Your skills: Intermediate (some years)
Date/time of observation: 2004/08/31 - 21:45 EST
Location of site: West Jefferson, Ohio (Lat 40N, Elev 1046)
Site classification: Exurban
Sky darkness: 6 <Limiting magnitude>
Seeing: 4 <1-10 Seeing Scale (10 best)>
Moon presence: Major - gibbous or near object
Instrument: C14, 22mm Nagler
Magnification: 177x, 325x
Filter(s): None
Object(s): IC 4997
Category: Planetary nebula.
Class: 
Constellation: SGE
Data: mag 11.6  size 2 arcmin
Position: RA 20:20.2  DEC 16:45:
Description:
Very small, circular, almost stellar planetary nebula. In the eyepiece at 177x it was clearly a planetary with a light blue green cast. The nearly full moon was rising but did not interfere with my view. It was more difficult to see with direct vision, but by using averted vision it was very easy to pop it into view. This object was surprising easy to see for it's size and small diameter. Jumping to 325x did not improve the image or reveal any additional structure.

Data: mag 13  size 6 arcsec
Position: RA 22:24  DEC 50:58
Description:
Very small faint but easily detected. There is a hint of an elongation to the north but the may be due to a very dim star located near the edge of the nebula (not the central star). Power didn't seem to help much, averted version was the key, although small it was definitely non-stellar.

Jeff, I run a Website and email list for deep-sky observers,
called the "IAAC": the whole idea is that there ISN'T any one
number (Vmag, Bmag, surface brightness, isophote sizes - nor
your Limiting Magnitude, Telescopic LM, seeing rating, etc.)
which really tells you whether a particular object SHOULD be
visible, nor what it will look like ("how well" you see it),
nor how BEST to see it (with a UHC, OIII, H-beta, no filter,
what magnification, aperture, what conditions, etc.)!
  http://www.visualdeepsky.org

Instead, the best guide to what YOU might see (and the best
way to challenge yourself to see more, without just getting
overly frustrated) - the best way to judge that, is by what
OTHER observers have actually seen!


So for example, if you go onto the IAAC search page:
  http://www.visualdeepsky.org/search.html

and you search for the common name "Rosette", you will see
that it consists of a complex of individual NGC objects,
including open cluster NGC 2244, and several "pieces" of
nebulosity (NGC 2237, NGC 2238, NGC 2239, NGC 2246), plus
still more possibly "involved" objects within a 1o radius.

The result of this search is also a nice list of actual
observations - from people all over the Web who chose to
contribute their observations to the IAAC (among them,
Sue French, Martin Baur, Michael Geldorp, and me!)

Notice that several people made attempts to see the Rosette
with similar apertures to yours and NO filter - and some also
with smaller apertures than you and an H-beta or other filter.

It is indeed a tricky one to see - so you might guess that it
would be very dependent on conditions, including the altitude
of the object above your horizon, moonlight, light pollution,
etc. Note in particular, that someone DID see the nebulosity
(including structure!) from a "rural" site, with an 8" scope
using medium to high power, both with and without an OIII:
 http://www.visualdeepsky.org/logs/msg03130.html


I hope this helps answer your question, Jeff. And by the way,
if YOU would like to share your observing logs for this or any
other object - whether they're successful or not - we would
certainly welcome them on the IAAC! Just drop me an email, if
you would like to join the list or just contribute a few logs.

Clear skies!
Lew

Hey, thats great.  There is a lot of info there!

Please put me on the list.  I just put a digital voice recorder in my 
equipment case to make this sort of thing easier.

Thanks!

