Taken over the full Moon cycle in narrowband; added colour a couple of nights ago. Details of acquisition details at the Astrobin link: https://www.astrobin.com/7cqr8b/H/ (https://www.astrobin.com/7cqr8b/H/)
This is a difficult target with such a bright star in the field. I was going to place the nebulae in the bottom half of the frame and leave Navi illuminate them from above but the micro-lensing effects in my hydrogen-alpha master were too difficult to deal with.
Thanks

Lovely star colour in the top one. Normally I prefer colour to Mono, but on this occasion, I really love the mono crop, it shows so much more detail. Presume this is Ha. I have seen much worse microlensing than this, what a pain are some of these CMOS cameras with that problem but I have not heard of anyone with a CCD having microlensing problems before.

Thank you. Micro-lensing shows here as reflections form between the CCD and glass surfaces above it. My CCD has a cover glass but I'm ot sure they are coming from that surface; they may be arising further up, perhaps at the flattener.
Our own Mark has written a script in PixInsight to help identify the origin of the reflections. I am still to use it.

I love them both! The mono version in particular shows lots of detail.
