I have a pile of Ha to go with this but was not careful enough to get framing right over multiple nights so for the purposes of first light, this is 90 mins of LRGB using a TAK FS60, ISO 400, L being False. I really like the FOV the TAK gives for this object. It hangs at the apex of a pile of faint nebulosity in Monocerus which I would love to stretch out but given recent temperatures and a lack of data its not going to happen this year.

NGC2237 Rosette First Light TAK FS60
I have a number of issues and I would love some feedback as this image also is first light for an SBS setup.
My main problem is that I see ghosting on the stars, to the right hand side of each one. I dont know if this is a CLS filter issue or a problem with the camera (Canon 30d) not sitting flat against the focus tube? If anyone is able to advise that would be appreciated. Am using a wide T adapter to connect the camera and it seems flush? It appears on each sub consistently but I am confident that balance and alignment are ok.
On processing, I balanced RGB but avoided increasing hue. A lot of images make the HA really very red but I am wondering that if the balance in RGB is correct, should Saturation/hue be used? Any advice? I suspect there should also be blue in the centre but no NB here so assume the HA from the modified Canon would overwhelm everything else
Usual hints and tips would also be well recieved. There is so much knowledge and expertise on this forum..I have the ICE calender glaring at me pointedly in the shob and sadly January has Mikes sodding Rosette on it...bugger...
Thanks
