Here\'s some stuff I\'ve found fun and/or useful with my 1,000mm, 800mm, and 600mm (equiv) lenses:
Newer APS-C or µ4/3 sensor camera. (If 250mm on my µ4/3 is what a fullframmer sees through a 500mm lens that\'s just not long enough for me. And 800mm lenses cost the mega-bucks.)
Equatorial Tracking Mount. $1,100 (MSRP) but you can sometimes find them used on line for around $250 or $300. They\'re good for hundreds of thousands of hours if cared for and used properly so no need to worry about used ones I think.
A modified ski-pole basket so I can use the loaded monopod in the sand, wetland marshes, or snow.
