The soap Bubble Nebula discovered in 2007 by an amateur astronomer, Dave Jurasevich on Mount Wilson Observatory on a clear night when low cloud had rolled in obscuring the Los Angelos light pollution. This is a faint but lovely etheral subject so took on this 'interesting' challenge from my home town in wet and windy south-west England. A total of almost 700 5 min. frames ) taken in SHO (57 hours total integration time).

Equipment used:

12" GSO RC telescope on EQ8-R Pro mount. Stellarmate image capture software running on a Raspberry Pi 5 controlling 6 devices including ASI 2600 MM Pro camera, ASI Guide camera with ZWO-L OAG, ZWO EFW, ZWO EAF and Pulsar Dome rotator sychronised with mount.

Post processed with Pixinsight. Still working on colour variations whilst trying not to over cook it.

Not found any scientific papers on this PN yet and would be interested to know if anyone else knows of relavent papers? Wiki mentions it is thought to be between 4,000 and 5,000 lt yrs distant. With a pixel scale of 0.32"/pixel and width measured on the image of 255" N/S and 240" E/W, this gives it a size of 5.5 to 5.2 lt yrs. Close inspection of the bubble shows a faint but distinct blue star close to its center. It would be fun to find out if this is the star responsible for the bubble and according to Wikipedia it has a J band mag of 19.45.  Will publish a close up as well.
