NGC 6992 - Veil Nebula (eastern part)

The veil nebula is an SNR in the constellation Cygnus. It is part of a supernova remnant, with NGC 6960 and NGC 6995 being the other two parts [1].  Due to the bright moon that night not a too good picture, so it will be revisited.

M39 - NGC 7092

M39 is an open cluster in the Constellation Cygnus. It seems disputed, who discovered this open cluster. Bruce et al. state that Charles Messier (re-)discovered the object in 1764 [1]. They say rediscovered, as J.E. Groe claims, it was discovered in 325 BC by Aristotle[2]. This is also the information obtainable at the website of the NGCIC project. It is large, but very loose as well. See a rather brilliant object on Wikisky.org [3]

Moon

Well, again our moon, this time decrescent. However, it was the reason for the short exposure times before :)





 Object Name:

NGC 7023 - Iris Nebula

The Iris nebula is quite an impressive sight. Bright with a nebulosity, which seems to "eat" the surrounding stars. It was discovered by W.F. Herschel in 1794 [1].

 

 Object Name:
 NGC 7023 - Iris nebula
 Object Type:
 open cluster with nebulosity
 Object Position:
 RA 21h01m36s DE+68°10' 1''
 Location/Date/Time:
 St. Pölten, 15.8.2009, 22:38 MESZ (15.8.2009 20:38 UTC)
 Parameters:
 7 x 300 s - ISO 1600

 

NGC 6910

The nebulosity, where the clusters lies in (IC 1318) is not visible at this picture (not even with strong low pass filtering). This open cluster, which was discovered by F.W. Herschel in 1786 [1], lies in the constellation Cygnus. Have a look at Mr. Bachmayers image, who has most likely the most wonderful picture of this region.
 

 


 Object Name:
 NGC 6910
 Object Type:
 open cluster
 Object Position:
 RA 20h18m06s DE+49°40' 13''
 Location/Date/Time:
 St. Pölten, 16.8.2009, 00:14 MESZ (15.8.2009 22:14 UTC)
 Parameters:
 4 x 300 s - ISO 1600   
 
A strongly color enhanced detail of the cluster gives you an idea, that there is some nebulosity

NGC 6995 - Veil nebula (SE Part)

NGC 6995 is the third part of the super nova remnant called veil nebula. See the other parts and description here and here..

M52 and Bubble Nebula (NGC 7635)

This beautiful pair is located in the constellation Cassiopeia. M 52 is an open cluster, discovered by Charles messier in 1774[1]. Rather close lies the bubble nebula, which has is name from his very distinctive shape, caused by a strong star wind from the central star [2]. A rather beautiful image can be found here
