I have normally taken my Images with a OSC camera. I am trying to use monochrome filtered images I took on itelescope.net.
[7 Lum binx1 300 sec.; 4 Red binx2 300 sec.; 4 Grn bin x2 300 sec., & 4 blue bin x2 300 sec.]
I am trying to combine Lum bin x1 with RGB images with a bin x2.
I cosmetic correct (auto) hot pixels around 1.0 on all images (I have tried with master darks of the correct bin for each image)
I then Star Align with reference to the same Luminance reference on Luminance & RGB images.
I then do ImageIntegration on each set of images.
When I do a LRGBCombination, I see color halos (different colors) around most stars.
If I do just a ChannelChannel on RGB images (bin = x2) I see very few color artifacts around stars.

I am really new at Astro Imaging and would appreciate any or all suggestions on what I am doing wrong
or how to correctly combine.

Thanks,
Brent
