H-alpha Cygnus / Cepheus update

[pietervdv]

Good day everybody,

Last couple of weeks I have been working with my new 5nm Astrodon h-alpha filter, so I thought I would

share some results. The filter is a very nice upgrade compared to the old 7nm Baader.

The images have been made with my 10" f/3.8 newton and the trusted st8300 sbig ccd camera.

Subexposures ranging from 15 min to 20 min. Almost no processing was done, only curves and

levels in Photoshop and a bit of contrast enhancement. Some more data would be nice as I didn't

use any noise reduction.

The first one is Barnard 344; exposure 5.5 hours:

The second is IC5070 The Pelican Nebula; Exposure "only" 2.5 hrs:

The last one taken last night (still need to add more data, still a bit grainy) ic1396 in Cepheus; exposure 3 hours

Thanks for checking them out and clear skies!

Best regards,
