Hi Mabula,

I've now managed to process two images with APP using the trial license and am very pleased with the results, see attached Ghosts of Gamma Cas and Iris Nebula. 

I have used several other imaging packages in the past so have some idea what to expect but generally I've found the package very straight-forward to use once I'd got to grips with preparing calibration frames and experimented a bit with the slider controls on  the RHS of screen.  Overall I am very impressed with its capabilities and look forward to seeing what future releases will bring.

On a minor usability issue I find the placement of the RHS sliders and the associated labels slightly misleading, ie I find myself incorrectly moving the slider below a label (as it is the closer) when I should be moving the one above.  If you are able to move the relative spacing of the labels and slider I think that would significantly improve useability, at least for me!

Looking critically at my images they clearly benefit from additional data capture to bring out the fainter details better - but imaging time in the UK is horribly limited. Apart from this I believe I have a small issue of banding in the darker areas which I think is due to some incorrect bias correction.  I am using a stack of 140 bias frames.  Would you agree with my assessment and do you have any

C4 2017 10 combine RGB v02
IC63 RGB combine v04j

suggestions as to how I might reduce or eliminate this effect.

In summary, thanks for producing such an excellent package and I think you will shortly have a purchase in the near future.

Regards

Mike

Hi Mike,

Thank you for your nice compliments 😉

I have heard this complaint form other APP users as well, so I'll try to adjust the sliders appearance so it becomes more clear.

At a first glance, the images look fine, I don't see a clear fixe bias (or dark signal) pattern that indicates bad calibration. Maybe if you can show one of these images with a much stronger stretch so it becomes more apparent?

Kind regards,

Mabula
