astro mick Posted October 8, 2019 Share Posted October 8, 2019 Hi. After a spell of poor weather I managed to get out a couple of nights ago. I chose IC5146 as it was high in the sky.I imaged this with Ha and RGB Filters.About 2hrs per Filter. 80ED and 73ED scopes were used. Fully calibrated with calibration frames. I could,nt push too hard as the Blue was giving me the dreaded blue halos. If anyone knows a good tutorial to handle these halos,please let me know.

alan potts Posted October 8, 2019 Share Posted October 8, 2019 Very nice image there, I actually rather like the blue halos. I guess using a mask is the answer, I know how but rarely do, as long as I get a reasonable result whilst learning that pleases me. I'm happy.

astro mick Posted October 8, 2019 Author Share Posted October 8, 2019 Thanks Alan,always appreciate the comment. I don't seem to be getting much better at this lark,so may stop posting.I,m still happy at my own results,and that's what counts. However I,ve said this before,and I,m still here.(LOL).

RobB Posted October 8, 2019 Share Posted October 8, 2019 (edited) I was watching this AstroBackyard tutorial last night (trying to soak up as much info before I begin my baby steps in astrophotography). Trevor, at one point, goes into removing halos. https://youtu.be/5GgruZ-1zQ0. I think just after halfway. Edited October 8, 2019 by RobB Link to comment Share on other sites More sharing options...

Mick I dont know why youd stop! I always enjoy looking at your images. This is another nice one, with plenty of detail. Maybe a tad dark on my screen tho?

I'm not sure I know of a tutorial but one way I have found to reduce the problem is to take the Blue image into PS as a tif (from PI) and run the 'Reduce star size whole image' action from Annie's Astro Actions. Sometimes I run it twice for good measure. When I take the tif back into PI I can combine the RGB without getting the blue halos. It's probably cheating but it works. You can also use Photoshop : Filter - Noise - Reduce Noise and set Reduce Colour Noise to 100% but I have concerns that this does more than just reduce the halos.

Hi Mick If you don't have Annie's Astro Actions I would certainly recommend them; lots of useful and helpful stuff for sorting image problems/issues and a bargain at only $15. Good lcuk.
