Description

A close up of the star forming region in the Pelican Nebula lots of Herbig-Haro objects are present in the image, notably HH-555 at the tip of the dark dust column, seen near the upper centre. The SII and OIII were shot in Nautical darkness over several nights, with a near or full moon present. The Ha is mostly taken in just the civil darkness around the nautical periods. Luckily this full moon cycle isn't high in the night sky as it nears an eclipse next time around.

My usual star problem is present as I'm still struggling to square the cameras chip to the drawtube. I now think the issue is the drawtube struggling with the weight of camera and filter wheel.

Shot over 3 nights 27th-29th June, hoping the clear spell will last as I'll add to this.
