98x. Colors of
white,
blue, undetermined, adn white (?). Rating of 3E. The C and D stars are difficult, even in good skies. In tonights mush, they were very difficult indeed and seemed, at times, like the Cheshire Cat-- there, then not, then there again. "I wish you wouldn't keep appearing and vanishing so suddenly; you make one quite giddy!" "All right," said the Cat; and this time it vanished quite slowly, beginning with the end of the tail, and ending with the grin, which remained some time after the rest of it had gone. "Well! I've often seen a cat without a grin," thought Alice; "but a grin without a cat! It's the most curious thing I ever saw in all my life!" 'Twas brillig, and the slithy toves Did gyre and gimble in the wabe; All mimsy were the borogoves, And the mome raths outgrabe." James Kaler's "Star Notes" web page has a nice writeup on this star. Check it out. Polaris and the bright companion are at least 2,000 AU apart

There was a light breeze. Relative humidity was about 68% Sky darkness: --- <Limiting magnitude> Telescope: Discovery DHQ 8" dobsonian Eyepieces: 1.25" Plössls - 25mm, 15mm, 10mm, 6mm Magnification: 49x, 81x, 122x, 203x |
I always like looking at
this
double. Although I could easily find the faint companion at 49x, the
best view was at 81x. At this magnification, the primary is
yellow-shite and the companion is pale blue. It reminded me of what the
Earth and Sun might look like from perhaps a moon of Saturn.

Have viewed and
measured
this
guy a couple dozen times simply because this is my setup star for the
Bigdog 17
to align the finders and focus everything etc. Well, I have never
gotten the
WDS measure for this one, but that was listed 30 years ago and
precession has
probably caused the PA to change due to Polaris passing so close to the
pole. Measured
18.54 sec at 222 deg PA.![]() Processed my
Polaris data from
the 13 May observations to see if the very faint C and D listed
companions
could be located. Two stars were found, but the C star is a mystery.
The WDS
lists AC at 43 sec 88 deg PA in 1884 and then 0.1 sec 281deg PA in
1939. I
located a star that seems to agree with the 1884 observation at 39.5
sec 089.5
deg PA. Maybe the 1939 data is faulty. The D star is somewhat displaced
too,
but the last observation was in 1890 at 82.8 at 170 deg PA, I measure
83.13 sec
at 181.9 deg PA. I will try again, as this is my Bigdog alignment star
and viewed quite often.

This night is
“first-light” for the Giro-II mount in
Sena de Luna. Certainly, it’s a pleasure to set-up the telescope in
less than 5
minutes. Without the list of doubles for the project nor maps of the
sky, I
only can find Polaris. As usually, it’s an easy
split at low magnifications
and both Naglers offer splendid views, but seeing is seeing, and I
remember the
split was more clear using a Televue Ranger at 48x on a night with
Seeing and
Transparency = 10 than tonight with the Takahashi. It’s what I repeat
night
after night: the most important part of the optics in a telescope is
the
atmosphere! This
night was also the “Neat Comet” night. Loveley
view in the Tak with a 35mm Eudiascopic at 23x and with the 16mm
Nagler. The
wonderful thing was the fact that the Neat comet was in the same field
of view of
M44, producing an unforgettable sight. Interestingly the best view was
obtained
with a pair of 8x40 Pentax binoculars that perfectly framed the event. |

Old reliable. Like
several
others here, I always use it for one of my alignment stars, so I see a lot of it! Both Polaris and its little buddy have always looked white to me, with the primary maybe having a slight bluish tinge. 50x, 106x. Ambience: No real ambience, although things got a bit exciting when the dog needed to come out and managed to get her long leash wrapped around the rocker box. That's pretty much the extent of our suburban wildlife!

Alpha UMi, Polaris Date & Time: 16/17 May 2004 00:45UT Seeing: 7 <1-10 Seeing Scale (10 best)> Transparency: Location of site: Northwich, Cheshire. UK (53° 15' N -2º 33' W) Site classification: Suburban Conditions: Nice and clear. Sky darkness: 4.3 UMi <Limiting magnitude> Telescope: 200mm f/6 Newtonian reflector. Mount: Vixen GP. Eyepieces: 18mm Orthoscopic, 9mm Orthoscopic, 6mm Orthoscopic(x2 barlow) Magnification: X67, X133, X200(X400) |
Polaris must be one of my
most
observed doubles as I often use this star to fine-tune the collimation
of my
Newtonian reflector. On this occasion, Polaris was as wonderful as
always with
it's tiny companion clearly in view at all magnifications used. The
best view
was using the 18mm orthoscopic where the companion appeared as a sky
blue colour against
the pale yellow colour of Polaris. I never get tired of observing
Polaris.
However, I quite soon get tired of trying to keep my Newtonian
reflector in
perfect collimation.

An easy split in low
power. The
primary is yellow and the fainter secondary perhaps is blue. to compare what I could do with the smaller aperture. I didn't make the split until I got to the 17mm, however, I then went back to the 25mm and got it.
