It's hard to get sick of seeing Eta images Paul. That one is a beauty. Is Houghy missing that 350D yet?

For only 30 minutes of exposure, it looks nice to me, Paul. Nice wide FOV.

Indeed, the FOV with this instrument makes Eta a prime target. Nice composition. Keep an eye on the red channel as it appears to be black clipped. This has resulted in heavy weighting of the red limiting the green and blue channels. Look forward to seeing more.

A fine looking image Paul, this is one area of the sky I never tire of viewing.

Love how it stands out from the sky background yet none is over exposed or burnt out.
