opinions on dark field microscopes

dark field microscopes (DFM)


morning all,


I want to look at and photograph some frozen H2O crystals.

If anyone has done this or has experience with DFM's with photographic capability - I would value your opinion please.

My general questions at present are --

'what mag. would I need to look at individual crystals?'

'If a particular scope has photographic capabilities - can common digital cameras connect to it - eg. Canon slr's or other?).

If you are experienced in photographing the crystals - what problems are encounted?

I assume thin specimens are required - how do you get the specimens thin? How thin? How do you handle thin ice?

Etc. etc.
