Description

3 panel mosaic HaOIIIRGB

My second mosaic of M31, this time with addition of Ha and OIII signals acquired by DSLR sensor with dualband Antlia ALP-T filter. I wish I went easier with narrowband nebulae blend but at this point I don't want to go back and process it again from scratch since my pc is quite slow with such huge files. Overall I'm happy about it. Both acquisition and processing of data went much smoother than previously.

Because of long total exposure time it's possible to see many distant and dim objects in the background. I've even found a galaxy cluster over 1 billion light years away from us.
