Observing Report (UHC with 6" F5)

I went outside and setup the  StarHOC 6" F5 Newtonian on CG-5 (old model
with aluminum legs). Now that the moon’s out of the way for a few hours it
was time for some early evening star gazing.

First up, Jupiter. Still light outside and there wasn’t any point looking at
anything else except the first star I could find to dial in the collimation.
Made out the equatorial belts and temperate zones with minor banding north
and south. Checking the Juplet Java applet after the fact I see that the GRS
was in transit, but I didn’t see it in the eyepiece. Magnifications: 120x
and 166x; Filters tried: Celestron Polarizing and Blue 80A. The polarizing
filter was worthwhile when the sky was still light, but as it darkened I
pulled it and tried the blue. The blue actually helped with the contrast of
the north and south temperate zones, as well as darkening up the equatorial
belts. No more detail was visible, but there was an overall contrast
improvement on the large features.

Next up, M22, a favorite, as are the other large globulars. There are many
small globulars that are better served by larger apertures and higher
powers, but the likes of M22 and M13 are easy targets in a 6" scope at both
60x and 120x even in mag 5 skies.

Since the sky was now as dark as it was going to get, I moved on to M8, the
Lagoon Nebula. Visible as a bright patch against the gray light polluted
background, it was time to put the UHC to the test in a 6" scope. There was
no disappointment with the filter. Swapping back and forth between 60x
unfiltered and 42x filtered, there was no doubt that the UHC made the nebula
appear _much_ brighter against the background sky.

From there I moved up to M20, the Trifid Nebula with the UHC in place at
42x. A much harder target to see under the conditions than M8, but still
made visible with the UHC where it was virtually invisible without. Averted
vision helped of course with the filter in place, and hinted at the dark
lanes that give the Trifid its signature look.

On to M17, again better with filter than without. Clearly visible as both
it’s namesakes Check Mark Nebula and Swan Nebula. This object has a dark
"spot" that stands out as an obvious patch darker than the background sky
and the nebulous cloud, which is what makes the nebula appear to have a
swan’s neck.

The next object is one that I’ve never had much success with, M16, the Eagle
Nebula. However, my observing skill appears to continue to improve as this
object using averted vision with the UHC was clearly nebulous around the
open cluster with which it is intermingled. No Eagle was visible, nor any
detail really. Just the nebulosity around the open cluster.

As promised in the other post on filters, Cygnus was now in a prime position
for an attempt at the Veil. Moving the UHC from the 18mm eyepiece to the
30mm to increase the field of view, the western portion of the Veil (The
Cirrus Nebula) that passes nearby star 52 Cygni was invisible without the
filter and obvious with, even without averted vision. It didn’t take much
searching around for the eastern portion of the Veil (The Network Nebula) to
pop into view with the filter in place. I forgot to check for this portion
of the nebula without the filter, but for sure the filter made the western
portion appear where it was otherwise not visible.

After that I swung the scope around to the west and took a long look at M13,
but first I wanted to see if I could find M5. I was successful, but as I
stated previously this is one of the small globulars that benefits from a
large aperture and higer power. Then it was back to M22 while it was clear
of the tree tops, finishing up with the Wild Duck cluster M11.

All in all a great night and reaffirmation that a 6" F5 Newtonian is a fun
and capable scope, and that a couple hours of observing is a great way to
spend an evening.

Obs: Jupiter & Lambda Oph.

After a month or more of smokey and/or cloudy skies I decided to
attempt an observation and sketch of Jupiter earlier this evening.
Ripples were always present around the limb of the planet due to poor
seeing conditions.  Nevertheless I was able to complete a rough sketch
and upload it to my blog.

At 138x Jupiter’s North Equatorial Belt appeared to have a reddish
brown color.  That was the only noticeable color seen with the 13cm
refractor.  Io was near the planet’s north-following limb.  A little
later in the evening Io was seen in transit.  The planet’s following
limb appeared shaded a bit more than its preceding limb — a phase
effect.  A Moon-SkyGlow filter improved the view a little for this
twilight observation.

After the Jupiter observation I did some "sight seeing" and eventually
landed on Lambda Ophiuchi.  The A & B pair were split at 218x with a
narrow gap between the two stars.  A #82A Light Blue filter improved
the view a bit under the relatively poor seeing conditions.  The "A"
star appeared yellow or yellow-orange while the "B" star appeared
bluish in color.

Has Anybody Observed:

1) Stuff in Baade’s Window. Last night a friend (his 9.25" SCT) and I
checked out two globs which I believe are in Baade’s Window, ngc6522 and
ngc6528. "Where is M13" (btw a great program – get it if you haven’t
already) shows them as being very close to the galactic core, and I figure
that they are visible because of the window. Anybody observe anything else
in Baade’s Window, or know anything interesting about it?

