Description

NGC 1491, an emission nebula in Perseus. Not a very common imaging target, one of the challenges of this nebula is the large dynamic range required to capture both the very bright core and the very dim outer regions. 

This image was captured with the CDK14 with a custom configured imaging train that enables an off axis guider to be used in conjunction with the dedicated Planewave 0.66x focal reducer.
I wrote an article on the custom setup here:

A significant total integration time of 42 hours with the low noise QHY600m (gain56) and 3nm Chroma filters allowed a good amount of faint details to be extracted. The complex clouds seen in the background were better illustrated below, a starless version, to emphasize the nebulosity:
