Astronomik 50x50mm filters.
Hi
I was hoping to use these filters on my DR350, but unfortunately, there is too much transmission lost on the NB filters because the system is f3 and I discovered this by contacting Astronomik before installing them. So, the NB filters remain unopened, and the LRGB were used for just a couple of nights before I changed them out for another brand. The RGB are the Deep-Sky variant, and the lum is the L1 variant. The NB filters are all 6nm
Bought today, including import costs, this set would cost you $4000AUD. My sale price is $2750 - that is a $1250 saving, especially as the 3 NB filters have not even been opened. Shipping is on me.
Regards
Martin
