NGC 6914

NGC 6914 in RGB

This dataset won an Astrobin top pick nomination here, processed by Taras_M.

NGC 6914 is a reflection nebula located approximately 6,000 light-years away in the constellation of Cygnus. Ultraviolet radiation from stars in the Cygnus OB2 association ionize the nebula’s hydrogen.

RGB only, as the goal was to go after the blue emission nebula, in a redish background of H Alpha clouds. I was also very pleased to find a complex system of dark nebulas, adding some pattern to the final image.

Please note: new flats. A speckle of paint in the corrector (a Televue Paracorr) detached and is visible in the flats. Images, once flat corrected, are good. The speckle is not moving inside the paracor either (I think). Current calibrations files are available in xisf (2023-09-25) and fit format (2023-10-01).

Needles to say, I am not too happy with the Paracorr flaking out on me (no pun intended). It is also fairly ironic that the first part to fail in this home made / ATM scope is a commercial part. See details here.

Also when trouble-shooting the corrector, the camera train & corrector was disassembled and reassembled, and there is an image rotation of 4 degrees when comparing images before intervention and after. This slightly reduces the field of the image for targets straddling the intervention date, like NGC 6914. Of course if I had a rotator that would not be an issue. However Moana does not have a rotator – at least not yet.

Last probably not doing a starfield on this one just due to opportunity cost.
