I use the Lepus 0.62X reducer to get F10 down to F6.2.
Exposure for L=132min., 66*2min.
For RGB it was 20min. each color in 2min. subs.
For Ha and OIII it was 18*5min. each NB filter and Bin was 2*2 for all filters.
Equipment used LX200ACF 16" on wedge and Atik 460ex mono camera. Baader filters.
Thanks for looking.
Kind regards Niels
