The Bubble Nebula and its many friends

[JohnH]

I cannot get the image to show! so here is a link.

This LHaRGB is a total of 4hrs 47mins imaging over two nights and I really felt the benefit of my observatory - no need to set up, take down etc.

Sharpstar 15028 HNT telescope on iOptron CEM25P
Camera ZWO ASI1600MM Pro at -10C
Control ZWO ASIAir Mini.

The area around the Bubble Nebula (C 11) is full of objects:
To the right is M 52 (open cluster)
To the left SH2-157
Just below C11 and SH2_157 is SH2-159
Below SH2-159 is NGC 7538

The "Bubble" is dead centre of the image and is visible if you zoom in (couldn't get it quite as contrasty as I would have liked!).

I still think that the Bubble, together with its neighbours, is the most beautiful DSO.

Possibly the longest imaging time I have managed.

Finally, I have managed to upload the image!!! This is a .jpg, the link above is to a .png which is better quality.

John this is the attachment from Astrobin, not sure why it didn't work for you:

That is a lot lot better than your first process of this target (and friends). 
How did you combine the Ha?

Glad you are happy with having your observatory - at Last!!!!

Hi Carole,

Thanks. My browser just doesn't seem to want me to upload .png files, maybe it is the size. To me the .png has richer colours.

I adopted Roberto's suggestion from my previous image (Cocoon Nebula).

It was all in Pixinsight. I downloaded a script which allowed me to subtract RGB from the Ha, this gave me a starless Ha image which I added to a starless RGB colour image which I then added to my RGB star (ie no nebulas) background. This means that the star colours are not distorted by Ha data.

Everyone should have an observatory    The design of mine - retracting/slide off roof - seems unusual but it works. If anyone wants a look just get in touch with me and I will be happy to show them.

I have cropped the image to the area of the Bubble - very enlarged so exaggerated star size. I just wanted to prove that the Bubble is actually there.

That's beautiful