Observer: Natko Bajic, Matea Puljic
Your skills: Intermediate (some years), Beginner( <
one year)
Date/time of observation: July, 17th/18th, 2004.
Location of site: Konjevrate, near Sibenik, Croatia
(Lat 44, Elev 225m)
Site classification: Rural
Sky darkness: 6.6 <Limiting magnitude>
Seeing: 9.5 <1-10 Seeing Scale (10 best)>
Moon presence: None - moon not in sky
Instrument: 8" Homemade Dobson reflector, f/6
Magnification: 50x
Filter(s): None
Object(s): NGC 6822 (Barnard's Galaxy)
Category: Galaxy
Class: Irr
Constellation: Sgr
Data: mag 8.8  size 20' x 10'
Position: RA 19h 45m  DEC -14? 48'
Description:
After several attempts with 120mm refractor, this
night I tried to dig up this LSB with 8" reflector. At
50x I have found a very faint glow elongated in E-W
direction, while listed direction is more to N-S. But,
obviously, that was Barnard's galaxy, actually just
its central part. It was quite large, but notably
smaller than listed, with very little central
brightening noted just by me. To other observer it
seemed completely uniform, with edges fading out
slowly. I was trying to locate its diffuse nebulae,
but they were not visible, entire galaxy was very
faint. Unfortunately, we didn't had acess to UHC
filter. Sketch is available at mentioned URL.

Description:
A faint round nebulous patch of uniform appearance.  There is no detectable
brightening toward the core.  A faint field star is located approx. 5' off
the SW edge.  Visible with averted vision at 80x, it began to fade into the
background with increased magnification and could only be fleetingly seen
during moments of steady seeing at 133x.  NGC6487 is paired with NGC6486
but at 15th magnitude, NGC6486 could not be seen.

Description:
At 25x all three could be seen in 1?40' fov. M31 was almost as wide as fov. M110 was hardest to see of all three.
M31 had a bright central region with fainter outer regions slowly fainting into oblivion :) No trace of NGC 206 (a bright emission nebula in the galaxy) or dustlanes seen.
M32 was very prominent. Next to a star that is almost equally bright as M32, the difference was very obvious. M32 clearly was a fuzzy ball.
M110 was faintly visible in between some faint stars. Much more extended than M32 but also much fainter.

This is one of the easiest globular clusters to see with you're naked eye,
maybe becouse the bright star close to it contributes to that (6.7 or something
like that). It's an small star that looks a bit "hairy". I couldn't resolve
the globular from that star. I surprised myself to see in the same time M2 and M15...

Location of site: Catahoula Lake, LA (Lat 31 28 49, Elev 60')
Site classification: Rural
Sky darkness: 6.0 <Limiting magnitude>
Seeing: II <I-V Seeing Scale (I best)>
Moon presence: None - moon not in sky
Instrument: 14.5" f4.5 TeleKit Dobsonian
Magnification: 111, 185, 248, 354
Filter(s): None
Object(s): NGC 6210
Category: Planetary nebula.
Class: 
Constellation: Her
Data: mag 9.3  size 16"
Position: RA 16:44  DEC 23:48
Description:
Although I was able to see a 6.0 magnitude star just outside 
the Keystone (almost overhead), it was not that transparent 
further down. Most naked eye stars disappeared below about 
15 degrees altitude in most directions. There was a pretty 
fair amount of haze, plus the leftover remnants of some cirrus.
The cirrus eventually cleared for the most part, but the haze 
did not, and some dust was raised later as well.

TeleVue Panoptic 15mm, 111x :
Easy to find, clearly non-stellar and blue

TeleVue Nagler 9mm, 185x :
Very blue disk, no surface detail, but traces of a ring structure
were barely visible. 

Meade Ultra Wide Angle 6.7mm, 248x and 
Meade Ultra Wide Angle 4.7mm, 354x :
Oblong in a roughly E-W orientation; still a hint of ring structure,
but no more detail than at 185x (although that's probably due to the
sky conditions). There's possibly a larger, roughly round, envelope 
around it that appears about 4 times the diameter of the disk itself.

