Great Image and at 2 minutes .... !
So who needs an astrocam (other than for some mono)?
I remember seeing a Pentax K1 image of Orion and surrounds at ISO 100 in pixel shift mode and being impressed to the point where I couldn't believe what I was seeing in detail/colour and nebulosity. (Integration time/Location/Optics ???). Anyway, it's a really special camera. In FF, it's now also joined by the Sony a7R III (come on Canon & Nikon !)
