You have a reasonable amount of data but you'd probably get better results with longer subs, maybe 15 or 20 mins. The KAF-8300 has fairly high read noise and that will be significant on short subs with low signal. Did you see Ray/Shiraz's post on a simple method for determining sub length? It's worth trying: http://www.iceinspace.com.au/forum/s...d.php?t=117010

Wrt processing tricks, are you carefully tweaking the rejection algorithm and parameters to maximise SNR? That's the first basic step to getting the best out of your data.

Cheers,
Rick.
Thanks Rick, i'll check over that thread

For less noise, 12 off 20min subs would probably do better.
Thanks Fred, i'll do a repo on this one and see if I can remove the cast

Thanks Geoff
