A quick test shot from Saturday night at Wiruna; Takahashi TOA150, STL11K, AP1200GTO, Astronomik Ha filter.

Due to the clouds after polar aligning, I only managed 5x 10mins exposures, so not nearly enough signal, but I guess it looks promising enough.

With the 6x7 medium format Tak flattener on there, the stars are pinpont to the edges, and no vignetting at all, which is nice.

This is obviously just a very small crop at actual pixel size of the full frame image which is huge and too big to post here. No processing at all bar a dark subtract and median stack in CCDStack.

Regards,
Rob.
