About this image

This set of subs was built up over 3 shoots 28th and 30th March and 30th April.   total of 145 subs from which I have selected best using DSS and ASTAP

Best result so far from these 92 getting the faint spirals to begin to emerge.   this is quite a tight crop from the 600mm refractor pending my new scope on order and taking an age to arrive
