Stacking with a landscape in the image

[vineyard]

Hello,

Hope everyone is keeping safe & well in the current situation.  At least the stars are not in lockdown.

I had yet another newbie Q pls.  I took some wide-angle shots of the sky from the back garden (ie, with the backs of houses and trees in the foreground and the sky above).  Unmodded DSLR 30x30s on an iOptron Skyguider Pro.  Stacked them on DSS.  And when the image came back, I think the software had registered for the houses because that was sharp, but the stars were all a blur.  Is there a way of getting it to register for the stars not the houses?  (I know sometimes there are region of interest options, although the shape of the sky in the image would be a weird trapezium so I'm not sure how I could specify that!).

Thank you for any tips!

Stay safe all,

Vin

Haven't used it myself in anger, but I've an idea that Sequator might be worth a look for what you're seeking to do.

Have a look at the snapshot page?
