My idea to use this lens on the Star Adventurer mount, how will it look? Here it's mounted together with camera and balance weight.

Compare to my EQ6 mount and peripherals this is a dream of lightweight. But I must have a heftier tripod to it with a 3/8" bolt.

At last I maybe can do astrophotography at dark places, and also bring this equipment with me on vacation. I have to modify the setup a bit to get rid of the balance weight, have to center the camera over the RA axis. The future looks great!

Later test will show if I can polar align at the precision I need to get it track good enough. But I have also read about others who use 300mm lenses in success.
