UPDATE FROM MABULA

I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred  after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.

 

Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.

 

APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46.  Before I release it, I will make sure that everything is working properly and then I will release it.

Overcompensating my lights?

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?
