Hi, I am hoping this is a basic question.

This is the first time using PHD2 and was looking at making a dark frame library.

The guide camera i am using is a ASI290mm mini and it is connected to an Orion 60mm guide scope.

What should i be setting the minimum and maximum exposures at?

The manual just gives some generic numbers of 1.5s for minimum and 5s for maximum with about 5 exposures.

Can anyone please advise me on what some good numbers for minimum and maximum would be for this setup please?

Any advice would be greatly appreciated.

Thanks.

I go from 0.5 seconds to 5 seconds and leave it at 5 exposures.  I pretty much always guide with between 1 and 3 second expsoures, but I just go for a little wider range in case I might use them for some reason.  The whole process doesn't take long so why not.

Thanks for the replies.

Very much appreciated.

I figured it would be a simple answer regardless.

Thanks again.
