Distance (l.y.): 257, Luminosity (Suns): 23.3
Observed colors:  W, B 

Observations: Observed at 112x.  Easy.  yW and W this pass. 
Just N lies a very nice curved arc of four brightish stars (around 9-10m), with the pair just to the NNW of 3 Peg being a nice double— ~10" @ 340, both 10m.  (It is cataloged as OS 443.)
Webb saw them as W and pB.

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: 3 <1-5; 1 best>
At the moment of observation this double was almost in the south. The PA of 349° gave it a almost exactly vertical orientation. In this case the special orientation added to the view. 3 Peg is a pleasing double for a small telescope, the stars are bright, the separation is a bit large (39") but not too large. Best view is with 20x. A is white and B seemed to have a "dirty" yellowish hue, but that could be due to the sky-condition.

3 Peg was also split with the bino, but needed an absolute steady moment. The bino observation was very short, the stars were already disappearing again in the clouds.
3 Peg forms a funny (yes, another one) asterism with three fieldstars which form an almost straight sloping line above and sideways of the double. It looks like the roof of a shelter that protects the beatiful double from interstellar duststorms or other threats from deepspace...

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

Easy split of a wide double at 100X. Magnitudes of the two components seem closer than those listed. Primary white, secondary tint of blue.

My first report after moving my house,I am in the beautiful ambience of Dias de Luna. After struggling around Epsilon Pegasi I found my way through the stars. Very clearly split, a fine doubles for big bnoculars. Typical ambience of Spirit of 33, many dogs
barking in the night, nobody stops them

Pretty one; slight magnitude difference noted. I saw the primary as greenish. Had some difficulty with the color of the secondary; it almost seemed to have a pinkish color.

White, Bluish (yellowish?) Having a difficult time with the colors here. Very nice equal white pair in field (OE 443).

Seeing: 7 <1-10 Seeing Scale (10 best)>
Location of site: Killeen, Texas, USA
Site classification: Suburban.
Sky darkness: 4 <Limiting magnitude>
Telescope: Celestron-8
Eyepieces: 25mm, 10mm, CMG
Magnification: 80x, 200x, 165x
A wide spaced pair, both appearing blue. There is about 1 mag difference between the 2. There is a bent line of stars to the north, with a second pair located at the vertex of this line, to which 3 points.

I estimated the separation of this pair at about 10' and the PA at about 345d, by comparison with 3. I latter used Cartes de Ciel to ID the star as STT 443, mag: 9.47/9.67, sep/PA 8.2"/348d. As to 3 itself, I got a sep of 39.8" and a PA of 349.8d (ave of 5 meas.)

This is a refreshingly wide double in a small naked-eye threesome with Peg 4 and 7, which could mark the eye of the equine.

Comments: The primary star is Whitish blue and the secondary a Bluish white. The delightful pair is set in a bow-shaped crown of stars in the north of the field.

Transparency: 7 <1-10 Seeing Scale (10 best)>
Location of site: Charminster, Bournemouth, Dorset
51ºN, 1ºW
Site classification: Suburban
Sky darkness: 4.3 <Limiting magnitude>
Moon: 4 Days Old, but below horizon
Bootle Scale: 8 (Suburban/Urban)
Telescope: 8" Meade LX-90 SCT f/10 (Lucy)
Eyepieces: 30mm Celestron Ultima (67x), 
26mm Meade Super Plossl (77x), 
12.5mm Celestron Ultima (160x), 
2x Barlow
Magnification used: 67x
 
Wide at 67x. Primary star is slightly brighter than its companion. As with Struve 2804, the colours are white and blue-white. However, the field both stars are in is spectacular. At 67x, the view is magnificent. There is a curved line of four almost-equally spaced 9th 
and 10th magnitude stars nearby, giving an effect like the head of Scorpius, with Struve 2804 and its companion playing the part of Antares and Sigma Scorpii. Magnificent! This star is definitely going into the memory of the Autostar.

Seeing: 5-6 <1-10 Seeing Scale (10 best)>
Location of site: Northwich, Cheshire. UK.
53° 15' N -2º 33' W
Site classification: Suburban
Conditions: Clear sky in patches of drifting cloud.
Moon(1st Quarter)
Sky darkness: 3.0 ( UMi ) <Limiting magnitude>
Telescope: 200mm f/6 Newtonian reflector mounted over a Vixen GP mount (manual slow motion).
Eyepieces: 20mm plossl and 9mm orthoscopic.
Magnification: X60, X133.
 
Using a magnification of X60 gave a very nice view of this double star located in the centre of a very busy field.
 
A magnification of X134 showed a white primary with a pale yellow companion.  There was an intriguing faint double star nearby (north preceding) with almost the same PA.
