Deep sky stacker / comet stacking

[frewi808]

deep sky stacker question, how come the bullseye do not find my comet ? Is there a manual way to make it center my comet ?

I think it’s press shift and click mouse on the comet

First you need to set a reference frame.  Find the image with the highest score, right click on it and then select as reference.  Your should get some symbols on the RHS; select the comet one.  As long as your images form a time series i.e the same time interval between them all you can click the centre of the comet in the first and last frames and DSS will stack with whichever stacking regime you want.

In settings under Comet you can stack on the stars (comet trails), stack on the comet (stars trail) or try to stack on both which takes quite a bit longer.  I found stacking on the comet gave the best results.
