Update on the 2.0.0 release & the full manual
We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version.
Once 2.0.0 is released, the price for APP will increase. Owner's license holders will not need to pay an upgrade fee to use 2.0.0, neither do Renter's license holders.
Hello!
Â
So, this is first light of my new telescope + camera, and I am loving the result so far!
However, I noticed that I still have visible satellite trails in my stacked image. Faint, but definitely visible. At first I thought they were reflections when I just saw 2 faint ones in the final image, but after stretching they became more apparent.
I had 50 light frames (each 3 minutes exposure), and kept everything on the default settings in APP.
StarXTerminator shows it the best:

Any idea on how I can prevent them from being in the final stack?

Edit: I also used the Sigma rejection in the "Integrate" tab. Using the "average" integration. This made it slightly better, but it is still visible.

Are you dithering? That might help (bigger steps) as well as taking more data, if it's particularly busy that can be an issue. You could also change the integration parameters indeed, maybe setting the agression a bit higher to like kappa high of 2 or so.
Hello,
Yes, I have been dithering. I will try a higher Kappa next time. I was just a bit confused, as I never had any issues with satellite trails in the past, especially not with 50 subs, so I was/am kinda confused.

Just to clarify, a more aggressive Kappa would be lower. 🙂
Thank you Vincent, changing the Kappa to 2 did the trick!
