Bahtinov grabber settings

[Bubbles82]

Need a little help with the telescope settings for this software .

Scope is ed80 with skywatcher reducer/ flattener.

Camera atik314l+

My question is do I need to account for the reducer in the focal length settings? If so I assume I just times 600 by .8 to get the focal length

So far I have entered

0.080 for the diameter

6.45 for the pixels size

Is this right or have I got this wrong thanks in advance

Yes, I think you need to account for the focal reducer, so a 0.8x reducer would give you a 0.48m focal length.

The Skywatcher reducer is 0.85x though, isn't it?  That would give you 0.51m
