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.

Hi, 

I am integrating 435 subs (from 60s to 180s) of M51 with darks, flats, darkflats. The result has strange artifacts on the sides and inside the picture (see attached). This never happened to me before.

Integration is set in full automatic, with LNC set at 1st degree - 1 iteration  and MBB at 5% as usual for me. All subs are correctly framed with M51 in the center (dithering apart). Version 1.077 of APP.

Does anybody understand where it comes from and how I can correct it ?   

Thanks.

Philippe

Sorry, missed yours (it's a bit hectic here with my wife as a GP at the moment).

So, that looks a little like some kind of stack artefact, can you describe the exact settings you used? And maybe try 1.078 as well, the most recent version.

Thanks Vincent. No worry. I understand fully the hectic situation you are in ! 

That was with both 1077 and 1078 with all in automatic (no LNC). I solved (?) by using LNC 1-3 (LNC 1-1 was not enough) but I think it is a cosmetic correction to indeed stack artefacts. Never had this before. Could it be the number of subs?

@phfenain

Maybe you are import files from external drive or USB stick ..... Try move your folder on C disk and try again .....

I've just the other day encountered something similar, and could more or less reproduce it.

I had a stack of 757 images (on an external SSD), which required a whopping 500 GB of disk space, which I didn't have available at that the time I started the integration. I got a warning, did the "test for available space" which passed, and let the integration continue, ignoring the ever-repeating warning on disk space.

I ended up with similar artifacts, very likely due to lack of disk space which surprisingly didn't seem to cause further errors for APP.

I am now running a new integration, this time with enough empty disk space. It does take its fair bit of time to complete, so no results yet.

 

@phfenain, did you have enough disk space with your 435 subs?

After about 20 hours of integration I have the final verdict: a beautiful stack when you actually give APP the disk space it needs to perform the stack 😉

With enough space: 

M81 M82 all 2ndLNC it3 St

 

With insufficient space:

M81 M82 all insufficient diskspace
