My method for my two Mega Mosaics, Orion and the Galactic Centre were to make a base layer in PI with their Star Alignment, process. The GMM process which can make a mosaic from the Star Alignment base layer did not work for me. It left halos on stars, dark holes, distortions etc.

So I let the SA process register and build the base layer. Then I…[Read more]

Mabula,

Yes I like to get straight in there and test the big mosaics 🙂

I don’t quite understand the Thin Plate Spline bit. That sounds like a method to calculate the registration for the panels.

So let me mention where the frames came from

1) FITs were calibrated in AstroArt 5 with Darks and Flats applied here to stack the master 4 hr…[Read more]

Would it be possible to auto-populate the LP boxes with settings I can change?

No option to make new lights and calibration frames using only APP?

Thanks Mabula, I will do that tomorrow (31/3).

I move masters to a different directory as the work directory, it would be nice if I can tell APP to change the location of the master which is in the list.

Maurice, Mabula – When I was using a DSLR, I also liked to capture my lights at ISO 1600 and Flats at ISO 200 (longer exposure means that each flat has better SNR).  What I would do is to use Bias frames at ISO 1600, and flat darks at ISO 200 (and, of course, same exposure time as my flats). I had used Images Plus for calibration, and it would d…[Read more]

Wow! You’re putting APP to the test ;-)

If the original Panels are affected by thin plate spline transformations, it would be hard to fix, since then the distortions aren’t scientifically exact anymore. The will deviate unlogically from the rectilinear projection due to the thin plates.

But, there are several options that you can try to get a…[Read more]

Here is the 25 pane version, used with the DBE files. Very good blending result for brightness, gradients and detail.

Two areas of overlapping show star distortion.  Whether these can be joined without issues by other settings I m noy sure yet. More testing to do.

This took 3 hrs on the laptop to put t…[Read more]
