Re: Televue Ranger for deepsky object photography
Hello there Bob,
I've tried my ToUcam Pro with M42 and M57 with much larger ;-) aperture
NP127 and it just won't work even with gain and gamma cranked up really
high. This camera will need to be modified for long exposure.
However, brighter open clusters would come out ok, nothing spectacular.
Don't know about the Canon Rebel.
