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.
Hi Guys,
I shared my rough image on a different forum and they thought my my image was overcompensated in the corners.
Now i hadn't given it much thought up until now. I just cropped out the edges.
What is your view on this?
I have three images here: https://photos.app.goo.gl/5UksYPPz3KHGt8sB9
One sub, one callibrated sub and then the stacked image with 45 subs.
Any thoughts?
Maybe i can adjust settings or so.
The sub looks as expected. There is a dust devil and vignetting.
The calibrated sub looks as expected with a possible exception of the upper rim. but the dust devil has disappeared and the vignetting as well. At least at a quick inspection.
The stacked image looks as expected as well. Apparently there is a significant drift between at least several of your subs which explains the stacking edges. If you crop those off then you'll have a great image.
What did the other forum mean exactly when they wrote "overcompensated corners"?

Thx for the reply, Wouter.
They said it looked overcorrected.
well if the edges are overcorrected, so will be the rest of the image, even though the effect is not that apparent there
The big difference in subs is because of dithering, meridian flip and stuff like that. I usually crop it out, but the guys on the NINA forum probably use pixinsight to stack or so. I don't know exactly. Would it make a difference to crop everything to the reference frame, instead of just showing all?
