Hi

I have just put together my first mosaic using APP and it was reasonably successful. This was of 6 panels of the sky covering the Veil Nebula system. I used the same system / settings for each of the panels. 

For the mosaic I just used the common calibration files, darks, flats, etc. added all the lights and set the processing going.

However I would like to include data of that area of the sky taken at earlier times using different cameras/scopes.

Firstly is this possible?

Secondly, if so, how is the calibration done. Do all the lights have to be pre-calibrated independently before the subsequent processes?

Thanks in anticipation

Frank

@thedwo Hi Frank,

Yes, this is possible.

There are several approaches to this.

One possibility is to process all data of the different telescopes separately. Once done you can load all integration results as lights into one session (no calibration data since that already was applied) and go to tab 6 and click the "integrate" button.

Another possibility is to process the data of the different telescopes together in one go. You can then load the lights and calibration files per telescope in separate sessions and then go to tab 6 and click the "integrate" button. Depending on the APP version you are using and whether you combine mono and color data, this may or may not work. Also, all individual lights will be aligned with each other which can potentially take a long time and require many system resources depending on the number of lights. It may be easier and safer to go for the first option.

HTH, Wouter
