Thanks

Hi Fabio, Re Mira - its rapidly dimming and was not really visible naked eye but that was largely due to a bright Moon. When I had Mira centred on the camera it was not all that easy to shut the exposure down enough to prevent Mira saturating and at the same time see the other fainter stars that wer...

Hi Fabio, I have now managed to get things sort of working when using UCAC4. However, even UCAC4 does not have stars close to objects like Messiers. Therefore, even when using the UCAC4 Star Atlas I still could not get a result for the M27.fit example file. However, when I loaded M65.fit it worked v...

Thanks Fabio, I have now installed the GSC catalogue and I have managed to follow along with the Tutorial #3.9 and got both the Astrometry and Photometry working for M57. However when I load in M27.fit and reposition the Star Atlas on M27 I cannot see any obvious correlation between the stars. So th...

OK, so I got my AA7 as an upgrade to AA5 as a download.

There does not appear to be any Star Catalogues included with my download.

So where do I find the GSC to use with Astrometry and Photometry?
