Hey all,

Just to add to the confusion, what about the Optolong L-Pro filter? I'm heading down this path as well - same scope and camera as Bodon - and pondering which filter to get.

The attached images are the camera's frequency response curves and the L-Pro's block / pass diagram.

To my eyes, the L-Pro would be a better option because it allows more colours to reach the camera.

So far, my shopping list consists of:
1 x ZWO 2” filter drawer
1 x ZWO 2” to 1.25” filter adapter ring
1 x Optolong L-Pro 1.25” filter

It's also tempting to get a second filter holder and adaptor to mount a UV/IR cut filter for if/when the skies are darker than usual or I'm at a dark-sky site.

For what it's worth, my backyard is Bortle 5 to 6.

Cheers,
V
