Addendum 2000-2001


 
Bob Hogeveen
Star: Epsilon Orionis 
Date & Time: December 18, 2000, 23:00 UTC 
Seeing: -- <1-10 Seeing Scale (10 best)>.
Location of site: Annen, The Netherlands (53 N, 6 E)
Site classification: Village-backyard 
Sky darkness: 4.3 <Limiting magnitude>
Conditions: Lot of moisture in the air
Temperature: 0° C
Telescope: Celestron CG-11 
Magnification:  
A very wide and, sorry to say, bit uninteresting double. In the starfield around Epsilon star B is indeed the closest to Epsilon, but there are many more stars nearby and this pair doesn't look in anyway as a double. Funny is that B is first in a row of 3 faint stars, in one line from Epsilon. A bit like the moons of Jupiter (there is another star on the other side of Epsilon in about the same line!). 

The field around Epsilon is nice, mainly because the attractive double Struve 751 in the same FOV, just 14' to the NNW. 
Rating : 5

Transparency: 7/10 
Temperature: 18º 
Other Conditions: Calm. Moon 5 days old 
Location of Site: Terara, New South Wales 
Australia,  S34.52, W150.38 degrees. 
Site Classification: Suburban 
Sky darkness: Northern sky: 5; Southern: 5.5 
Binoculars: 25X100mm Somet Binoculars. 7X35mm  Tento 
HS: 4 
HS= Harshaw Scale1-5 (1 best) 
This very wide double was impossible in small binox because of the glare of the primary. However, the extra power of the 25X100 made it relatively easy. I found the colours White and Bluish.

Double was very near moon. 
primary....yellow 
companion....very dim with no observable color 

Hey we got stars!!!!  Almost a full moon and lots of dew but a clear sky. 

I decided it was good enough to  lug the LX50 out and set it up.  It's been a long time.  Couldn't find where we put the dew shield and the 8x50 finder to keep them away from the grandkids (and the dog) over Christmas.  The batteries in the Telerad were dead and I never did get anything resembling a polar alignment but what the heck...we got stars. 

After I got set up, Orion was doing a nose dive behind the fir grove so I tried to get a quick shot of M42 but the sword was long gone.  So up to the belt to grab epsilon before it to disappeared.  Then I turned my attention to the twins.  I was able to use the UO 7mm ortho with the 8" SCT and spent some time fooling around with the MicroGuide. 
Still not comfortable enough with the MicroGuide to use it to submit reports but if I can get a few evenings fooling with it, I'll be ok. I do use it to check observations though. 

It was wet, really wet.  So wet I finally raided the sock drawer and put the EP's in socks.  The moon was bright enough to read the heavy print at the top of the 33-doubles print outs.  Not really cold, but very still and quiet.  And the Christmas lights were down...now if I could do something about the yard light from hell two lots over.

I thought I might have made the companion tonight, but I wouldn't swear by it. I thought  that I might have seen a faint spot at about the right separation and PA, but it may have been wishful thinking. I kept thinking that mag 10.5 should have been more apparent.

Date & Time: 23rd, January, 2000, 21:50 UT
Site of Observation:  Oviedo, Spain
Site Clasification: Urban
Seeing: 2-3 <1-10 Seeing Scale (10 best)>
Sky darkness: About 3 <Limiting magnitude> 
Transparency: 8-9 
Temperature: About 18ºC 
Conditions: Rather strong wind 
Telescope: Televue Ranger 
Magnification: 30x 
Eye Piece(s): 16mm Televue Nagler 
   
After having Nagler eyepiece's first lights on M42 (Herschel always tried to make first-lights on this beautiful Messier object), I aim the small refractor to the central star in Hunter's belt. 

Aside a wonderful space-walk in the rich field around Alnilam, this double is not very interesting. It's a reallly wide open double and having into account the faint secondary, it even doesn't appear as a double star. It's more an issue of getting the complete belt as a collection of doubles than really enjoying from the split of a double star. Anyway, having Alnilam and Alnitak in the same field of view saves the observation.

I finally found the wide-spaced but dim companion. By fiddling with the RA and DEC slow-motion controls to establish directions, I estimated where the PA would lie and saw a star laying there. It seemed to be quite a bit dimmer than mag 10, however, to 
me. Perhaps some unseen cloudiness was obscuring it? The primary is blue-white, the secondary to faint to tell.
