Iris Nebula NGC 7023 / C4

Bringing out the all the dusty, dark material leaves me with a horrible background.

The Iris Nebula is a bright reflection nebula in the constellation Cepheus. The designation NGC 7023 refers to the open cluster within the larger reflection nebula designated LBN 487. The nebula, which shines at magnitude +6.8, is illuminated by a magnitude +7.4 star designated SAO 19158.

New QHY168c camera test on Eastern Veil

New camera testing. Different way of working with Gain and Offset needing to be chosen and probably using more shorter exposures than the CCD.
32Mb lights instead of 10Mb for the CCD means much longer processing in APP. Couldn’t use the flats as I moved the camera between flats and lights.

IC1396 Elephant’s Trunk Nebula

Imaged areas around this a lot for HOYs but never this actual part. First time back using the MPCC without the LP filter this time to avoid internal reflections. Stars are better at 3 corners but top right still off – probably focuser alignment.

Because sky conditions were very poor I went back to globulars as nebulosity can easily disappear in LP and fog. APP got rid of the massive gradients and LP quite well I think.
