Thanks very much Barry, looking forward to seeing your results - you will be using a Newtonian?

At magnitude 9.7 you've done well to pull that one out of noise.
You've shown great detail.
I notice you use an RCC1 corrector on a 10" f/4 Newt with a small H694 sensor.
Do you know how a larger QHY9m with a KAF8300 would go on the same system?
I am thinking that there would be vignetting & not 100% illumination?
( I am just wondering if my similar optical train would work on such a Newt. )
cheers

Thanks Allan.
depends on seeing, but the 250 Newt would be a pretty good match to an 8300 in average conditions. If you got some really good seeing, drizzle stacking would be the go, since the larger pixels of the 8300 would limit sampling in the very best conditions. Pity you are not closer, we could try it out.
Vignetting would be an issue at the extremities of the chip, but for galaxies, that is a minor concern.
regards Ray
