Faint Globular near M11?
      #2556896 - 08/02/08 11:01 PM


Hey everyone, last night I ws looking around the area of M11, and since my finder is a little off last night, ( got replacement set screws for the bracket today! ), I was scanning, and saw a very faint patch. I'm surprised I even detected it! Is there any pretty faint small GC's near M11? Also, I can't find the Blue Flash Nebula, Is this impossible for mag 4.5-5 Nude eye skies? Maybe I'll try again tomarrow night or Mon night. Lastly, I've had a problem finding M55. Since this is low in the sky, will it be hard to spot?

The nearest globular to M11 is NGC 6712 (roughly 2.5 degrees south of M11). I have seen this one in my Nexstar 9.25 under magnitude 5 skies on a number of occasions, and it is pretty nice at moderate to high power. It resolves fairly well and has an unusual appearance (elongated with a slightly triangular shape), although its component stars are faint. Clear skies to you.

Here's a trick. Next time you are looking at NGC 6712 at low power move it to the west side of the FOV, Then add that Ultrablock you have to the eyepiece. Less than 1/2 degree to the east is the nice planetary nebula IC 1295. It is almost the same size as the globular cluster. If you are using the 10" scope they will appear almost identical.

There is the globular cluster NGC-6712 in the vicinity of M-11. It's moderately bright but it is a fuzzy patch of light even in my 10-inch unless the skies are dark and clear. However, there is also the faint planetary nebula IC-1295 in the same field of view, so if you find the globular, you'll find the nebula too. On the other hand, NGC-6905 is rather large and faint, therefore you won't see it if the skies are hazy. A nebula filter does help a lot with this object, which appears as a fairly small, circular glow with no obvious central star.

Cool, I'll check that neb out 2nite. When I look for Blue Flash maybe again tonight, should I search with the Ultrablock in, or just normal ep?

An Ultrablock will definitely help. It's the only way for me to find it with my 6-inch Dob from the usual sites I observe from.

In my sky it wasn't an easy find, low in the sky and LP, but persistence paid off.

Start at Ascella, bottom left star of Sagittarius tea pot. At midnight EDT, M55 will be approximately 8.5° to the left.

It will appear as a faint fuzzy with low mag. I barely caught it with my 28mm. With my 8E and averted vision I was able to resolve some stars.

NGC 6905 is easy, even from my skies, it has a strong bluish, greenish color to it, and I can also see the central star steadily in moments of good seeing, the nebula has a mottled look to it, and has a significant central brightening, and under really good conditions, a not quite straight polar cap effect can be glimpsed at high magnification, these being brighter areas of the nebula to the East edge, and a brighter area on the West edge, this nebula is beautiful, and the Northern, and Southern edges of this beauty bulge out, but are fainter, and more diffuse. This nebula is on my favorites list...clear skies...

Actually, there are *two* planetary nebulae near NGC 6712: IC 1295, and Sanduleak 2-374. IC 1295 can be a real toughie, as it is big but rather faint (Vmag 12.5). I don't have any information about the other object, other than its position and magnitude (14.2), although from the DSS image, it appears to be nearly stellar. Clear skies to you.

Well, I saw that tini tiny nebula with the filter in, it was very nice in the 17mm with both objects in the field. I also found M55, it was very big! I got the best view of M17, Trifid, and Lagoon through the 17mm w/filter. I was also looking at M80 and M4, M54, and M69. Even though M54 doesn't resolve, it's neat!:D It resolved in the 17 and 10mm's nice, and was nice in the 6.7mm. I didn't attempt the Blue Flash, but I thought about it. I also have to align the finder, it's a little off.

I got great views of M12 and M10 too. I can say it was the best night of the Summer.

Blue Flash (NGC 6905) is easily visible in a 10". From my notes there is a fairly bright star in FOV (10" @ 64X) to the North of it. A filter is not necessary, but an OIII will enhance the view. It does have a blue tint to it.

I did find M30 last night. Wasn't a good night though, they said clear, and there was always clouds in the sky somewhere. Figures how whenever I have to get up the nextday, it's always a night I can't miss out on-almost every time!

Jake:

NGC 6905 isn't that tough to find if you start from the right location. That would be the diamond asterism in Delphinus. Here is a rough finder chart. The circles are supposed to be 5-degrees, which should apprxomiate your 10x50 finder. (But the circles look a little large to me.)

There is a very distinctive pattern of stars near the object. I marked it with red lines on the finder chart. Here is a closer view of the field.

Stars are shown to 9th mag in the first chart and 10th in the second.

I actually did start from the diamond, and noticed that pattern in the finder, and on Stellarium, it was right near there. I'll try to find it again 2nite or tomarrow night.
