Hi folks,

Has anyone used a CS lens with a guide camera instead of a cheshire eyepeice when collimating their Newtonian?

I'm assuming this actually works, and would provide a centered view down the focuser tube. Trying to determine which lens would be best to use with an ASI290MM mini.

Thanks in advance,

Nikko

Is in german langauge, but perhaps can subtitles help.

Hallo Haakon,

Yes! That's exactly what I was imagining. The click-lock adapter for centering is a great idea, too. Thanks for sharing!

Vielen dank,
