Merope and IC 349 (Sept. 2017)


This is an oft-imaged nebula.  I have imaged it before (search in the window at top left for earlier images).  Merope is the bright star, and IC 349 is the tiny, fan-shaped nebula reflecting Merope's light, just to the right of the star under the diffraction spike.  The nebula may be responding to radiation pressure from Merope, being slowly swept away, but this is not known.  Anyway, the nebula is a challenge to see, and I've taken several images of it.  I think it looks like an angelfish, so to me it is the Angelfish Nebula.

This image was taken at 2353mm with the CFF Classical Cassegrain and the SXVF-H9.
