Sadr? Nope, couldn't be happier.

Okay, you can stop throwing the rotten tomatoes now, the joke wasn't that bad.

Anyway, last night I managed to get a little observing time in and I noticed that Uranometria showed a collection of doubles in the vicinity of Gamma Cygni, Sadr, so I turned the scope in that direction and pulled out the following.

STF 2666: A very tight pair of white stars with magnitudes 6.5 & 8.5. I managed to split the pair at x100, with a separation of just 2.5 this was close to the limit fo what I could split. The primary is listed as a hot O9 star showing a faint blue colour.
STT 206: This is a wide and easily split pair of white stars with magnitudes of 7 & 8.5
STF 2668: Lying close to STT 206 this tight pair were a challenge due to their varied magnitudes, 7 & 9, x100, the highest mag. I can go was just able to separate them, 3.3 is tight. Another white pair
STF 2708: A different colour contrast here, faint orange and white, wide at 34 7th & 9th magnitudes and x56 was enough to split them.
HIP 101062: Faint orange and white again, close at 4, but because they are magnitudes 8 & 8.5 the split was easily achieved at x100.
STF 2705: A more intense orange this time, bordering on the red, very tight at 3.1, yet again because of the closeness in magnitudes, 7 & 8, x100 easily separated the pair. A nice colour contrast.
STF 2700: Deep orange and white, very wide at 23, and a cinch at x56. 6.5 & 8.5 mags.
STF 2702: 8.5 magnitude stars ensure that this tight, 3.3, pair could be split at x100, proving again that a similarity in magnitudes makes the split so much easier. White pair.
Gamma Cygni: Finishing up with Sadr itself. Here there is a vast difference in magnitudes between the white pair, 2nd & 10th, what makes this split possible is the separation of 142. x56 was enough to show the companion, knowing the PA, 196, also helped as there are other faint stars in the field.

A chilly night last night, but it was just great to be out again.

Thanks for your time.

It seems that you had a great time.
Have to do get rid of AP bug and do an observing night as all the EP I have just sitting and collecting dust at the moment

Good report Paul.

Viewing binaries is something I've only got into in the last month or so. Your post will be of great interest for me when I can get back out.

As far as I am concerned, you are the double star man, Paul. Perhaps Mike Casey could lay claim to matching you. Brilliant list, Paul. I have only bothered with Sadr in times past.

Wait- when I said "binaries" I really meant "doubles". Yeah? Yeah? No. I'll get by beginners guide to astronomy again.

First page: 'You live on a planet. When it's night time and there are no clouds, you can see bright things in the sky. Do you know what they are? No? Ok, I'll teach you...'

Calm down, calm down (to be said in a Liverpool accent). Binaries and doubles, there's no difference.
