Lens for a project


Im gonna try out this project, Telescope , as I know nothing about optic or lens function maybe someone could just let me know if I should go for a Tele-Auto 6.3/400 mm or a Sigma 70-300 mm F4-5,6 DL Macro Super.

I asked the creator but as time runs out for me I hope this gives a faster response =)
