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 Mabula,

end of last December and the last 2 nights in January I captured the Pleiades in both luminance and RGB with my SBIG CCD and SW 80 mm APO. As usual I process the images in APP using the "Multi Channel Processing". In the integration tab at "Multichannel" I select "Integrate per channel & All". I really like this option because the integration of all the channels combined (L +R, G and B) gives a slightly better "luminance" stack then when I only stack the luminance frames.

I ran into a problem with this. When using the "Multichannel" option the stacks from R, G and B have some strange borders at the top and bottom. Strange thing is that when I process the frames individually (i.e. without the "Multichannel" function) and with the same settings, the borders are just fine. Even stranger is that the luminance stack doesn't have these borders. The combined stack (R, G, B and L) also shows these borders.

Attached you'll find 2 stacks from the B-channel: one stacked with the "Multichannel" function and the other without. Do you have any idea what causes this problem?

combined stacking
separate stacking
