Did it work well at F2?

Yes it did. As it’s not narrowband it will work at any f ratio!

Hello, I wanted to ask you a question. If you had a choice to choose one of two filters in the light zone from 2 to 6 bortles, which filter would you choose- optolong uv-cut , or L-QEF ? Thanks! :)

hey! The UV/IR Cut will be needed in any case even if there is no light pollution. In Bortle 2-4 I would not use anything else. 5 and up if you have old-style (orange colored) sodium and mercury lights you will benefit greatly from the L-QEF. If you have LED (white light) lights the L-QEF will not help so I'd just go for the IR cut in that case.
