Just started to use the mosaic function in SG and have some images taken.
I would be happy if I could get suggestions on software to use for stitching them together?
I have software for making each frame ready. I would very much like to have an automated process as I have many frames for every position.
also - there’s almost no way for PI to fail if you use the ImageSolver/MosaicByCoordinates/GradientsMergeMosaic flow. in this method a mosaic can be made even if the overlap between panes is zero (or even less than zero).
GMM does help with that, but you have to have good SNR in each panel and remove any LP gradients beforehand. it probably helps to use dnaLinearFit to get the panel brightnesses similar before attempting the stitch.
is a 3x2 mosaic made using this technique. it helps that the image is Ha in terms of lessening the gradients but i still had to remove them.
Beautiful image. Might I ask. . .When using MSICE, did you do any preprocessing of the individual mosaic panels before using MSICE, like stacking with calibration frames and/or stretching? I found I needed to do some preprocessing before using MSICE but getting each mosaic panel to have good balance between each was difficult.
I used Maxim DL. Calibrated all frames with master dark. Combined with Sigma Clip, then Digital Development (Filter type none) on the combined pane. Saved as TIF 16-bit uncompressed with Auto Stretch.
Then Simple Panorama in MSICE.
Levels on the stitched image in PS to brighten up it a bit.
That is a great first attempt - looking at the image, however, I can see lines and joins. Similarly to others, I use PixInsight, with DNA linear fit and GMM. I do not try and register them to each other, but to a background star canvas, generated by StarGenerator script.
You do need considerable patience and my PixInsight project exceeded 32 GB at one point!
