Looked like around 4k price wise.....way outside my range....but like Jaydean said it's also about the scope that you hook onto...alot of astrophotography are stacked and processed heavily...but the camera body/Frame being full frame (35mm)will be a great improvement in the Snr-signal noise ratio (image noise)
I have been watching this closely and at first thought didn't think I would bite, but after more reading I have the feeling it will be able to be used in normal shooting conditions aswell as astrophotography. And the 15min long exposure is quite nice. I wonder if this is my next upgrade
