Shame about the Mac! IRIS on PC is the best I know for removing Bolton's light pollution. Most other packages can only do simple gradient removal which is fine for Arizona but not powerful enough for Lancashire. Still you should be ok for the constellations.

Phil, our Loans equipment includes Pentax 50mm and Zeiss 135mm lenses, each fitted with a Canon-EOS bayonet adaptor, and as well as my barn-door tracker prototype, we also have the more sophisticated AstroMount.
If you'd like to borrow any of this kit, have a read of our Rules:

and then contact Dean to arrange the loan.

My latest wooden version includes a right-angle mounting, so that all images will have North at the top when using an EQ mount:

Cheers

I'll have a word with Dean on Tuesday

I love your wooden contraptions. :D the binocular one is my favourite so far though
