Description:
Pos: 07 21 15 / -18 08 37. Fairly bright PN that responds well to the OIII 
filter. At 342x it appears as a small, round ~10" disk that is brighter towards 
the inner part. The edge is quite clearly defined, though not sharp. The NW 
part of the tiny disk seems to be slightly brighter. I could not see any sign 
of a fainter outer shell, so the diameter of the object given in Uranometria 
does not correspond with my observations. The program Guide 6 gives 10" as the 
figure for the diameter of M1-13. The planetary is located less than 1' N of an 
11mag star. Easy object that was not so easy to find with low magnification (131x).

Armin, just a short note to say "thanks" for your usual
crop of very interesting logs! :)  I have never tried
for either of M1-13 or M3-4 before - and in the case of
M1-13, it looks like I have really missed something.


Also to all loggers, just a short FORMAT NOTE: when you
log an object with multiple important designations like
these two planetaries, put the catalog and id you think
is most important as the primary, and then put all the
others in parentheses after it. Here's an example:

Object(s): PNG 232.4-1.8 (M1-13)

(Also for your convenience, our search engine already
recognizes "M1-" and "M2-" as Minkowski catalog ids.)

That way, you can distinguish a log of one object like
these fine planetaries, from a log of a GROUP of objects,
for example the galaxies in a Hickson group or one of
the various "galaxy -tets" (Stephan's, Seyfert's, etc.)

Clear skies!
Lew Gramer

Ron, "Orion's Collarbone nebula" (my long-winded name for NGC 2022 ;>) is
indeed a pretty little planetary - and very often overlooked by many Winter
deep-sky observers! Below is a log I made of it from a relatively mediocre
site, with a 17.5" almost exactly 6 years ago.

You can find this and several other logs like it on the "Visual Deep Sky
Observers'" site which I maintain:
  http://www.visualdeepsky.org/search.html

And if you do manage to tease out some interesting details on this (or any
other!) object with your 6" refractor, I hope you'll consider contributing them
to our searchable online log - 4700 deep-sky logs, and growing:

Filter(s): None, UHC
Object(s): NGC 2022
Object category: Planetary Nebula.
Object class: 4+2
Constellation: Ori
Object data: mag 12.4 15.20m*  size 28"x27"
Position: 054206.18+090510.3
Description:
Next up on our tour of duty with the 17.5" Club scope tonight, we went off
searching for the unexpected Orion planetary NGC 2022. We star-hopped from the
lovely star triangle (lambda Ori) at the head of Orion, down along the E
"collar bone" of the Hunter. After first encountering emission/reflection
nebula Cederblad 59 accidentally (see previous log this night), we managed to
sweep back to a pair of mag 8 stars, which point conveniently SE to the
planetary. With low power n2022 was distinguishable from surrounding stars, but
hardly striking. No color or detail could be seen. But at higher power with the
UHC filter, the annular nature of 2022 became immediately apparent. In
addition, a definite brightening could be observed near the middle using
averted vision. At the time, after first deciding it was the mag 15 central
star, I noted it on more careful observation to be clearly non-stellar, and in
any case too bright to be the star. I guessed it to be either nebulosity
surrounding the central star, or maybe an incipient inner ring. Now though,
after viewing some of the available data and images, I have to conclude that
this central brightening was in fact either that central star bloated by poor
seeing, or else some bright knot of NGC2022's internal filamentary structure,
which confuses the eye at this power. Other features were also logged at the
time around the bright ring of nebulosity: the most striking was a seemingly
irregular brightening or knot SSW of the center of the object. Another such
knot, slightly less distinct, was noted an equal distance to the N. Between
these two brightenings, I almost got the impression that I was seeing bipolar
lobes, although their shapes and spacing were definitely more irregular than
the symmetry one expects in true bipolarity. Finally a mere suggestion of an
outer halo was noted to increase the overall diameter of the object by maybe
10", with what occasionally seemed to be an irregular longer lobe on the NW.

Moon presence: None - moon not in sky
Instrument: 6" f/8 refractor (Celestron CR-150 HD)

Filter(s): O III
Object(s): NGC 2440
Category: Planetary nebula.
Class: 5 + 3
Constellation: Puppis
Data: mag 11  size 10"
Position: RA 07:42  DEC -18:13'
Description:
A very nice compact Planetary Nebulae that survives light polluted skies.
On this night the seeing and transparency were only fair, though it was calm at
intervals.  Bright enough to be seen without a filter, though better with an
O III.  No more than a swollen star at low power, magnification is needed to get
resolution.  Though listed as being up to an arc minute in size, only 10" or so
of the core is visible at first.

At high power its a smeary but viable double knot. To make sure that what I
was seeing was true, I tried to determine the orientation of the knots to an
8th magnitude field star east of the nebula.  This I did.  In time, I also
picked out an egg-shaped haze surrounding the core and extending the size
of the nebula. The haze points roughly, but not quite directly, to the
field star.  While the long axis of the haze ran approx. East - West, the
knots stacked one over the other North - South.  The nebula is classified
5 + 3, irregular form, irregular disk, and now I can see why.

Being a bit whimsical, I like to call this object the "Burning Ember" since
it glows small and bright even in my light polluted skies, and I know it is
supposed to contain the hottest central star of any known Planetary.  Given
the amount of detail NGC 2440 reveals even under modest conditions with a
6" refractor, it is really quite a remarkable object.

Interesting news for our Southern observers: this should make

(again?) suddenly popped into view! Has nice size, outer edges well defined,
 best seen w/avereted vision, ghostly appearance near transparent, no details,
 but amazed at how obvious it was this night. Eyes glued to the scope tried to 
see more but ecstatic to at last capture this one. Stars near steady, very 
clear. Should have used more powers but a very cold morning ! Skys better than 
normal, near rural site but have scattered lights from school and apartments 
nearby.

Constellation: Sagittarius
Data: mag 4.6  size 90' X 40'
Position: RA 18:04  DEC -24:23'
Description:
>From my light polluted site all I see at first is the brightest part of M8, a
sphere of light, next to a bright star cluster NGC 6530.  In time I can make out
two stars imbedded within the sphere, and a bright section at the south-west
part of the globe.  Across from this is a fainter bar of light separated by a
dark gulf.  It is this gulf which gave M8 its name, the Lagoon Nebula, although
as O'Meara and Burnham point out it is much more of a channel than a "lagoon".

Under dark skies I saw much nebulosity around both the sphere and the star
cluster, but not so in Lombard even when switching to a 12" dob.  Surprisingly,
the refractor gave me the better view of this object from my comprimised
location, well enough to see how it got its name.

The star cluster adds beauty to the whole view.  Through my star diagonal I see
2 stars at the base of the cluster, a square of 4 stars above that, a line of 3
stars at a 45 degree angle to the top right corner of the box, then a small
triangle above the whole group at the top.  To the left of this cluster the
glowing sphere, the faint bar, and the dark gulf between-  a beautiful sight
the light pollution could not rob me of, thanks to the UHC filter and some
patience at the eyepiece.
