I regularly study my copy of The Handbook of Astronomical Image Processing by Richard Berry and James Burnell.

Do you ever have trouble with your imaging train and you just can't figure out what it is?

Sometimes, regardless of focal length, you just can't fit it all into one frame.Mosaics to the rescue!A mosaic is a composite of multiple frames connected at their edges to create one large image.

While I do a lot of imaging from my backyard, I try to get to my local dark sky site for a few days once a month during the new moon.

I'd like to tell you about a technique I've been using as part of my processing flow here lately that has stepped up what I can get done.

As I went through all the old observations I noticed we had a good set of R, G, and B for NGC 1300, but no L. We have other sets like that in there too.
