BRESSER MikrOkular Full HD eyepiece camera

[Z3JohnLB]

I have a GSO 8" dobsonian and using the Bresser camera for solar system imaging. I intend to use my x2.25 barlow as well. Just wondering if there is a limit on how much magnification you can get with a camera, and how would I know if I have reached that. I know that with eye pieces it is 400 with this telescope.

Thanks,

John

Ignore terms like "magnification" when referring to imaging, it is impossible to compare visual magnification and imaging limiting resolutions. Take a look at this  astronomy.tools FOV calculator. Select your camera and telescope from the drop down lists, or input the specifications manually, and check the results. For solar system imaging you should aim for 2 or 3 pixels per arc second of resolution (Dawes limit of the telescope) to optimise the camera/telescope combination.

Not sure what this means

[Cornelius Varley]

The Dawes Limit (resolving power) of the telescope is 0.58 arc/secs. The resolution of the telescope/camera combination is 0.23"x0.23" arc/sec per pixel. This falls between 2 and 3 pixels per arc/sec of resolution (0.58 / 0.23 = 2.522). This gives a good imaging resolution for solar system imaging.

Thank you for your help, I shall persevere!
