Description

NGC4490 and its interacting neighbour NGC4485 (together known as ARP269) made for an interesting and timely target for me after a few months being unable to image at home. 

My version is made from 115 x 300" Lum and 60 each of RGB 180" taken over the evenings of 13th and 14th February. This was first light for the new QHY294M which has replaced the QSI683 but more or less has exactly the same field of view, and there was a slight misalignment between the two scopes of the twin rig hence the fov in the wider shot does not reflect the chip due to some cropping.
