Very, very nice but I noticed a blue streak to the right of Beta Centaurus in all the images you posted. Otherwise fantastic image, well done.

Great colours and detail Steve.

Nice composition also.

artifact get on the LHS of most of my QHY stuff.:shrug:

Nice images Steve. I prefer the one with the southern cross in it.

Hi Steve,
Is this normal for QHY cameras?
I want to buy one but such a line would have me asking for warranty.

[kinetic]

I should say, it is not necessarily a defect....I haven't investigated it
to any extent.
All I know is that after a typical debayer and very extreme stretching of
a stack with anywhere from 50-100 images, there is this line.

It could be many things....

I don't use darks most times...you can see this in the form of blue dark holes/streaks dotted thru my recent images.
Darks will remove most of this type of 'in camera noise' if that is what it is.

I never use flats, although it doesn't seem like a thing a flat would remove.
My post-capture processing is usually a rough hack. I tend to over-stretch, which would emphasise this type of artifact.

FWIW.

Thanks for the reply.
It would be good to know what that line is.
I am just looking around for a new camera & seeing
what results people get.
cheers

The line is not a standard feature of QHY camera's. Not sure what it is though, program used to debayer/stack? If it was directly in line with a star then I would say your clamping setting is incorect but it is not that. Great field Steve, certainly works well with the camera lens.

I get the same line when I use both Neb and DSS, Mark
