imaged NGC 7129 (Halifax)

The robotic telescope at St Mary's University imaged NGC 7129 for me. Until it stopped. It reported an error, "likely clouds," interrupted my run. It acquired the luminance, red, and green data.

While stretching the FITS, I spotted haze around the cluster in Cepheus; aggressively clipped the highlights to draw it out in this image. SkyTools calls this the Small Cluster Nebula. Quite fascinating. Another of the RASC Finest NGCs.

RASC Finest open cluster and nebula NGC 7129 luminance

Luminance only, 60 seconds subexposures, 10 stacked shots. FITS Liberator, Paint.NET. North is up; left is east.


At the 1 o'clock position, a short distance from the centre of the image, there's a straight line of three equally bright, equidistant stars. SkyTools shows the lower two associated with nebula. Star GSC 04261-1692 with diffuse nebula IC 5133 and GSC 04261-1533 with IC 5132. There is a hint of these in the photograph. I think I see some faint nebula around GSC 04274-1014 which is at the 10 o'clock...

SkyTools also notes LDN objects in the area, 1181 and 1183, both to the upper-right. I don't know if I'm seeing this. Certainly, to the immediate left of the main cluster and nebula, it seems curiously dark...


Shot again to get the blue data.
