Amazing image! Great video :) Could I ask what's your Bortle Zone?

[@OuttenAstrophotography]

I live on the cusp of a B 3.5 to 4

Very nice result and Thanks for all the videos. I've been assembling my own Rok 135mm kit and am curious if you've had any issues using the L-Quad filter at such a fast focal ratio (do you use f/2 or stop it down?). Also, have you used it with any other filters like the L-Extreme? Thanks!!

[@OuttenAstrophotography]

With the l-quad I have no issues with band shift at f/2 but when I use my optolong L-Ultimate I have to step the system down to f/4 sadly

@@OuttenAstrophotography Thanks so much for the reply Hunter! I suspected that would be the case for the L-X/U filters; not ideal, but still workable.

[@franks2725]

I apologize for asking this, but can you tell me how you are connecting your camera/FW to the lens? I'm struggling with back-focus adapters. I think there's 17.5mm to fill after accounting for the camera's back-focus (17.5mm) and the FW thickness (20mm), but I can't tell what you are using and I'm getting confusing input from others. If you have a video on how you did this, you can simply provide that reference (I couldn't find it). Thank you!

Here email me I'll see what I can do there is different back focus depending on if you are using a filter drawer, EFW, etc. [e-mail]
