. 10 stars are resolved in the 11 X 80 finder.

NGC 2452 Bright, pretty large, bright middle, round at 270X. This planetary was immediately recognized as non-stellar at 135X. The central bright section was never stellar at any power. The nebula was a light green color. It is located on the south side of the open cluster NGC 2453.

NGC 2453 Pretty bright, pretty small, pretty compressed, not rich. I counted 17 stars, one of 10th mag and the others from 11 to 13. The 10th mag star is a nice dark yellow at 135X. This cluster was just seen in the 11X80 finder.

NGC 2455 Pretty bright, pretty large, pretty rich, somewhat compressed, 26 stars of mags 11 to 13 counted at 100X.

NGC 2467 Bright, pretty large, pretty rich, 31 stars counted at 100X. This cluster was easy in the 11X80 finder. The star cluster is very nice and would generate observers if it where alone, but there is some bright nebulosity associated with this cluster. The nebula was seen without the UHC filter to start, but adding the filter made the nebula much better. There is a bright, round spot of nebulosity on the southwest side of the cluster and several pretty bright streaks on the northeast sections. Covering my head with a dark cloth and using the UHC filter, I could see that the entire field of view was nebulous to some degree. To top is off, there are several dark lanes winding there way through this region.
Take a look at this little known cluster and nebula.

Sentinel 7/10 S+T 13" 100X pretty faint, pretty large, resolved into stars 10m.... 14 stars counted many pretty faint, in a triangular cluster. The nebula is pretty bright, pretty large, round with one star involved. There is more considerably large nebulosity in an elongated streamer to the east of the cluster. 150X--nice magnification, it all fits.

cluster--19 stars counted, several very faint, about all that the 13" will show. The nebulosity has one 8th mag star and 2 of 10 mag, 6 more stars are 11m..... There is a hint of dark lane with averted vision. Adding the UHC filter really increases the contrast and brings out some very faint detail within the elongated nebulosity. Going to 220X with no filter brings out several thin, dark lanes within the
round nebula.

NGC 2477 Bright, large, very, very rich, very compressed. 180 total members estimated by counting 45 stars in the northeast quadrant at 100X. There are many lovely dark lanes that wind there way through several star chains and an ever-present glowing background of more stars. There are two round dark markings in the cluster on the south side and nice, wide double star on the north edge. I can resolve 20 stars in the 11X80 finder.

13" Sentinel 8/10 S+T 11X80 bright, very large, round, suddenly brighter middle.
60X--60 stars resolved very bright, very large, very rich, compressed. The are 2 round dark markings in the cluster on the south side. A nice wide double star is on the north edge.
100X--I estimate 180 stars by counting 45 in the NW quadrant.
A great view, still an obvious cluster with LOTS of members.
Both 150X and 220X don't show fainter stars, but the close pairs of double stars in the cluster are being split and at 220X the cluster over-fills the field of view in the scope.

Salome Canal 6" f/6 S=6 T=7 New SAC site, possibly.
38mm Giant Erfle 4 stars resolved on top of large fuzzy spot.
22mm Panoptic 14 stars counted very bright, very large, very rich, pretty compressed, stars 10m.... Some dark lanes on south side and beautiful chain of stars on NE side.
8.8mm best view for resolving stars, but better as cluster at lower power. 28 stars counted, nice matched double star about 11th mag. on north side. Dark lanes more prominent.


NGC 2479 Pretty bright, pretty large, pretty rich, somewhat compressed, 10 stars of mags 11 and 12 with many faint background stars at 100X.

NGC 2489 Bright, pretty large, pretty rich, not compressed, 31 stars in nice chains counted at 100X. Seen in 11X80 finder.

NGC 2509 Bright, pretty large, pretty rich, compressed, 39 stars of mags 10 to 13 counted at 100X. This cluster can just be seen in the 11X80 finder.

NGC 2525 Pretty faint, pretty small, round, little brighter in the middle at 135X.

NGC 2527 Bright, very large, pretty rich, somewhat compressed, 36 stars of mags 9 to 13 fill the field with nice chains at 100X.

NGC 2533 Pretty bright, pretty large, compressed at 135X. There is one star of 9th mag and 15 more of mags 12 to 13, then a fuzzy background of unresolved stars.

NGC 2539 Bright, large, rich, elongated 2X1, 65 stars of mags 10 to 13 counted at 100X. This little compressed cluster has a double star of 10th mag just west of the center. It is just seen as a fuzzy spot in the finderscope. 19 PUP is on the south side of this cluster. It is a wide triple star, easy at 100X and yellow with two white comes.

RFT 6" f/6 bright, large, somewhat compressed and rich. With 14mm EP I counted 60 stars with a beautiful blue-gold double star 19 Puppis on the south edge. A fuzzball in 10X50 binocs.

NGC 2546 Very bright, very large, scattered, not rich, not compressed. 62 stars counted at 60X, one is a lovely dark yellow star on the south side of the cluster. This large cluster is easy in the 11X80 finder.

NGC 2567 Pretty bright, pretty large, pretty rich, 42 stars counted at 135X. There are several nice, curved chains of stars within this cluster.