2) Stuff in M24. My younger son is always seeing patterns/asterisms, and he
has named one of them in M24 the "Goat Head". M24 is very rich in
interesting star chains/patterns, and we enjoy noodling around in it. Also
in M24 are B93 and B92, which form the eyes of the horse’s head which is
what a lot of folks see as the overall shape of this star cloud. However, I
have always been most fascinated by ngc6603, and primarily because of what I
can’t see. It is framed by some dark nebulosity, and the stars in this
cluster are just at the edge of resolvability in our scopes. It is a fuzzy
patch, but with averted vision one can start to make out shapes/structure. I
looked through a lot of big scopes at Stellafane, and how I wish I had
gotten one of them to point at this object instead of the ubiquitous
Dumbbell Nebula (I was so sick of it). Anyway, I have always enjoyed
ngc6603. Anybody ever get a good/resolved look at it? Anybody observe
anything else in M24. or have anything interesting to say about it or Star
Clouds in general?

3) Finally, we tried to observe the star cloud ngc206 in M31, but failed due
to the Moon being just below the horizon. My sons and I have observed this
in our homemade 10" f/6 (pretty easy) and our 6" f/8 (harder, averted
vision). What we see is a lighter patch in the galaxy, which is easier to
see if the scope is moved a little bit. Even in the 10", I don’t think I
would notice it if I didn’t know where to look. I like this object because
it gives me something to look at IN M31, and not just the overall galaxy (as
nice as it is). The other thing we have done is compare the dust lanes that
we see with those in an image, and figure out which dust lanes are which,
and try and follow them. Anybody else have any observations of ngc206, or
about Star Clouds in general? How about other things to observe in/about

BTW, my younger son and I are going to give a talk at our club’s next
meeting including observing this stuff, and so anything folks can contribute
will be a help to us.

Need 2" adaptor for focuser

Hi all..

Anyone know where I can get a 2"
adapter for the 2" focuser that Meade put of their
old DS series ? I have the 1 1/4" one, but
nothing else. Even my T rings will not fit
the threads at the top of the draw tube.

If I have to, I will get another focuser,
but this one is fairly well made, and
*could* be usable with 2" EP’s with the right

New scope here

Sorry for any rain Fri, or Sat, but Fri. I picked up
a Meade DS 10 (vintage 1987) that has been very well
kept, and maintained ! I am now the fifth owner,
and from the paperwork the original owner got this
from Co 7 :) Very clean primary, and secondary. Came with
Meade 9×60 finder scope with .96 diag, and EP with
helical focusing. Nice clear and sharp finder.
The previous owner lubed all the mount bearings,
and in general tweaked this scope as much as it could be,
and it shows ! It moves as easily or more so than most
Dob’s out there. Drive works well also.

First light was Sat, and it was already well colliminated
and ready to go after a little under an hour
of cool down. Just looked at the usual suspects
in the MW, and Jupiter, and the Moon. M 16, just
looked *cleaner* and brighter than I’ve seen in a
long time.

I was surprised at the nice contrast views, and how
it snaps into focus. I love the FOV !!!!!

Except for not having the 2" focuser adapter I
have nothing to complain about.

This is my first journey into the fast newt world,
and I am loving it !

Climatology and astronomy

In this era where there is a pressing need to explain global climate
and the seasons,the belief that the Earth’s axial and orbital motion
correspond to ‘sidereal time’ make productive work impossible –……

For all the mathematicians  who would willingly  create fiction to
support the idea that the natural noon cycles are 24 hours exactly in
order to explain the 3 minute 56 second difference by using the
orbital motion of the Earth there may be genuine astronomers who are
responsible enough to see where the imaginative ‘sidereal time’ view
is a genuine curse for this modern era.

For all the mathematicians who make contrived and silly  statements
about astronomy and climate  while having no feel for the astronomical
material,how many genuine people could easily pick up on the exciting
and productive avenues which distinguish global climate from the
seasons via an astronomical treatment –

The main component in global climate and the oscillation of those
temperature bands depend on how long a given location spends in direct
solar radiation or in the orbital shadow of the Earth.A mathematician
might not understand  but it is crucial to recognise the actual main
component in global climate and hemispherical seasons arises from the
orbital motion of the Earth and not a pseudo-dynamic of variable axial

WEEKEND METEORS: On Saturday morning, September 1st…

Space Weather News for Aug. 30, 2007

WEEKEND METEORS:  On Saturday morning, September 1st, a flurry of bright and colorful meteors might come streaming out
of the constellation Auriga.  The source of the shower is ancient Comet Kiess, which has laid down a trail of debris
that Earth will cross this weekend.

But will a shower really materialize?  Forecasters are divided. Some expect a brief but beautiful display rivaling the
Perseids.  Others say the debris stream is too empty for significant fireworks.  Either way, the peak is due around 4:30
a.m. PDT (11:30 UT) on Saturday morning.  This timing strongly favors sky watchers in Hawaii and western parts of North
America all the way from Mexico to California to Alaska.

Spaceweather’s full coverage of the Aurigid meteor shower begins Friday, Aug. 31, with links to live audio from a meteor
radar, which will monitor activity throughout the weekend. Sky maps and more information are available now at
