Not that I've spent more than one night imaging this year due to weather and other issues. I've been pondering getting a large achro for imaging. of course we all know they are no good for OSC imaging as all colours don't come to focus - or if you are capturing Luminance with a mono cam. I am fairly certain there is no issue with NB imaging. so in short I suspect if most of the imaging is done in NB it should be fine for that purpose.
I'm not so sure on RGB imaging (mostly because I haven't done it properly yet - just dslr and NB). of course with RGB obtaining L is very important but how well does a synthetic L work from RGB data is it comparable? does it yield a result 90%75%50% as good?
Is an R or G or B filter narrow enough for the achro colour/focus issues?
Most of the time will be NB but curious as to know the situation with RGB. Of course the plan would be to go large ~152mm f6.5(or do we go in inches now its bigger aperture territory?
)
