Title: register new images with existing ones
Post by: alcol on 2018 June 19 11:18:22

Hi folks, looking for advice.

If I have a batch of images that I calibrate, register and integrate. Can I save one of the registered images from this batch so that if I take more images at a later date I can simply register them against the saved registered image from the earlier batch?

Thanks for clarification.

I always 'mark' the image I use for registration with an _* i.e M42_L_600_* so if I add more images at a later date I can register them to the same one.

Hi,

For DSLR images I process each nights images up to and including the debayer process.  Then use the script "SubFrameSelector" to find the best SNR and Eccentricity image for all the images.  I guess you can use your predefine best image as the reference.  I then continue to StarAlignment and add all the debayered images for various night and continue the pre-processing with LocalNormalization, ImageIntegration and sometime DrizzleIntegration. 

I assume the process is very similar for CCD images, except there is no Debayer required.

Look up

For each image I have a Word file, in which I enter all data and parameters. The reference image for image integration is also listed.

The reference image for ImageRegistration was meant.
