Re: How do I take Flats with a HyperStar?

I use a Hyperstar 4 on a C11 and there is significant vignetting with an ASI2600MC-Pro CMOS camera which requires flats. For flats I have a dew shield which I can point vertically upwards and drop a light panel over the top. The light panel is extremely uniform and can be bought at a very reasonable price from Amazon - they are used for drawing (tracing).
