The Rosette Nebula - WiP (aren't they Always!)


Recommended Posts

Rosette Nebula

 

 

Acquisition details

William Optics GT81

ZWO 1600MM TEC

SkyWatcher EQ6R Pro

Altair Narrowband Filters

 

Finally managed to get a couple of clear nights in Feb so added loads more data and played around with some new processing workflows in PixInsight. I decided to leave a level of green in the image as I think it helps, totally removing the green looks a tad bland to me.

 

Still need to work on pulling out some of the fainter details and cleaning up the stars

Very Very nice! Similar framing to the one I've been working on, and you can really tell you have more integration time. Some of the fainter nebulosity really pops.

 

If I'm pixel peeping I think there is a possibility that you may have some tilt or backfocus issues as you have slightly elongated stars in the top right corner.

Thanks.

 

Well spotted 🙂 I think it may be an issue with some of the subs. Its only visible in this image so I am guessing I may not have tightened things up when rotating the camera. I'll check the subs and see what I can find.

Really nice ! How long have you spent on each filter ?

 

Thanks 🙂

Its about 6 on Ha and about 5 on Oii and Sii. I seems to spend more time processing than acquiring data ! I'll hopefully finish this off over the next week or so as work permits.
