I'd like a better #hashtag for the Nottingham Natural History Museum.

In the past I've used #NOTNH, the official abbreviation for the museum cited in research papers and on specimen labels, see picture. But it's not catchy or easy to remember, especially as it seems to be missing the 'M' for 'Museum'.

#NottinghamNaturalHistoryMuseum is an obvious alternative, but that's a lot of characters for a hashtag.

I've considered #NNHM but that's at odds with the official abbreviation.

Any thoughts?
