LDN1165 - Dark stuff in Cepheus

[powerlord]

I've been intrigued by this thing as it's shown in DSS data when you look at it - say in Stellarium (bottom in blue):

 

is it real or an artifact ? why is it a bubble in the middle of nothing ?

And @ollypenrice's recent post about sort of random or seldom imaged bit got me thinking about it again - so I thought I'd give it a go.

I don't know why it's a bubble in nothing in DSS data, but what it is, is LDN1165. Apparently, Hubble imaged it:

Interestingly is you zoom into mine, you can see the same orange star forming region.

I shot this thursday night - 8 hours of 10 min subs with my 200pds and asi2600.

Nice capture. I think the oval shape is an artefact due to how Stellarium displays a few selected DSOs.
