There is pretty good image sharpness all across the frame.
Theres some
The only issue I can really see is being an F8 lens. so full 30 second exposures at a high enough iso are needed to get any kind of stuff visible.
Is there any tips I could get for maximizing the use of it? I have a canon 500D camera to use with the lens.
Compared to my 55-250 IS II lens the image quality is almost just about the same.
its Way extremely better than my F5.1 70mm refractor telescope so much sharper all across the image frame.
Even sharper than my F4 100mm reflector telescope
Am I limited to just planets and some stars? or is there any deep space object targets that could work?
heres a test image at F8 with a low iso
