Is this just a bug or a deliberate omission?
Good question !!
When observing certain special celestial bodies in SkyAtlas, the filter will be automatically turned on. We will optimize this in the future to make Seestar smarter.
AstroImg@ZWO Except it doesn't actually. Items in the Skyatlas with the little green dot on them used to mean the LP Filter would engage automatically. It no longer does. Can you give me an object for the northern hemisphere in the Skyatlas Catalogue that I can try for myself?
