Not as scary as you may believe. I think you will get a deep sense of satisfaction when all is done and your DSLR gets focus.
Read the article by Alchemy in the article section first and apply the measuring up procedure to see how much needs to cut off.
Good Luck and be strong especially when wielding the angle grinder.

my home handyman skills are definitely lacking so would probably cut along the tube and not across it.

you should see my attemptes at mortise & tennen joints!
what a dilemma- galaxies or widefield...
