Star: 1 Pegasi
Date & Time: 4 Sept. 2001 ( 21:00 UT)
Seeing: 4+ <1-10 Seeing Scale (10 best)>
Location of site: Barreras, Salamanca, Spain.
Site classification: Rural, Suburban.
Conditions: almost full moon, fairly dry but with gusts of wind.
Sky darkness: 3+ <Limiting magnitude> due to moon.
Telescope: TeleVue 101 on a Alt Az Gibraltar mount
Eyepieces: 6mm Radian
Magnification: 90X
Harshaw Scale: 3 <1-5; 1 best>
Real big mag difference. had to use adverted vision to 
find the secondary. Primary white with tint of yellow, secondary dim grey.

Ambience: Tues. 4th of Sept., a night of apparent poor seeing looking at the sky while I was setting up the TeleVue 101 on the Gibraltar mount. Also the moon is just past full and is lighting up everything. I had been using the 8"SCT and the 7" MCT very much lately so I decided to warm up the TV 101 which I will bring to the big 2nd reunion in the Sena de la Luna the 14th and 15th of Sept. That afternoon Manolo had put about 20 yearling cattle in a corral just on the other side of the road from our village house so I had a lot of company during the night. As I had thought the seeing was on the poor side about 4 out of 10.

Star: 1 Pegasi
Date & Time: 8th September 2001. 2025UT
Seeing: 3-4 <1-10 Seeing Scale (10 best)>
Location of site: Near Halifax West Yorkshire, England.
Site classification: Suburban
Conditions: Clear sky, fresh NNW'ly breeze
Temperature: 8C 
Sky darkness: 4.8 <Limiting magnitude>
Telescope: Orion Optics UK GX250 10"  f4.8 Newtonian on Vixen GP mount.
Eyepieces: 20mm Plossl
Magnification: x60
The large magnitude difference is the most obvious feature in this wide, easily split double. The primary is obviously yellow and I saw the secondary as the same colour.

The field is quite pleasing,.

Star: 1 Pegasi
Date & Time: Sept. 29, 2001
Seeing: 6-7 <1-10 Seeing Scale (10 best)>
Location of site: Hodges, South Carolina, USA
Site classification: Suburban.
Temperature: 54ºF
Sky darkness: --- <Limiting magnitude>
Telescope: AP 155 F/7 Apochromat
Magnification: ---
Yellow, Purplish with 17mm Nagler and 2X Barlow. Nice.

Ambience: As much as recent events have effected me I did get away from "my 
troubles" last weekend. I made it out to my Roll-off Roof observatory about 8:00 Sat. night Sept 29th. The temp. was 54 degrees F so i didn't have to worry about any snakes hanging out in the Observatory. 

Clean cool night with a near Full moon rising in the East. I got everything out, set up and began observing. I was able to relax and enjoy. I took my time, not worrying about how many doubles I'd get to or how long I'd spend just sitting at the eyepiece "enjoying the 
view". Not worrying or doing too much thinking, just having fun. A very nice evening.

This delightful double is found on the front hoof of our prancing steed. It is easy to locate near with a triplet of stars including Peg 9 and 13 to guide the star- hopper.

Comments: This is a warm Yellow primary with a contrasting faint Bluish companion to the NW. A zig-zag grouping of fainter stars appear south in the field.

Ambience: The garden is alive after Spring rain, with waves of Sweet Peas and the peppery tang of  Carnations. Rose brambles are heavy with heady blossoms and hidden frogs croak all night after endless days of soft showers on lush grasses. Tomatoes are in flower and orange blossoms are falling. As I pack up I realise that Andromeda is up and I find it in binoculars. I lower the eyepiece and see the woolly shape with no detail yet again. I rarely view objects this low. I get the measuring tape and discover the eyepiece is a meter  from the grass. Tonight I might exchange Omega Centauri and 47 Tucan for one last glimpse of Andromeda in all it glorious detail. Might.

Seeing: 6-7 <1-10 Seeing Scale (10 best)>
Location of site: Northwich, Cheshire. UK.
53° 15' N -2º 33' W
Site classification: Suburban
Conditions: Clear spell with drifting high haze.
Sky darkness: 3.0 ( UMi ) <Limiting magnitude>
Telescope: 200mm f/6 Newtonian reflector mounted over a Vixen GP mount (manual slow motion).
Eyepieces: 10mm plossl, 9mm Orthoscopic, Celestron MicroGuide, TeleVue 3.35X Barlow.
Magnification: X120, X133, X322.
1 Peg was one of my Olympic champions in last years project
to celebrate the Olympic games held in Sydney. I have returned to it many times since that date and was glad to see it included for the current
project.

This time, at X120 and X133, 1 Peg gave a stunning view of yellow with a
deep blue companion. This was different from my observation of 1 Peg last
year! when I observed pale blue/purple for the companion.

Not what I expected from a hazy sky. I have read that you can get some
good double star observations through the high haze but didn't expect the
colour contrast to change in such a way. Trick of light maybe!!

Over the two nights I managed to take some measures using the CMG.
The average from 18 measures gave the companion to be 36.4 arcseconds away in position angle 312 deg.

Easy at 67x. The off-white primary is much brighter than the fainter secondary. At 160x, the primary reveals itself to be much more yellow, and the fainter companion in contrast looks blue with a slight greenish tinge.
