Description

This image is slightly over-stretched to reveal the faint PN nebula (quite Soap Bubble like) and the faint whispy tendrils of Ha.

I imaged this in wider field nearly two years ago and wanted to focus on the PN region (see here, https://barrywilson.smugmug.com/Image-Galleries/Mono-Images/i-3hQdvm7, and here, http://astrob.in/211149/0/). I hoped to collect OIII data for a bi-colour, and possibly RGB too. However, I am due to go on holiday soon and will strip out the gear in the observatory until I'm back in early August. I hope to collect more data then.

This target is not often imaged - maybe I can encourage some of you with longer FL scopes to train on the PN and its Soap Bubble-like presentation :-).

Thanks for looking.
