I run the V-curve first light on my Esprit100 with a ASI071C camera without a problem.
Recently I rigged-up my 10" f4 Lacerta newton with a ATIK16200 camera.
When I now want to do a 1st light V-curve I need to set my 7nm Ha filter and even then the exposures are 0.4 sec. The minimum exposure of this CCD camera is 0.2 sec.
I use the default settings.
When I set the Lum filter, the star image is over exposed (flat top) and Robofire can’t make any sense out of it and keeps endlessly on running in one direction until I get a message about the algorithm being unable . . .
How do you guys handle this?
