This week we feature Polaris, the North star, together with the surrounding Integrated Flux Nebula (IFN).
This is really seat of the pants imaging to get this one. Why? Because as we are imaging so close to the Pole we cannot autoguide! We are relying totally on how good our Polar alignment is for how long we can take a sub-exposure. We also cannot dither subs – so this is really basic imaging.
For this particular image I used the Sky90 array and 36 x 5-minute sub-exposures.
