Description

Another go at the Cave Nebula from London.  Using Ha data from 2016 and mixing it with L data from the larger refractor and OSC data from the smaller one taken at the end of October, beginning of November 2021.

First added Ha to the R data from the OSC shot, then L and Ha to the extracted luminance (improving the resolution and detail to some extent in the central region) and then Ha to that new luminance.

Extensive use of Russell Croman's new StarXTerminator which works very well.

For beautiful version of this object see Stefan Roth's version or Emmanuel's.
