About this image

I collected two sets of data consecutively in this region, with about 80% overlap – the original framing caught only half of the planetary nebula so after a few night imaging I moved the field a little. In fact none of the raw data sub-frames looked very promising and I left them for almost a year before processing.

But I'm glad I did get around to it. I processed both sets together and as part of the process produced a starless image using the StarXTerminator plugin for PixInsight.

Here we see a region of ionised hydrogen (HII) and. The various patches of nebulosity have been individually identified in Beverly Lynds' catalogue of Bright Nebulae (LBN), as can be seen in the mouse-over. There's also a small planetary nebula, PK085+04.1in the lower left part of the image.

The image frame is located a little to the north west of Deneb.
