Have a look at Bintel’s astronomy calculator or better still give them a call. According to their astronomy tool this camera/telescope combination produces significant oversampling at f10 which only gets worse with Barlow’s.

Now I must say I am not an imager but have been looking at various camera/telescope combinations should I ever want to try some imaging.

See https://www.bintel.com.au/tools/astr...v=322b26af01d5

If I change the focal length to say 540mm, f5.4 then this camera is a good choice.

Note instead of picking the telescope and camera from the list just enter the parameters manually. You can get the camera pixel size and number of pixels from their web site offering the cameras. This is because not all the cameras and telescopes are listed in the drop down.

I’m not really sure how much of an issue oversampling is especially significant oversampling. Imagers can perhaps answer that one.
