Subject: Field Report - Cygnus and Ophiuchus Sent: Friday, July 13, 2001 5:58:53 From: email@example.com (Ed Mosser) Thursday July 12th was a great night for observing. The unseasonably cool weather continued and the skys were crisp. It was about 60 degrees when I ventured out with the ETX at 10:15. I started in Cygnus at the middle star of the cross, Sadr. This is one rich area of the sky. Sadr is a wonderful 2nd mag star set in a field of Milky Way stars. Most of the surrounding stars are 8th mag and up. NGC 6910 was easily located about 50' north and west of Sadr. I counted about 14 stars with 4 8th mag stars forming a "Y" on its side. CR419 is 1 degree west of Sadr and is located around a 6th mag star. The individual stars are difficult to resolve, but there is a glow to the area. M29 - is fairly easy to locate, but disappointing. It is 2 degrees south and east of Sadr and forms a central box with arcs going off the two top stars. There is a double star in the same FOV just south of M 29 with stars about 9th and 10th mag. BE86 is 1 degree west of M29 and gives off a hazy glow. Hard to resolve, but I knew it was there. It is about 8' with about 4 9th - 10th mag providing bare minimum light for my conditions. I4996 is a 8 -10 ' open cluster with 6 8th to 10 mag stars forming a cross. Look for a 8th/9th mag double about 15' north. I then claimed a new cluster which I have named "Ed's bowl" It is about 70' south of I4996 and consists of 9 stars shaped in an arc which forms a bowl. The last star, 29 Cygnus, is the brightest, a 6th mag,. It is a pretty neat grouping of stars. NGC6871 was a nice bright open cluster. After viewing all the dim obscure clusters, it was nice to see a fairly bright one. It is about 20' in size, anchored by a 7th mag star at the north edge. I counted 25 stars and there were two double stars in the center of the cluster. The north double was both 8th mag. and the south double was 9th/10th mag. My son yelled out at me and came out to join me. He had a couple of oatmeal snack cakes (Little Debbie brand) and I showed him Mars. After 15 minutes of great conversation, he headed back in and I turned to Ophiuchus. I used Sue French's excellent column "Small Scope Sampler" in August Sky and Telescope as my guide. I think Sue has the best thing going in the small scope world other than Mike's website. Her main scope is a 4.1 inch refractor, so her observations are similar to what we can see. I4665 - there are about 35 stars visable in a loosely structured 1 degree open cluster. It contains mainy 7th 8th mag stars. 61 OPH is a nice double of 7th mag stars with sep about 15" The PA is eithe 90 or 270 degrees, based on which one is the primary. CR350 is a large open cluster with several 8th 9th mag stars. Nothing spectacular. 67 OPH is a 3m/7m double star with sep 45" angle 140 degrees or so. 70 OPH is "real nice" couldnt resolve at first at 48x but easy at 96x. The 5th/7th mag double is tight (4") at150 degrees. Back to 48x and I could see a bump. Starhopped to NGC6633 - "Oh yes" The best OC of the night. Big and bright. Go see this one. It runs NE to SW with a 6m star to the SE of the cluster. I counted 45 -50 stars with many in the 7th - 8th mag range. "This is good stuff." I4756 - another keeper. This is large about 1 degree with lots of 8th - 10th mag stars. Not as bright as NGC 6633 but really a special open cluster. It was hard to count but I estimated about 60 stars in this fine cluster. NGC6572 - well, I can't confirm this one. But, I think I saw it. There is a zig zag of stars about one degree west. I then moved back east and located two stars, 9th and 10 mag, about 10 arc minutes west and 5 arc minutes south I saw something. Was that it? At 12:25 I came back in and had a chicken salad sandwitch on homemade bread, with a glass of cold milk. I reviewed the notes and nodded in satisfaction. It just doesn't get much better than tonight.
