In this image I wanted to bring out details in the disk so I pushed the development of the star clouds. I also wanted to see how well I could capture images with no filters and get decent signal to noise from a country site.

82 subs at 60 s with no filter = 4920 s 10/24/2019 moon = 17 % illuminated
35 subs at 100 s with a Lumicon deep sky filter =3500 s 10/25/2019 moon = 7 % illuminated

Total integration time = 2.3 hr
