Thanks Rick. Its an extraordinary region. Also there are some surprises in that area that the Proline picked up. An image from that coming shortly.

Having Rho and those golden star clouds together is a delicious contrast.
The golden star fields are an amazing feature. I was happy there was enough field of view to capture both.

Hmm I have 3 cooled mono cameras. Those Pentax 67 lenses are quite cheap, under a $100 as I recall. This image though was with a Sony A7r2 mirrorless full frame camera with a backside illuminated sensor with the latest Sony sensor wizardy. If it were a mono sensor and cooled it would kick some serious goals. At ISO1600 read noise is less than 1 electron.
