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.

Hey all.  A few days ago I was digging around here to try to get a process to stack a comet without star trailing.  I found a solution that I found pretty easy!  I made a little video if anyone finds it helpful.

Problem is all those rejection techniques end up damaging the details in the comet tail.  I tried a lot of them with different lower and higher values.

To the developers:  we need at the minimum a batch mode to calibrate and remove the stars on all subs individually. AND then the ability to register them on the comet nucleus and stack them without the stars. 

Removing stars on the stacked image creates a lot of damage.  This effect is a less damaging when stars are removed before stacking.

Is this something we can wish for,  hope for before the next bright comet?

Yes, we moved this feature way up our list, so we are going to work on that sooner. Of course it always becomes the top most feature for everyone when a comet arrives, I get that, but we're working on multiple requests as always. 🙂

@thedevelopers, this was first promised back in 2020, one of the reasons I purchased my licence, other softwares have this feature (Pixinsight) already

This is great, but I'm really struggling with the Photoshop phase. Is there any chance of taking me through that more slowly or do I just need to learn photoshop better? Somehow, the subtraction doesn't work for me and this is probably a noob-thing, but I can't figure it out myself.

Sure!  I would be happy to.  What is happening in this step is that you are subtracting the same elements out.  So, make sure the blurred comet with stars is one layer, and the blurred comet without layers is the other, one on top of the other.

 

Then -> Image and scroll down to Apply Image.

From there you will see a dialog box.  Where it says BLENDING, change it from MULTIPLY which is the default to SUBTRACT.  At this point, the box with your photos underneath should turn black.  

Then, in the box marked LAYER, change it from BACKGROUND to either Layer 1 or background and you should see the blend happen.  

 

If this does not work, let me know at which point you are stuck and i will try to help.  Maybe take some screen shots?  Cheers!
