Re: what is the magnification of a telescope without any eyepiece

Thank you very much for helping me understand

I see I should be applying the barlow strength to the focal length of the telescope to get the new fl

2000mm * 2x barlow lens = 4000mm fl

Then if I had a 20mm eyepiece, the magnification = 4000 / 20mm, for example.

I have been googling myself regarding finding out magnification without eyepiece but for camera, and I can see now that this is dependant on the camera, and that I need to do some research on how arcsec / pixel related to magnification. So that's fine.

Thanks!