Location of site: Kansas City, Missouri (Lat , Elev )
Site classification: Urban
Sky darkness: 3 <Limiting magnitude>
Seeing: 3 <1-10 Seeing Scale (10 best)>
Moon presence: None - moon not in sky
Instrument: Celestron C11 (f/10) SCT
Magnification: 17mm Nagler Type 4
Filter(s): None
Object(s): NGC 6884
Category: Planetary nebula.
Class: 
Constellation: Cyg
Data: mag 12.6 (P)  size 6"
Position: RA 20:10  DEC 46:27
Description:
Surprisingly easy to detect as non-stellar, considering the listed photo magnitude and small size of the PN. The object is about 36 minutes from Omega1 Cygnii in PA 62. It appears as a small non-stellar disc. No details can be seen in the envelope. The edges are fuzzy (poor seeing tonight). The PN exhibits the slightest hint of blue. No trace of a central star.

Overall this is a fine area for urban observers, including the colorful Omega 1 & 2 combo, this PN, and several handsome carbon stars (SV and U Cygni). Be sure to visit NGC 6826, the Blinking Planetary, while you're in the area -- one of the finest planetaries in the night sky for urban visual observers.

actually 244 degrees or thereabouts -- I reversed it in my description.

Object(s): PK64+5.1, Campbell's Star
Category: Planetary nebula.
Class: 
Constellation: Cyg
Data: mag 11,3v  size 8"
Position: RA :  DEC :
Description:
Despite a 10d moon I decided to hunt a few bright planetaries as the sky was 
extremely clear. I started with PK64+5.1 and was impressed.
At 131x the object was clearly non-stellar, bright and very red. At 244x I 
could see the brighter 10mag central star surrounded by a fainter red disk. The 
star did appear almost colorless, the nebula though was deep red. Phantastic!
At 342x the planetary's disk did show signs of a ring structure but, the seeing 
was not good enough to confirm that. Maybe I was just an optical effect due to 
the high brightness of the central star.
At 342x the color was not as intense as at lower power but still very strong.
Very interesting object unlike any other planetary I know.

Data: mag 8,4magv  size 15"
Position: RA :  DEC :
Description:
At 342x this planetary shows a very strange shape. The brighter center is 
almost rectangular and divided into 2 lobes. This rectangle extends about 
10x15? NW-SE. There is a very bright spot in the WNW corner of the brighter 
lobe. This spot looks almost like a dislocated central star. The opposite lobe 
is not as bright but clearly divided by a dark center from the bright NW part. 
The bright inner part of 7027 is surrounded by a faint round halo that 
stretches out some 5+ arc seconds. The halo is visible only with averted 
vision. The color of NGC 7027 is very strong green-blue.NGC7027 is another 
bright PN that is easily observed under a moonlit sky. Beautiful!

These two messages appeared on [amastro] yesterday. NGC 6946, by the
way, is that lovely little spiral on the Cygnus/Cepheus border, that
is also RIGHT NEXT to (40' NE of) a pretty open cluster, NGC 6939...

So that's three fine sights in one field, for modest amateur scopes!

Clear skies and happy SN hunting,

According to vsnet it's the eighth supernova in NGC 6949:

[vsnet-alert 8328] SN 2004et in NGC 6946 (mag 12.8, CBET 95)
SN2004et ?20040927.0 ?128C ?SMr

# SN 2004et (20:35:25.4, +60:07:17.6 (J2000.0), offset about 250"E and
# 120"S) is hosted by NGC 6946, a quite nearby (5.1Mpc) face-on spiral
# (SAB(rs)cd) galaxy in the northern part of the constellation Cygnus.
# NGC 6946 is one of the most SN productive galaxies (SNe 1917A,
# 1939C, 1948B, 1968D, 1969P, 1980K and 2002hh), then SN 2004et is the
# eighth SN in one galaxy (new record!). ?The Asiago team took a
# high-resolution spectrum on Sept. 28, which suggests that it is a
# young type II SN, affected some reddening by both in our Galaxy and
# in NGC 6946; total amount of E(B-V) is estimated as 0.41 mag. ?The
# discovery magnitude is consistent with the expected maximum for
# typical SN II. ?Further observations are strongly encouraged.

I've made a plot from Guide here:

I'm going out just this minute to observe it.
