Andy,

That  is what I am trying to do.

I have uploaded the error message for people to look at.

This afternoon I am MaximDL training.

Thanks Tony for the housekeeping tips.

I have just bias_dark_flat field corrected my spectrum of p cyg but it won’t open in BASS the following error comes up.

Anybody know how to fix this ?

Regards,

Jack

Andy,

My understanding of calibration is a neon lamp as I own a Lhires III.

Do you mean John is rewriting BASS calibration to include bias-dark-flat field corrections ?

By calibration frames do you mean bias-dark-flat frames ?

The ccd temp was set to -5 c as told by an experienced amateur consequently all spectra taken so far are at that temperature.

Regards,

Jack

David,

Yes.

Thank you for your explanation.

I now understand that it is visible to others but not to me !

Regards,

Jack

[Mr Jack Martin]

Thank you all for your replies.

The Atik 460 is cooled to -5 c is that OK ?

I will read through the BASS project user guide to see if I can create a master dark frame.

I assume the same procedure applies to flats and that I need to take a set say 10 after each observing run. ?

My Lhires II has a built in flat lamp.

Andy,

Thank you for you step by step reply.

This information does not appear to be available from Celestron when looking at the C14 specs or anywhere else.
