NGC6888 widefield


Recommended Posts

A widefield shot of the Crescent. This is a 6 panel mosaic consisting of 5hrs in Ha and O3 in each panel giving a total integration of 60hrs. The mosaic was constructed in APP and then processed in PI minimally with a little noise reduction and then colour combined with the standard mix. I added the Ha layer back in PS to bring back some of the detail. I have attached the Ha as I like it too!! Hope you like them, C & Cs welcomed as always!

Thanks Dave, the camera has been recently serviced so I’m not sure it’s that. It’s only on the bigger stars too. 

It's a normal cosequence of the sensor construction, not a fault.
