I like this orientation of the Pelican better. Experimenting with the RASA broadband light pollution filter, which looks to be a rebranded IDAS. If ever it should work, this is the target. Still not sure, I'd have to compare with no filter.

EDIT. Tried no filter. On this target with this setup, the LP flter works better.
