LBN239, 241, 243, IC1318a, IC1311 in Cygnus (50MP mosaic)


Recommended Posts

Good day all,

During the first half of June I worked on this 4 panel mosaic of the LBN 239, 241, 243 complex in Cygnus. Besides the bright component ic1318a it was a test for my new asi1600 on some fainter nebulae. I think the small cmos camera is holding up pretty good. Very little noise, I did not use any noise reduction in the post processing. The calibrated frames have been stretched and stitched together in PS.



Scope: 10" f/3.8 Newtonian
CMOS: ASI1600MM-Cool @ -20°C
Filter: Astrodon 5nm h-alpha
Exposure: 20 hrs total (5 min subexposures binned 1x1); Unity Gain setting / 5h for each panel
Resolution: 0.82 arcsec/pixel

A higher res version can be found here.



Thanks for taking a look,

Hi Pieter

A great shot, nothing one sees frequently, very refreshing!

Whats you're plan going ahead or you're putting this one to bed as mono?

Kind regards, Graem

Thanks, never hurts to go off the beaten track now and then.  This one will remain a mono picture.
