Hi All
I have an narrow band filter for HA / Oiii and the subs look fine but when processed as RGB all the colours change and its looks wrong. Nice but wrong
With narrowband do I select RGB like i would for any LP filter?
Filter is the Antlia ALP-T
Many Thanks
Paul
May have found the answer...just doing it now
"@stephanhamel22 Hi! This is quite simple. Load your lights and calibration frames in tab 1. Then in tab 0 select the Ha - OIII extract Ha algorithm. Then go to tab 6 and click integrate. When done, return to tab 0 and select Ha - OIII extract OIII. Click yes when asked if you want to normalize again and in tab 6 click integrate once more. That’s all. "
Hi All
Sorry for the questions.
Once I've extracted the Ha and Oii how do I combine them in APP...?
Many Thanks
Paul
Trying this method in this link 🙂
Losing faith now
I sont see tab 9..never have...asumed it would be there when the process requires it
I give up!!
Tab 9 its called tools in the program...all other tabs have numbers so call it tools or add the number 9 to the tab
Tried to follow the advice but what is said does not reflect the tool...i keep getting a B&W file when combining as its not clear how to load the two files
Help is non existant outside the forums
Painful progress 🙂
Got a clour image from 6 subs
now to try all 100
Ha and OIII only will not produce a RGB image, the algorithm in the RGBCombine tool will then simply assing some OIII to G and B. That will give a kind of two-tone image which is normal, you only have 2 data channels. With narrowband you can assign them to RGB in any way you like with the formula in that tool. If you want to make a RGB "true-color" image with added narrowband data like in the tutorial you linked, you need RGB data as well.
