Please let me start by saying I'm a complete newbie/noob when it comes to mosaic(s)! Now having got that out of the way I hope I'll be able to explain what I'm thinking about with regards to my topic...
Say I'd like to create a 2*2 mosaic of the Iris nebula. I create a sequence using N.I.N.A and fire away. I dedicate each panel an equal amount of exposures, say 20 * 180s, resulting in four hours in total for the mosaic BUT how do I handle flats? Say I need to make some adjustments between the panels which will, ultimately, alter the image train - maybe not much but as we all know "not much" is a very relative term when it comes to light!
The way I've been thinking about this is as follows:
Code: Select all
foreach night of exposures
foreach panel
take lights (only shooting OSC)
take calibration frames for each panel
Code: Select all
foreach panel
foreach night
stack light frames together with nightly calibration frames for the panel
stack the result creating a "super panel" with all stacked nightly data + calibration frames
finally stitch all panels into a mosaic (is Microsoft ICE useful here? Other tools?)
load the mosaic into StarTools