NGC 2568 Faint, pretty small, not rich, somewhat compressed, 6 stars at 150X, 2 about 11th mag and 4 of 13th mag.

NGC 2571 Pretty bright, pretty large, pretty rich, somewhat compressed, 30 stars of mags 9 to 13 counted at 135X.

NGC 2579 This object is a cluster with nebulosity. The cluster is pretty faint, large, irregularly round with lots of dim members. There where 21 stars counted at 135X. The nebula is pretty bright, pretty small, elongated 2X1 in PA 90, it is brighter on the east side. The UHC filter will enhance the contrast of the nebula.

NGC 2580 Pretty bright, pretty large, rich, somewhat compressed, 26 stars of mags 11 and lower counted at 135X. This irregularly round cluster has a very fuzzy background of stars.

NGC 2587 Pretty faint, pretty small, somewhat compressed, 16 stars counted against a fuzzy background at 135X.

NGC 2588 Pretty faint, small, somewhat compressed, 19 stars of mags 12 and lower counted at 135X.

Non-NGC objects

Be 135 Faint, pretty large, elongated 3X1 in PA 45 at 100X.
There are several stars involved in this nebula. Dark nebulae near this object make the surrounding field star poor.

Bo 4 Pretty bright, pretty large, somewhat compressed, 22 stars counted at 135X.

Bo 5 7 stars counted at 100X. This small asterism has one orange star and 6 white stars in a horseshoe shape.

Bo 6 15 stars of mags 11 and less counted at 135X.

Bo 15 Faint, pretty small, not rich, compressed at 165X. There are six stars in this cluster, including a 9th mag star on the east side. The cluster has a fuzzy background. High power helps this compact cluster, it was barely noticed at 100X.

Cr 135 Very bright, very, very large, not compressed, scattered cluster of 38 stars in a 40 minute field. I needed to use my 38mm Erfle eyepiece, which gives a one degree field of view to get this entire cluster in the 13". There is a nice, wide blue and gold pair involved.

Cr 185 Pretty faint, pretty small, not compressed, not rich, 18 stars counted at 135X.

Czernik 29 Pretty faint, pretty large, not rich, not compressed, 18 stars of mags 11 and less counted at 135X.

Haffner 10 Only 6 stars of 12th mag at 135X. Not much.

Haffner 15 Pretty bright, pretty small, very compressed, not rich at 165X. Faint fuzzy background of unresolved stars at all powers.

Haffner 16 Pretty bright, small, pretty rich, very compressed at 165X. 19 stars counted with one of 11th mag and the rest 12 and below. This very compact cluster is in a rich field.

Haffner 20 Faint, pretty small, compressed, 6 stars of mags 12 and dimmer, with a hazy background at 135X.

Mel 66 Pretty bright, large, pretty rich, irregularly round, 27 stars of magnitudes 10 and dimmer counted at 100X. There is a nice background of unresolved stars and the cluster has several lovely curved chains of stars.

Mel 71 Bright, pretty large, much compressed, much brighter in the middle at 100X. I counted 48 stars from mags 10 to 14 all as a foreground to a fuzzy backdrop. Seen in the 11X80 finder.

PK248-8.1 (M4-2) Faint, small, round and not brighter in the middle. I suspected this dim nebula at 100X, it was held steady at 220X. Averted vision makes this light grey dot grow in size.
13" 220X Faint, small, round, not brighter in middle, held steady at 220X, just seen at 100X.

Ru 21 Pretty bright, pretty large, pretty rich, somewhat compressed, 23 stars of mags 11 and dimmer counted at 165X.

Ru 24 6 stars of mags 11 and less counted at 135X.

Ru 27 Faint, pretty large, elongated 2X1 PA 90, 14 stars of mags 12 and less counted at 100X.

Ru 32 Pretty bright, pretty large, not rich, not compressed, 21 stars counted at 135X. There is one star of about 9th mag and then the main grouping is magnitudes 11 and dimmer.

Ru 36 Faint, pretty large, not rich, not compressed, 10 stars superimposed on a fuzzy background at 135X. Placing Omicron PUP out of the field of view helps the contrast of this cluster.

Ru 43 Pretty faint, pretty small, somewhat compressed, 10 stars and a haze at 100X.

Ru 44 Bright, large, rich, 52 stars counted at 100X. This cluster was easy in the 11X80 finder.

Ru 45 Pretty bright, pretty large, rich, not compressed at 100X. I counted 8 stars of mags 11 to 13 and a bright glow of unresolved dim members. This cluster does not stand out, it is in a rich Milky Way field.

Ru 151 Pretty faint, pretty small, 10 stars of mags 11 and less counted at 135X.

Sharpless 2-302 Very faint, pretty large, round, no clear edge to this nebula. It takes 100X and the UHC filter from a great site to pick out this tough nebulosity.

Sharpless 2-307 Very faint, pretty large, elongated 1.5 X 1, not brighter in the middle. This nebula is just a very faint fog at 100X with the UHC filter. I could not see it without the UHC filter installed.

Tr 6 Pretty faint, pretty large, somewhat rich, somewhat compressed. 16 stars and a fuzzy background at 100X.

Tr 7 Pretty faint, pretty small, not rich, somewhat compressed, 17 stars counted at 135X.
