Description

This is a three frame mosaic.

Ver.A is the original 3-frame mosaic made with TAK Epsilon 180ED.

Ver.B is a wide-field image taken with Sigma APO 180mm/F2.8. It serves as the registration reference for the mosaic, as well as background reference for removing the background sky gradient in each mosaic panel.

Ver.C (Final) incorporates this older image of mine:

This helps to enhance the S/N and resolution in the R-CrA/NGC6723 region.

Just for fun, this is the link to the film images for this region I made some twenty years ago:
