That scope shows tremendous promise.

Yes that is definitely coma in the corners. Bummer. Its either a spacing issue or the corrected circle is not as wide as they thought.

Yeah, but if I double that exposure to 2h 20min with my f/5 FSQ, I'll blow that one away with better star images out to the corners, and by applying my 11 herbs and spices to the processing, the image would be spectacular. I don't think the RH200 has more than a 60mm image circle. It may be more like 50mm. Compare that to the 80mm image circle that more than covers the 16803 array. So we shall see. I do want to try before buy. Hopefully Geno, Geno, and Geno will be at AIC this year.
