Another very popular target, but one I've not visited with my telescope for 5 year, the Bubble nebula region.

Listed in the Sharpless Catalogue as region SH 162, but more typically known as Caldwell 11 or NGC 7635, the Bubble Nebula is created from the stellar wind from the large young star in the middle. The whole structure is embedded in a huge HII region which makes for a very dramatic setting.

Any exposure looks good on the Bubble Nebula - this isn't anybody's best. It is quite soft and I was mainly just testing stuff at the time, but it presents nicely.
