ADS 15268
Position:  2144+0953  Rating:  4
Components:
 A:  2.4m, K2 II
 B:  12.66m, 82” @ 323 - 
 C:  8.85m, 144 +” @ 319 - 
Year of last AB Measure:  1990
Observed colors:  D!, ?, W

Observations: C8:  Observed at 104x.  C was easy, but B was difficult.  I had to switch to 280x and get A out fo the FOV to see B. 
C11: Observed at 112x.  On this observing pass, I noted D!!, ?, and B!.  The B star was very difficult, being sandwiched between the two brighter stars.   Great colors on A and C!
Webb saw yW, ?, and B.  He mentioned that this pair had the "pendulum effect" at meridian.

Notes: AB 1879:  82 @ 325.  AC 1874:  140 @ 322.
The primary may be variable.

Star: Epsilon Pegasi
Date & Time: Sep 5, 2001; 22.15 
Seeing: 4 <1-10 Seeing Scale (10 best)>
Location of site: Annen, The Netherlands
53 N, 6 E
Site classification: Village-backyard 
Sky darkness: Varying with the clouds 
Telescope: Swarovski AT80, 80mm f/6 spottingscope
Binoculars: Leica Trinovid 10x42 
Magnification: 10x, 20x, 60x
Harshaw Scale: 4, 5 <1-5; 1 best>
The deep-yellow color of A is immediately and with all mag's noticed. At the moment of observation the Moon was very low in the East, rising between some houses and trees. It was striking that the color of Epsilon A was exactly the same as the color of the Moon. A quarter of an hour later the Moon was higher and far less yellow. 

B is rather faint but could be seen easily with the Swarovski. With the bino it was necessary to keep it very carefully steady, handheld but resting on the Swarovski. B was visible at the short moments when there was no cirrus passing and when I was able to keep the bino absolutely steady.

With two more stars around Epsilon A and C form a Cygnuslike figure. A is "Deneb", the next brightest star is Albireo. The figure is not as nicely symmetrical as Cygnus itself, but "Deneb" is shifted somewhat to the NW.

Despite this funny asterism and the beautiful yellow color of A I could only give this double a rating 4 on the Harshaw-scale, and even a 5 for the bino:
Rating: 4 (spottingscope), 5 (bino)

Star: Epsilon Pegasi
Date & Time: 6 Sept 2001 ( 22:00 UT)
Seeing: 4+ <1-10 Seeing Scale (10 best)>
Location of site: Barreras, Salamanca, Spain.
Site classification: Rural, Suburban.
Conditions: moon 3 days past full , fairly dry but with gusts of wind.
Sky darkness: 3+ <Limiting magnitude> much light due to moon
Telescope: Meade 8" SCT mounted on a Losmandy GM8.
Eyepieces: 20mm plossl, Celestron Microquide
Magnification: 100X, 400X 
Harshaw Scale: 4 <1-5; 1 best>
This is a really wide double, so wide at 142.5" it would be better with binoculars. 
I thought I had never measured a wide double with the Microquide so I mounted it on the scope with the 2.5X powermate. I made three measurements and arrived at an average of 142.8" distance and a angle of 319.3º which is in good agreement with our list.

Star: Epsilon Pegasi (A-C)
Date & Time: 8th September 2001. 2125UT
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
Components A and C are very wide with primary showing an attractive yellow and the  'C' star a less defined blue. I did not see the 'B' star. Moving the bright primary out of the field may have helped in this regard. I should have tried.

Location of site: Sena de Luna, Leon, Spain

Telescope: Vixen 20x100 bincoulars 
Magnification: 20x
After having a 1st contact with Epsilon Peg, I went to observe and report 3 Peg. Going from 3 to Epsilon it's easier to find the companion of Epsilon, knowing it's about 30 deg clockwise and 3 times the sep of 3 Peg.

This double is difficult because of the big magnitude difference and the wide separation, it's easy to get lost without a reference. The conpanion should be 0.1 mag dimmer respect to the companion of 3 Peg, but it seems much fainter - probably because the main star is so brighter.

Despite the good limiting magnitude of the site, it's not so easy to pick the 2nd component.

Bootle Scale: 7 
Telescope: Meade LX-90
Eyepiece: 30mm Celestron Ultima
Magnification: 67x
 
Wide, wide at 67x. The primary is much brighter than the secondary. The primary had a strong orange tinge.

The observation was taken on a hazy night at Holt Heath, which is 
common land about 10 miles north of Bournemouth, but definitely still 
in the 'Suburban' category as it's only about a couple of miles from 
the nearest town (Wimborne Minster). It was very hazy and there were 
cloud banks repeatedly going overhead.

This is Enif , the nose of the animal.
    
Comments: I observed a rich Yellow star with a wide Bluish/Violet companion. Good object for small scopes.
