There’s that other arm up there holding the club.

First, though, a minor housekeeping measure. I was able to pry it a bit further apart with an 8mm Radian (148x) — at least when it would hold still. Stellar Classification: F6 Stellar Classification:  A0. The WDS lists the secondary magnitudes at 11.3 (Pi-3) and 10.14 (H VI 83).

Those two blurred into one star when I was looking at them, possibly because of the haze, or perhaps because the sky gods were playing tricks on my eyes in return for calling Orion’s shield a bow.

Position Angle:  253°  (WDS 2010)

A search for "60mm" will find all doubles where we used that size telescope. E42 - More Efficient Testing on Automotive Development, Improving the Accuracy of Fuel Consumption Measurement, Readout No.

Chi 2 Orionis (Chi 2 Ori / χ 2 Orionis / χ 2 Ori) / k aɪ. This site uses Akismet to reduce spam. And look at it! And the arm attached to that shoulder is the one that’s holding that  …. In order, from Pi-1 (π-1)through Pi-6 (π-6), they are A0, A1, F6, B2, B2, and K2.

Omicron (ο) Cephei, Σ 2883 (STF 2883), and Σ 2923 (STF 2923). It’s stretched out across fourteen degrees of sky in north to south declination! The Cambridge Double Star Atlas, on the other hand, has them at 8.8 and 8.7.

The class D (for Degenerate) is the modern classification used for white dwarfs – low-mass stars that are no longer undergoing nuclear fusion and have shrunk to planetary size, slowly cooling down. Post was not sent - check your email addresses! Click on the chart for a larger view). Recently, the National Institute of Standards and Technology has developed Reference Materials of gold nanoparticles that are nominally 10, 30, and 60 nm. As particle size decreases, surface area increases as a function of total volume.

Here again, though, there are discrepancies.

But it was easy to see in a 60mm f/13.3 using a 20mm TV Plossl (40x). Change ). At the other end of the scale, it requires a medium size scope to be spotted. The surface chemistry can be changed by any number of means including Because of this red dwarf companion, the likelihood of habitable planets in this system is low.

CHI-2 ORI (Chi-2 Orionis). Milk is an example where homogenization is used to reduce droplet size to delay the onset of phase separation (i.e., creaming with the fat rising to the surface). I thought I had a glimpse of it with a 12mm Brandon (98x), but a 10mm Radian (118x) did the trick. (The stars in that list are in order of right ascension, which is at the extreme right).

And to what does a name like H VI 83 refer, you ask? Use this form to contact our specialists. E14 - Masao HORIBA Awards"Measurement of Bioparticles" and "Measurement of Internal Combustion", Readout No. (Stellarium image with labels added, click on the image for a larger view). U Orionis - is a long period Mira type variable that changes between magnitudes +4.8 and +12.6 over a period of 372.4 days. And don’t forget to click on the chart for a larger view. The particle size of the dispersed phase typically ranges from 1 nanometer to 1 micrometer. Position Angle:  5°  (WDS 2002) We’re going to imitate a tight-rope walker and edge out along that line now, so stare straight ahead and don’t look down — there’s nothing below you but dark nothingness. Now that said, I like your Pi in the sky and it’s better for me than what’s on the table. RA: 5h 10.0m   Dec: +08° 10′ RA: 04h 49.8m   Dec: +06° 58′ If you have excellent seeing and a lot of aperture (fifteen inches?) I especially like that last pair – Σ627. And I had no problem seeing the H VI 83 secondary in the 60mm scope, so that argues against it being a challenging magnitude of 10.14. (You can see why a shield just doesn’t work here!). RA: 04h 54.9m   Dec: +10° 09′ The zeta potential of any dispersion is influenced by the surface chemistry.

E07 - Products and Technologies of Jobin Yvon HORIBA Group, Readout No. At its brightest, it's visible to the naked eye and easily seen with binoculars. So it appears the Cambridge Double Star Atlas has it wrong and the WDS has it right. The first time I saw these, I barely got a glimpse of them before they disappeared behind a stand of trees to the southwest of my observing sight. As you can see in the photo, there is a star to the north that is a possible candidate, as well as a pair of fainter stars to the southeast. Chi 1 Orionis (χ 1 Ori, χ 1 Orionis) is a star about 28 light years away.

Examples of colloidal dispersions include solid/liquid (suspensions), liquid/liquid (emulsions), and gas/liquid (foams). Separation:  21.2″ The next stop is a real gem — actually, a pair of gems — Pi number three and it’s very close neighbor, H VI 83.

But I only have one variety in the house — cold and old.

(Stellarium screen image with labels added), Σ 630  (A-BC is H III 52)            HIP: 23419    SAO: 112340 It looks more like a bow, as in bow and arrow. The primary is a pleasing orangish red, and the secondary — well, let’s just say you’ll be doing good to see it, period. This link takes you to a companion site whose goal is to help you learn the night sky one bright star at a time. (STScI photo, click to enlarge). And that would be darned heavy as well, but it would tend to shield you. Castor – three steps to take you from aw to awe! Particle Interactions . Scientists working to improve colloidal stability measure particle size, zeta potential, or both. I was using a Meade AR-5 with an 18mm Radian (66x) that gave me a field of view of about nine-tenths of a degree and scooped both of them out of the sky with no problem. At any rate, the one you want is lingering over there to the southwest, and is not difficult to see — and I wouldn’t begin to hazard a guess as to color because it was just too faint.

RA: 5h 02.0m   Dec: +01° 37′ You can’t miss them. A spectrally classified star becomes a wealth of information. It is in the constellation Orion, where it can be seen in the tip of the Hunter's upraised club.. χ 1 Ori is a G0V star. Magnitudes: 6.6, 7.0

Stabilization serves to protect colloids from aggregation and/or phase separation. I wasn’t aware of the discrepancies at the time I looked at these two stars, but I would be very surprised if Pi-3’s secondary could be seen at all in the glare of the primary if it actually has a magnitude of 11.3. Spectral Classification:  B9, B9.

a change in the pH, salt concentration, surfactant concentration, and other formulation options. Now you can call Pi-3 (π-3) by that name, or by 1-Orionis, or by STT 560, or by Tabit — it answers to all four names. pH affects the zeta potential of a dispersion. If you look at the last chart above, you’ll see that Σ 627 is at the point of a triangle which it forms with Pi-6 (π-6) and Pi-5 (π-5), both of which make up the base. ( Log Out /  ), I think it’s time for the real thing. Commercial suspensions may be formulated to keep particles in suspension without sedimenting to the bottom. What I noticed immediately, though, was two bluish-white dots of almost identical brightness. “cloak.” , Filed under: 4.

Class D is further divided into spectral types DA, DB, DC, DO, DQ, DX, and DZ. χ1 Ori is a G0V star. Change ), You are commenting using your Google account. The primary of this one is an eye-catching blue-white, and the slightly dimmer secondary appears to me to have a slight tinge of yellow or red. In my 60mm f/13.3, Pi-3’s secondary was very difficult to see in the 3.2 magnitude glare of the primary, but the H VI 83 secondary was a breeze, thanks to a much dimmer primary magnitude of 7.2. For an excellent source of information on William Herschel and his double star endeavors, take a look at this site. If we’re going to have a late night feast, we need to work up a real appetite.

Finally, on March 7th, I cracked it with the AR-5 under slightly better seeing conditions than previous attempts.
