LPS-P2 50mm Unmounted Filter

Used these last night with my monochrome camera and the 3.0mm thickness fits my filter wheel perfectly without any tilt. The par-focal design meant I didn't have to refocus between filters, which saved a ton of time on narrowband targets.

Finally got my filter wheel set up and these 3.0mm thick LPS-P2s fit perfectly alongside my AstroDon set. The par-focal design means no refocusing when switching between filters—a huge time saver on a cold night.

Swapped these into my monochrome imaging train and the parfocal design really saved me time refocusing between filter changes. The 3.0mm thickness gives a nice rigid feel without adding too much backfocus.
