[APML] New image: The Crescent Nebula

[Juan Conejero <skycad@ctv.es>]

Hi all,

Our last production is an integration of four 1-hour shots. It's NGC 6888 
on E200 through our LX200 12" + IDAS LPS. As usual, you can see it at two 
resolutions:

800x800:

1024x1024:

This image is the "first-light" of our new image processing software 
project, in which we have been working hard during some months (and many, 
many more that are to come). So far we call this monster PixInsight, but 
this name may well be changed. The news with this image are mainly related 
to noise reduction, which has been done entirely through wavelets processing.

We continue very happy with our IDAS LPS. Besides wonderful light pollution 
suppression, an additional effect of this filter is due to its cutoff at 
about 420 nm. It acts like a minus violet filter, which is fine since it 
renders Halpha truly red, unpolluted by UV.

Comments welcome,
