Thank you.

Hello,
Can you please confirm what is the timestamp when recording airmass in FITS headers?
I assume it is the beginning of the exposure?

Fabio,
Thank you.

Dunnmunro,
Thanks for replying.
As I said I use the GAIA Catalogue.
I am not into guessing.

Patrick.

Fabio, Thank you for your rapid and fulsome response - very clear now. If one does a GOTO using Jnow coordinates it makes sense to me to plate solve to Jnow coordinates during the Centre process. In fact after a GOTO using Jnow coordinates, if Jnow is not selected at the Centre page a warning is giv...

Thank you Fabio.

Hello,
Did this option make it into SP2 and if so how is it selected?

Hello, If I am correct, when saving Plate solve parameters the Region size(RA and DEC) values and the Reference stars value are not saved. So, having plate solved and saved the parameters, I later do a Telescope control GOTO. I insert J2000 RA and DEC values, tick the Jnow box and press Goto. I then...

Fabio,
Thank you.
I shall respond in more detail and with images.

Patrick.

I am a dill!
Thank you

Hello,
With my AA8 Upgrade I downloaded the optional GAIA catalogue but do not have a UCACx (or any other) catalogue.
Should a UCAC have been included (I may have deleted it !!) or has it been replaced by the GAIA?
Am I able to obtain the UCACx catalogue?

Patrick.

Hello,
1) I am familiar with the Bahtinov technique but am looking for descriptions of how to integrate this into Astroart processing?

2)Also looking for descriptions of how to integrate focusing on a spectral line into Astroart processing - especially finding the width of a line?

Patrick.
